koi pond filter understanding koi pond filter system

koi pond filter

koi pond filter is very important because without a filter is like living in a room full of shit

So this article will discuss the best practices in building a koi pond filter systems or a DIY koi pond filter

koi pond filter necessary if you want your koi to reach their full potential. You are probably thinking, “Wait a minute! I’m not sure I want to the amount of breeding that would require me to have to worry about all of this!”

Whether you just plan to sell off your excess koi in order to help to
offset some of the cost of keeping them, or you have grandiose
plans of developing a new variety of Koi right in your backyard
pond, you DO need to worry about aerating and filtering the water in that pond.

Treat Your Koi as Your Pet

The Koi you will be keeping in that pond should be considered as much of a pet as your dog or cat. As such, your fish deserve the best of care.

That includes water to swim in that has been filtered to remove any
harmful material and the waste products from the fish.

What would happen to your pond and to your koi if you decided to do without filtration?

• Your pond will very quickly turn a sickly shade of green due to algae build up in the water.
• Fish parasites enjoy murky, algae-filled water, as do other
creatures that may well harm your fish.

If just one fish in your pond is infected by a parasite or injured by
another creature in the water, the chances are good that all of your other koi will experience the same fate.

• Standing water that is full of algae and parasites really smells
horrible and looks pretty awful, too.

Do you really think your koi could live in all of that muck? Here is a hint – They cannot breathe or live in water like this.

Choose a Good Filtration System
You will definitely have to plan what kind of filtration you will use in your pond.

Do not try to save money by purchasing the cheaper filtration system.

You may well regret it if something goes wrong with the filter and causes you to lose all of your koi.

Most experts recommend that you choose a filter that is able to handle 33% of the total amount of water in the pond.

As an example, a pond that is capable of holding 3000 gallons of
water needs a filter that can circulate 1000 gallons of water.

If you must dip lower than this percentage in order to get a filter
you can better afford, you should not choose a filter that circulates less than 10% of the total water volume.

Your pond filtration system should consist of two types of filtration. These are –

  • Mechanical filtration
  • Biological filtration

How Filters Work
Mechanical filtration works by trapping debris and fish waste as
they flow through the water with the use of brushes, pads, sand, or small beads.

Biological filtration involves a natural method that changes the fish
waste into amalgams that will not hurt the fish.

All koi have ammonia in the excretions, and a build-up of ammonia can kill any fish.

Bacteria that are present in a biological filter change the ammonia
and nitrates in the pond water to nitrites, which are safe for koi.

Your filtration system will also need a pump. You have two choices of what type of pump to place in your koi pond.

The types of pumps available are –

  • Airlift pump
  • Subersible pump
  • Recirculating pump

The submersible pump is a good choice for a smaller pond. If your
pond will feature a waterfall, a submersible pump can be used to handle the volume of the waterfall alone.

A recirculating pump is usually what is used for good-sized ponds. They are sturdy and efficient, and most will serve you for a long time.

Does a koi pond need a filter?

You can use a koi pond to grow water plants, but more often than
not, a water garden is an inadequate environment raise koi.

So what exactly do you need to have in a good koi pond? Not much, really.

There are five must-haves: bottom drain, surface skimmer, pump, filter, and ultraviolet light.

What is a biological filter for ponds?

Biofilter, a biological pond filter. A biofilter is a biological filter that provides a pond with water that is rich in carbon dioxide.

Carbon dioxide is very important for water plants.

They, in turn, keep pond water clear and clean.

How does a gravity fed pond filter work?

In principle, a gravity fed filter works in the opposite way to a
pump fed filter system, with the pump drawing water way from the
filter either via a suction hose, or been situated in the filter’s final

Because gravity will always keep the water levels equal,
when the pump pulls water from the filter, pond

How does a biofilter work?

Biofiltration is a pollution control technique using a bioreactor

containing living material to capture and biologically degrade pollutants.

Common uses include processing waste water, capturing harmful

chemicals or silt from surface runoff, and microbiotic oxidation of contaminants in air.

How long does a biofilter take to work?

When a new pond is built it will typically take 4 to 6 weeks before the biofilter is working effectively.

Therefore during this period introduce new fish slowly.

How do I make my pond water clear naturally?

  1. Maintain a healthy fish population.
  2. Don’t over-feed your fish.
  3. Create a proper balance of plants.
  4. Choose the right size pump for your pond.
  5. Clean debris from pond before it has a chance to decay.
  6. Choose proper filtration for your pond.

What is the function of mechanical filtration?

The principle behind mechanical filtration is simple. The idea is to physically remove particles, and waste matter from the aquarium water.

Many times a fine medium such as cotton, dacron, and other
synthetic materials are used to trap detritus, dead plant matter, and other debris.

Do nitrifying bacteria need light?

Nitrifying bacteria do not form spores. They have a complex cytomembrane (cell wall) that surrounded by a slime matrix.

All species have limited tolerance ranges and are individually

sensitive to water temperature, pH, dissolved oxygen levels, salt,
micronutrients, light, and inhibitory chemicals.

indian almond leaf locally known here in my place as  “Talisay leaf” is commonly used as betta fish breeding stimulant by local betta fish breeders but the breeders here did not really know what are the reason and properties that the indian almond leaf has that can stimulate the betta fish to breed.


They used it also to treat sick betta fish and groom betta fish coloration but not knowing the background of the indian almond leaf ingredients that has the antifungal or antibacterial properties.


Let’s dive into what are the benefits of Indian almond leaf that can give your betta fish

  1. can stimulate the betta fish to breed because of its tannin. The Indian almond leaf tannin can change the water chemistry of your breeding tank turning it similar to the betta fish natural habitat in the wild and for this reason, the betta fish will be triggered to breed.
  2.  can be used as betta fish conditioner for battle preparation and helps cure the wound after battle
  3. can be used as water conditioner for newly bought betta fish this will help the newly betta fish adjust faster to its new home.
  4. can also be used as betta fry food when added to the betta fry tanks since it can introduce an infusoria culter 
  5. also can be used as a color enhancer to betta fish

indian almond leaf extract for betta fish

If you’re an Betta fish keeper, you are a fan of using  Indian almond leaves (also known as Catappa leaves). for your Betta

These leaves of the Terminalia catappa tree are especially popular in the betta and shrimp hobby as a natural medicine and water conditioner.

It can be used as a combat fungus and bacterial problems like finrot, and prevent stress by mimicking the natural habitat.

But how, when and why should you use them?

What are Indian almond leaves?

As mentioned before, Indian almond leaves are the leaves of the Terminalia catappa tree, which grows in large parts of Asia.

The leaves are usually harvested by simply picking them off the ground. After drying them, they are ready for use in the aquarium.

You can import Indian almond leaves directly, but nowadays they are also available in some pet-/aquarium stores and online!

What do Indian almond leaves do?

When placed in an aquarium, Indian almond leaves slowly start to decompose.

While this happens they turn the water a yellow or brown color by releasing tannins.

These tannins lower the pH and are said to have antifungal and antibacterial properties, which comes in very handy when you have a fish suffering from finrot or when you’re raising vulnerable fry.

The dark color of the water is considered unsightly by some aquarists, but it actually mimics the natural habitat of many fish species! This definitely makes it something to consider embracing.

Based on my personal experience  I will testify that adding Indian Almond leaves in your betta tank will make your betta fish healthier and spawn faster.

Evenly newly bought betta fish when you add Indian Almond leaves to its tank it can recover immediately from transportation stress and even shown spawning behavior immediately by building bubble nest immediately.

I personally testify it.

If I missed something about talisay leaf other uses please feel free to leave it in the comment section below or to my youtube video your comment and suggestion is highly appreciated.

What are Indian almond leaves used for?

Indian Almond Leaves are commonly used for conditioning and care of Bettas. …

Simply adding Indian Almond Leaves to your aquarium will release compounds from the leaves which alter the chemistry of the water,

making the aquarium more similar to the habitat from which the fish hails.

What is the common name of Terminalia Catappa?

Terminalia catappa is a large tropical tree in the leadwood tree family, Combretaceae, that grows mainly in the tropical regions of Asia, Africa, and Australia.

It is known by the English common names country-almond, Indian-almond, Malabar-almond, sea-almond, tropical-almond and false kamani.

indian almond leaves this is a good article from indianalmondleaves.com

Using Indian almond leaves in aquariums
Indian almond leaves (IAL) have traditionally been used by Betta (Siamese Fighting Fish) breeders in South East Asia to mimic the natural Betta habitat.

They are believed to aid the fish in a number of ways, such as helping fighting fish heal after a battle and inducing spawning in breeding tanks.


Unfortunately, the affect of Indian almond leaves on aquarium fish has not been scientifically studied yet so it is difficult to separate the truth from the myth.

I can only speak from personal experience and my own good track record using Indian almond leaves, and base my conclusions on reports gathered from other fish keepers.


Why do aquarists use Indian almond leaves?
The poor man’s water conditioner
Indian almond leaves are often described as ”the poor man’s water conditioner” due to their capacity of altering the water chemistry in an aquarium.

In the wild, fish evolve to fit into their particular habitat and having to live in another type of environment in captivity is often difficult for them.

Even if your fish manages to survive in less than ideal conditions, there is a great difference between thriving and merely staying alive.

If your fish hails from a habitat where leaves and other plant debris regularly falls into the water and decompose, your fish will be used to that kind of environment and trying to mimic it in the aquariums is strongly recommended.

Leaves that fall into the water release a myriad of different compounds, from trace minerals to dyes, and animals living in the water adapt to having all these different compounds readily available.

When we place fish in our “clean” and rather unnatural aquariums, we in avertedly deprive them of access to a long row of different compounds present in their native habitat.

If your fish hails from the type of environment described above, Indian almond leaves are one way of making life in captivity a little more natural for your pet.

Just like driftwood and peat, Indian almond leaves release ample amounts of tannins into the water. The tannins affect the pH-value (how much will depend on the buffer capacity of your water) and you will also see how the water turns dark – just like a blackwater river.

Needless to say, water rich in tannins is appreciated by fish species that hail from such environments in the wild. So called blackwater habitats are formed when rivers flow slowly through heavily forested areas where falling leaves and other plant debris end up decomposing in the water.

You can find more detailed information about the chemistry of Indian almond leaves in on the Indian almond leaves chemistry page. That page also includes a section on blackwater habitats.

N.B! Using almond leaves will give the water in your aquarium a yellow to reddish tea-coloured shade. Exactly how dark the water gets depends on the concentration of tannins in the water.

Some aquarists dislike this tint which they find unsightly, but try to keep in mind that for fish hailing from blackwater habitats this dark water is actually the normal state of things and the crispy “clean” 100% transparent water without any hint of colour favoured by many aquarists is quite unnatural for them.

Is it true that Indian almond leaves prevent and cure diseases in aquariums?
Indian almond leaves are rich in compounds produces by the tree to protect itself against bacteria, fungi and similar organisms.

Because of this, it has been speculated that adding Indian almond leaves to an aquarium will decrease the risk of disease in the tank or even help fish. As far as I know, no one has yet carried out any scientific study to verify this claim.

Compounds found in Indian almond leaves have however been researched for their potential health benefits for the human body.

Quercetin, a type of flavonoid found in Indian almond leaves, is for instance considered anti-inflammatory and has antioxidant properties1 , while several other flavonoids present in these leaves – such as kaempferol – decrease the risk of developing certain types of cancer.[2 ][3 ]

Fish kept in an environment that mimic its natural habitat tend to grow stronger and heartier, i.e. more apt at fending off malicious microorganisms.

As an aquarists, it is therefore difficult to determine if Indian almond leaves actually cures and prevent disease by killing of bacteria and fungi, or if it is simply a question of the leaves boosting the fish’s own immune system by providing it with an ideal water quality when it comes to pH-value, tannins, etc.

Natural hiding spots and infusoria supply
Using Indian almond leaves is not just about chemistry. You may think leaf litter looks ugly, but for a long row of fishes it feels just like home. Leaves and leaf litter makes the environment more natural.

Bottom dwelling fish love to hide among sunken leaves, while surface and mid-water dwellers like the sense of security offered by floating leaves.

Indian almond leaves are also nice for fish and invertebrates to nibble on between meals, and the leaves serve as home and food for infusoria.

Can Indian almond leaves be used to change the sex ratio of Betta fish?
A lot of rumors circulate about South-East Asian Betta breeders using Indian almond leaves to increase the male-to-female ratio in the batches. Personally, I’ve noticed no difference in sex ratio when using Indian almond leaves.

When do aquarists use Indian almond leaves?

Indian Almonf leaf
What fish will like Indian almond leaves and what won’t?
Indian almond leaves are ideal for fish that hails from environments where the water is rich in leaf debris. A few examples of such fishes are bettas and other gouramis, blackwater tetras, discus, rasboras and many dwarf cichlids. You need to research your particular species to see if it hails from this type of water.

Indian almond leaves are not recommended for fish that like hard and alkaline water, such as African cichlids from the Great Rift Valley lakes.

Examples of situations when Indian almond leaves are commonly used
Some aquarists use Indian leaves all the time, while others use them only for special purposes, i.e. when the feel that their fish needs some extra pampering. It is especially common to use IAL…

  • When setting up a new aquarium
  • When a new fish is introduced to an aquarium
  • To induce breeding, especially in Bettas
  • When setting up and maintaining a fry aquarium
  • When a fish is sick, especially if the sickness affects the skin
    In the plastic transport bag when a fish is moved to a new home
  • When keeping delicate fish species that are considered difficult to keep and breed in captivity
    If you use Indian almond leaves all the time, remember that you may have to “wean” your fish off them if you plan on selling your fish to an aquarist that won’t use Indian almond leaves. A fish that has been raised among Indian almond leaves or spent a long time in an IAL-tank may not handle a rapid move to a different environment well.

How do aquarists use Indian almond leaves?

Keep your Indian almond leaves in a dry place at room temperature until you wish to use them. Dry leaves can be stored for at least 6 months in a suitable environment (preferably a container that is airtight, watertight and prevents light from entering).
If the tree may have been sprayed with pesticides or grows in a big city with lots of pollution, rinse the Indian almond leaves well in tap water before placing it in your tank.
Do not use Indian almond leaves that are mouldy.
Remove active carbon, purigen and similar from the aquarium before adding your Indian almond leaves.
If you’re in a hurry, you can cut the leaves into smaller pieces since this will make them leach their content into the water more rapidly.
Dosages below are based on 15-25 cm (6-10 in) leaves. If your leaf is smaller or bigger, you need to adjust the figures accordingly.

Using 2 leaves per 50 L (13 us gallons) of water is a good rule of thumb, but be prepared to adjust the dosage to suit your particular fish. Some Betta keepers routinely use up to 2 leaves per 15 L (4 us gallons) of water in their everyday tanks.
Betta breeders normally use 1 leaf per 20 L (5 us gallons) of water in breeding tanks.
In fry rearing tanks, use 1 leaf per 40 L (10 us gallons) of water.
For how long?

Unless you anchor the leaves using a rock or similar, they will normally float for 2-3 days before sinking. Sinking is natural and it doesn’t mean that your have to change the leaves.

The leaves will normally disintegrate after a month or two, depending on how actively your fish tries to destroy them.

Aquarists that dislike the sight of torn leaves normally replace the leaves every 2-3 week, but this is purely for aesthetical reasons.

There is usually no need to change the leaves more often than every second month.
Indian almond leaves in fry tanks

In a fry tank, Indian almond leaves are beneficial in several different ways. In addition to all the positive effects described above, the leaves serve as home and food for infusoria; minute aquatic creatures like ciliates, euglenoids, and protozoa.

Due to its size and nutritional content, infusoria is an excellent food source for newly hatched fry from a long row of species.

In addition to this, many species of fry are naturally inclined to hide among leaves and leaf litter and will feel safer and less stressed in a fry tank that isn’t completely barren.

Indian almond leaf for hospital tank
Instead of routinely adding Indian almond leaves to the aquarium, some aquarists prefer to set up a separate IAL-tank and let their fish spend some time in it when the fish seem to be a bit under the weather, e.g. due to skin abrasions.

This is not a quick fix – you should be prepared to let your fish stay in the hospital tank for at least 2-3 weeks. (Having a separate hospital tank will also prevent spreading of infectious disease and keep other more healthy fish in the main aquarium from taking advantage of a weakened tank mate.)

As always, the hospital tank must naturally be very similar to the ordinary aquarium when it comes to temperature etc, otherwise your will shock your fish.

Traditional conditioning for Siamese Fighting fish
According to professional breeders of Siamese Fighting fish in South East Asia, Indian almond leaves will harden and coat the skin of the fish, thus making it more apt for fighting.

The idea is that Siamese fighers living without Indian almond leaves have softer skin and scales that aren’t smooth and slippery enough to handle being bitten by other fighters.

The fish is therefore conditioned using Indian almond leaves for at least seven days prior to a fight. A clay pot is filled with clean, aged water, the leaves are added, and the fish will live in the pot and be fed live food once a day.

The pot is placed in a dark and quite place to help the fish prepare.
After a fight, a similar treatment is given to help the fish recover from its injuries.

Frequently Asked Questions
Is it true that Indian almond leaves remove heavy metals from the aquarium?
I come across this claim now and then, but I have seen no explanation for exactly how it would work or any scientific studies regarding IAL and heavy metals.

Bogwood is commonly used among aquarists to reduce the toxicity of metals; perhaps decaying leaf matter works in a similar way.

When organic matter (i.e. not just Indian almond leaves) are turned into humus by bacteria and fungi, toxic substances such as heavy metals can be chelated, i.e. bound to the complex organic molecules of humus.

This can prevent the metals from entering the wider ecosystem, but will not remove them. For us aquarists, it means that the heavy metals will still be present in our tanks – only bonded to humus.

I have never used copper based medication in an aquarium together with Indian almond leaves so I can’t tell if the leaves decrease the effectiveness of the medicine or not.

Can I use Indian almond leaves in my planted tank?
Yes, Indian almond leaves can safely be used in planted aquariums. Of course, plants that like alkaline waters won’t appreciate the drop in pH-value, but why would you keep such plants with acidic loving fish in the first place?

Can I combine Indian almond leaves with activated carbon or purigen?
Activated carbon, purigen and similar will decrease the effect of Indian almond leaves and should therefore be removed from the aquarium prior to IAL use.

Is there any way of getting rid of the colour?
If you for some reason wish to get the tannins out of the water, you can use activated carbon or simply do a lot of water changes. Just remember that the positive properties of the Indian almond leaf will vanish as well.
Alternatives to using whole leaves

Indian almond leaves in a tea bag
If you hate the look of Indian almond leaves in your aquarium, there are vendors that sell IAL tea bags to soak in the water. Of course, using teabags will not give your fish any leaf litter to hide among or nibble on.

Making your own Indian almond leaf concentrate
Another alternative for those who dislike having leaves in the tank is to boil the leaves and make a concentrated Indian almond tea to pour directly into the aquarium water. Simply place the leaves in a pot filled with water and bring to a boil. Boil until the water darkens. The tea can be stored in an airtight bottle in the fridge.
Recipe for a 375 L or 100 us gallon aquarium:
15 to 20 leaves (15-25 cm / 6-10 in)
10 L or 2.5 us gallons of water
N.B! The tea must naturally have roughly the same temperature as the aquarium water when you add it, i.e. not to warm or too cold.

What do Almond leaves do for bettas?

The tannins released by the leaves help create water conditions that are similar to those in the natural habitat of the fish, which means ideal breeding conditions.

If you’re trying to get your bettas or Crystal Red shrimp to breed, adding a few Indian almond leaves to the breeding tank can speed up the process!

What do Indian almond leaves do?

Is Talisay fruit edible?

The seed within the fruit is edible when fully ripe, tasting almost like almond. As the tree gets older, its crown becomes more flattened to form a spreading, vase shape.

simple guide to aquarium filtration

To have poison free aquarium water, filtration process is a
very important to aquarist.

Since most aquarists are aware of the fact that their aquarium water
accumulates harmful substances, which poison their fishes.

To prevent this from happening there is need for filtration here’s the simple guide to aquarium filtration thus, for our purpose I would define filtration as the removal of unwanted substances from water.

To have poison free aquarium water, the filtration process is a
very important to aquarist.

Since most aquarists are aware of the fact that their aquarium water
accumulates harmful substances, which poison their fishes.

To prevent this from happening there is need for filtration
thus, for our purpose I would define filtration as the removal
of unwanted substances from water.

Most aquarist uses three types: Biological, mechanical, and
chemical amongst which the biological is the most important.

Biological filtration is also referred to as undergravel filtration,
because the major equipment used (a flat plate of perforated
plastic) is placed under the gravel bed hence it is invisible.

Unless you are properly equipped, you can’t see the process
happening and cannot measure its effect.

Yet this process is the major difference between success and failure,
and the aquarist who does not take the time to understand it
workings is doomed to watch an endless procession of dying fishes
passing through his tank.

Biological filtration is solely the work of bacteria attached to the
surfaces of the gravel, the grave and the under grave filter together
constitute the filter bed.

Bacteria normally reach the filter bed through the food you give the fishes.

The waste product of the fishes, the air, and even through your hands as you works in the tank.

As the water ages, their numbers increase until the gravel is loaded with millions of them.

It is only then that the aquarium can function very well, because
the wastes of the fishes and unwanted substances mainly ammonia
are immediately broken down by those bacteria into harmless
substances while at the same time the filtration action drags organic
matter downwards into the spaces between the gravel’s where the
roots of plants can then extract essential growth substances hence
the undergravel filter promotes healthy plants growth.

Mechanical filtration is the physical removal of debris, waste
products, uneaten food, dead fish or plants.

They use a filter medium such as foam, filter wool or sand/gravel
to trap particles which are removed by later cleaning of the medium.

Chemical filtration changes the composition of some substances in the aquarium.

Ammonia absorbers, such as Ammogon tm help prevent problems
when water aging is done chemically (treatment with chloramines releases free ammonia).

Other “chemical” filtration includes ion exchangers which reduce either carbonate or sulphur hardness.

simple guide to aquarium filtration An effective aquarium filtration system not only removes waste products from the water by physical or chemical means, but also mirrors the process of biological filtration—the nitrogen
cycle—that occurs in the wild. Filtration goes hand in hand
with aeration, in which water is circulated so that it can absorb
oxygen from the air and lose unwanted carbon dioxide.

In the confines of an aquarium, thewaste produced by the fish can
quicklybuild up to harmful levels without aneffective filtration system.

Filtration involves passing the water in the aquarium through one
or several filtration media, which purify the water by biological,
chemical, or mechanical means (see box, below).

There are two basic methods of driving water through the media:
using an electric pump, or using an airlift system, in which air
bubbled into the tank through an airstone draws water up an airlift tube.


  • Add zeolite sachets to remove ammonia from the water, and a
    starter seed culture of bacteria for the biological filter.
  • Be careful not to overfeed the fish and burden the filter with decomposing food.
  • Test the water quality regularly to check the filter’s efficiency;
    frequent partial water changes will ease the pressure on the filtration system.

simple guide to aquarium filtration

simple guide to aquarium filtration filtration methods

The most common type of system for freshwater aquariums—
the undergravel filter—is a simple airlift system.

A perforated corrugated or ridged plate is placed on the base of the
tank, and then covered by a substrate of gravel.

The plate allows water to flow under the gravel, while the gravel
particles— which should be at least 1⁄8 in (3 mm) in diameter to
ensure good water movement—form the biological filter medium.

Power filters use an electric pump to drive water through the filtration media.

There are two basic types: internal power filters, which sit inside
the tank, and external filters, which are housed outside the
aquarium and are generally used for larger aquariums.

A range of different media are available for power filters: biological
media, such as foam sponge and ceramic granules; mechanical
media, such as filter wool; and chemical filtration media, such as carbon.

The most efficient filters use layers of different media in combination. It is often

possible to add extra materials—for example, peat or
coral sand—to this type of filter to alter the water chemistry.

Efficient aeration is vital for the maintenance of a healthy
tank, providing a source of oxygen not only for the fish, but
also for the beneficial bacteria within the biological filter.

Using an air pump to pump air through an airstone can help to
aerate the tank: the bubbles produced cause surface ripples that
increase the area exposed to the air where oxygen exchange can take place.

But, if there is enough surface movement generated by the
outflow of the filtration system, an extra air pump may not be needed.

external filter system


External power filters work on the same principle as other systems:
water is pumped out of the aquarium and passes through the filter
unit, which contains one or several types of media, before being returned to the tank.

how to acclimate fish

The availability of pond fish is seasonal, with the largest selection
offered for sale during the spring and early summer months.

varieties that overwinter in the pond the opportunity to become
well established before the onset of colder weather.

Always obtain pond fish from a reputable supplier who allows you
to inspect the fish before purchase.

Most aquarium stores offer a range of coldwater fish, but if you
want exhibition-standard koi you should seek out a specialist dealer.

Pond fish are usually priced by size, with the largest individuals
commanding the highest prices.

House newly acquired fish in an indoor aquarium or a small
outdoor pond for a week or so before transferring them into
the main pond, to be sure they are healthy.

If you have only recently filled the pond, treat the water with the
appropriate amount of dechlorinator before introducing the fish.

Stocking levels in a pond without filtration should not exceed 2 in (5 cm) of fish for every 1 ft2 (0.09 m2) of pond surface area.


  • Make sure your chosen fish is swimming without difficulty through
    the water before asking for it to be caught.
  • View the fish from both sides, because a problem may be evident on one side only.
  • Inspect the fish closely for signs of skin damage, including missing
    scales or reddened areas on the body.
  • Look carefully for any signs of external parasites, which are hard to cut from a pond.


Most fish can be transported from the supplier to your pond in
large plastic bags, but very large koi may have to be moved in vats.

Care must be taken when transporting fish, to avoid subjecting
them to unnecessary stress.

If possible, use a local supplier to minimize the traveling time.

Adding oxygen to the traveling bag lengthens the time that the fish
can be kept in it, but never keep them confined for longer than necessary.

aquarium aeration essential factor to aquarium fish

aquarium aeration

Properly aerating your aquarium allows your fish to breathe
properly, which is essential for good health.

The devices most commonly used to increase aeration in fish tanks
are filters, power heads, air stones, and aerating decorations.

Use whatever combination you like to provide your fish with the oxygen they require.

As we all know rivers and lakes are the natural habits for fish and other marines.

Rivers and lakes have large surface area which makes maximum
provision of oxygen for fish survival possible.

On the other hand aquarium is not like river or lake, it has a smaller
surface area and there is limited movement of habitats.

As we all know rivers and lakes are the natural habits for fish and other marines.

Rivers and lakes have large surface area which makes maximum
provision of oxygen for fish survival possible.

On the other hand aquarium is not like river or lake, it has a smaller
surface area and there is limited movement of habitats.

This makes provision of alternative means of oxygen for fish to breathe important.

This artificial process of providing oxygen is called aeration. It’s a simple process of re-oxygenating the water in aquarium tank.

The Aerating System:

This is the series of material that increases the supply of air
(thereby increasing oxygen concentration) they are:
the air pump
rubber tubing
clamp or regulator
diffusers or airstone

Air pumps come in different shapes and sizes but the most popular
ones are tecax air pump from Taiwan together with ‘dyna free, and
the dragon’ another popular one is super 555 from India though cheaper, but not as rugged.

Occasionally available are the more expensive whisper and rens air
pumps from Uk and rance respectively.

Always place air pumps above the water level hooked to a non-vibrating material.

You can accomplish aeration in your aquarium tank by using the
above listed aeration materials.

This materials form aquarium aeration system. For small tanks all you need is to attach simple aquarium air pump to airstone by means of rubber air tube.

The system will be blowing air into the water which cause motion
in aquarium tank and thus provide necessary oxygen your fish
needs to breathe in aquarium.

Are bubbles necessary in an aquarium?

Dissolved oxygen is very, very important to fish, to bacteria, and even to plants at night.

Plants and algae need oxygen at night. So air pumps are relatively inexpensive.

Depending on the needs of the aquarium fine bubbles will give you
a little bit more surface area, and that’s going to give you more oxygen.

Can you aerate an aquarium too much?

And in aquariums, certain types of filters help aerate the water as well.

These include hang-on-back filters and trickle filters. … Too much
oxygen in water can lead to the potentially lethal gas bubble
disease, in which gas comes out of solution inside the fish, creating bubbles in its skin and around its eyes.

How do aquarium air stones work?

The air stone will increase the water circulation more than an
undiffused air feed into the tank from an air pump, and the
bubbles themselves will also increase the surface area of the water
more, but the real benefit from an air stone as far as oxygenation goes is just the increase in circulation.

Do aquarium filters aerate water?

The surface tension of the water must be broken for sufficient gas exchange.

Fortunately, creating surface agitation is easily done with aeration,
or pumping air into the water so that it forms bubbles.

These air-lift filters use this technique to pull water through their
filter media and thus clean the entire tank.

Do fishes need oxygen?

Fish need oxygen too, but since they don t have lungs, they take oxygen from the water in which they live.

The oxygen in the water available to fish is called dissolved oxygen
(oxygen that is dissolved in the water).

Fish use gills to take oxygen from water just as we use our lungs to take oxygen from the air.

Does goldfish need air pump?

Do goldfish need an air pump? New goldfish keepers often see air
pumps in goldfish tanks and assume that they are strictly required
and that the fish will suffocate without one.

You may be surprised to hear that all of those bubbles from the air
pump don’t actually add much oxygen to the water at all.

Are air stones good for aquariums?

Because they use such a high temperature when sintering, these
stones are really durable and dissolve oxygen at a high rate.

Plus, they put out a lot of tiny bubbles instead of a small number of large ones which most fish and plants prefer.

They’re great for fish aquariums as well as hydroponics.

Is an air stone necessary in an aquarium?

One of the most common misconceptions in the aquarium hobby,
possibly second only to “fish will not outgrow their aquarium”, is
that you need an air pump and air stones to provide sufficiently
oxygenation to that tank to keep the fish healthy, and that the air pump provides oxygen to the water.

How do you know if your fish is getting enough oxygen?

That is perfectly normal behavior, and the fish will not remain on
the surface taking breath after breath.

When fish go to the surface of the water for oxygen, they will gasp repeatedly, often with a wide open mouth. If all of the fish are gasping at the top, the problem is critical and swift action should be taken

Why are my fish at the top of the tank gasping for air?

What should I do if my fish are gasping? The water surface contains
the highest levels of dissolved oxygen, so when fish can’t get enough they’ll rise to the top and gasp.

However, the cause of that gasping could be due to several factors. The warmer the water gets, the less oxygen it holds

Do I need an air pump in a planted aquarium?

Do You Need Air Pumps in Planted Aquariums? All that an air
pump does is create a surface current and add oxygen to your
aquarium near the top where the water gets disturbed from the breaking bubbles.

This can also be achieved by using power heads at each end of your aquarium or just on one side.

should be performed on smaller time intervals, perhaps once a week.

When performing maintenance operations to your aquarium, you
should always keep in mind a few things to ensure that things are
going smoothly inside your aquarium.

Check the air pump and see if it is running ok. It is imperative that there is enough oxygen for the fish but also to allow for proper flow of the water.

Another thing that will ensure longer life for your aquarium is
ensuring that the water is changed often.

This way your fish and plants will live longer and your aquarium will definitely look better.

One more thing that you should do to maintain a clean aquarium is
to clean, or at least rinse the gravel that sit on the bottom of your aquarium.

This process entails that you remove all contents of the aquarium including the fish.

Therefore, its viability depends highly on how many as well as what kind of fish you have. Keeping a clean aquarium does not only entail cleaning it every week or two weeks.

You should also consider acquiring a water purifier. There are many kinds of purifiers out there for different types of aquariums as well as sizes.

koi painting koi fish feng shui digital print on canvas can bring luck to your home too.

Koi is the next prized fish in the feng shui world. A decorative variety of carp, koi come in several bright colors such as red, yellow, blue, white and sometimes black.

The typical number for Koi fish in a feng shui aquarium is 9 (8 brightly colored koi and 1 black koi fish).

The black fish is there to neutralize bad luck. You can also find feng shui cures with 2 koi fish, this being a feng shui cure to attract love and fidelity.

There are also paintings with any number of koi fish in a stream, which is used to represent a fresh flow of abundance. Still, best numbers are considered either 9 or multiples of 9.

Koi carps: the feng shui lucky fish
All over the world fish and especially koi carps are regarded as lucky fish that brings prosperity.

Koi carps are also famous for their longevity (one famous scarlet koi, named “Hanako,” was reported to be 225 years).

The fish symbol has long been associated with abundance and wealth in feng shui, thus there are many cures that depict fish for prosperity.

However, there are different types of fish used in feng shui for wealth cures – there is Arowana, Koi fish (carp) and of course, the Goldfish.

There are also specific requirements as to using a feng shui aquarium for wealth and prosperity.

And, what is the difference between various types of fish in terms of feng shui applications?

The symbology of fish, in general, is closely associated with the energy of water.

The mysterious, the unknown, the bringer of life — all these (and more) are associations with the power of the water element.

Feng shui adds the dimension of prosperity and abundance to the meaning of water. However, while widely used in many feng shui cures for wealth, water as a symbol of abundance is not unique to feng shui, but rather common to any culture, especially an agriculture-based society.

So, to put it in very simple terms, water is a life giver, thus a symbol of continuous abundance. The fish would be a giver of sustenance or nourishment, this is why it is associated with health, wealth, and prosperity. The symbol of fish was celebrated as sacred in many cultures and in many stages of human history — from Greek and Roman mythology to the worlds of Celts, Hindu, Buddhism, and Christianity.

In Chinese culture, the symbol of fish is generally attributed two qualities. The first one is the aspect of abundance (because of the above-mentioned qualities, as well as the ability of fish to quickly reproduce in quite big quantities). Then, of course, the Chinese word for fish (yu) is pronounced the same way as abundance.

The other, less-known aspect of Chinese fish symbology, is the fidelity and good companionship association because many fish swim in pairs. So now when you see a Chinese feng shui image with two fishes swimming — which will most probably be Koi fish and definitely not Arowana — you know that you can use this image as a feng shui cure for love and successful marriage (which does include the abundance component, of course!).

In choosing the best feng shui cure for your home, its potency will depend on how well the cure works for your home, as well as how much you actually like the cure. For example, if you love a specific image of fish, and find a place for it in the right feng shui bagua area that really compliments your decor, this will work as an excellent feng shui cure!

On the other hand, if you choose an aquarium because you think it is the best feng shui fish cure, but neither you nor your home actually like it, then its energy will not work as a good feng shui cure for you.

How about the images with many fish, does the number matter? And, as we asked before, which fish is better for attracting wealth and prosperity? Is an image of fish as potent, feng shui-wise, as an aquarium with live fish?

What does Koi Fish feng shui Digital Painting Canvas Painting represent in Fengshui?

Going by the saying, Koi fish are very brave by nature and therefore they represent courage and determination. They fight their way upstream to achieve their target. It is said that this action of the Koi is analogous to human suffering and the toil which human’s see in their lives. These attributes of the Koi fish are seen in many humans who are extremely driven by nature and want to make something of their lives or achieve certain goals.

Another very important thing that Koi fish stand for is status and wealth. In Chinese culture Koi fish represent ‘abundance .Koi fish paintings can attract flow of wealth and luck if placed at appropriate places in the home or business.

Apart from the fact that they beautify the house, a lot of people believe in the Koi’s abilities to ward off bad omen and attract wealth and happiness. The Japanese and the Chinese strongly believe that a Koi fish Painting at home can bring good fortune and good health to the owner.
What kind of Koi Fish Painting is Ideal?

If you wish to have luck and wealth on your side, then a painting of eight red and white Koi Fish is ideal. The number eight stands for prosperity in feng shui practices. Red koi symbolizes true love while white on the other hand is a symbol of progress in career. So, a painting with red and white color koi fish will result in perfect balance and harmony in your family as well as professional life.

Digital painting is an emerging art form in which traditional painting techniques (such as watercolor, oils, impasto, etc.) are applied by means of a computer, a digitizing tablet and stylus, and software. I work with a Wacom tablet, Corel Painter, Adobe Illustrator and Adobe Photoshop.

Digital painting is a type of digital art but it is not computer-generated art, in that it does not involve the computer automatically generating an image from mathematical models created by the artist. In digital painting, the artist uses painting techniques to create the image directly on the computer.

Digital painting is also distinct from digital manipulation of photographs, in that it is an original construction from scratch. While photographic elements may be incorporated into digital paintings, they are not the primary basis or source for them. In some of my images, I use no photographic elements at all.

ranchu goldfish fancy goldfish everything you need to know about

red white ranchu goldfish

black ranchu goldfish

Black Ranchu This the darkest variety. Ranchus are not hardy, and need to over winter in aquariums in temperate areas

Sporting a hood similar to the Lionhead’s, the Ranchu is the
Japanese counterpart of that ancient Chinese breed.

The Ranchu can be differentiated from the Lionhead by its shorter, more steeply
curved body.

As with Lionheads, not all Ranchus display smooth body curvature
from head to tail, and an individual with slight humps along its
back is considered to be seriously flawed.

The double caudal fin may be only partially divided. In Ranchus
of the highest quality, the top edge of the caudal fin should ideally
form an angle of 90 degrees with the caudal peduncle.

Ranchus, which are also known as Buffaloheads, are the most popular Japanese goldfish.

Four principal founding lines are recognized, each of which is
named after its creator.

The dominant variety is the Ishikawa lineage; the others are Sakuri, Uno, and Takahashi.

All these forms display a hood, but some lesscommon varieties lack
this feature.

They include the Osaka Ranchu, named after its city of origin,
which also has a more rounded body.

Another hoodless variety is the Nankin Ranchu, from the
Shimane area of Japan, a silvery-white fish with red
gill covers, lips, and fins.

In addition, there is the rare Nacreous Ranchu, also called the
Edonishiki, in which the hood is poorly developed.

The beautiful Ranchu Goldfish is popular throughout the world. It originated in China and was further developed in Japan in the late 1800s.

With its round, broad body and large bulbous head, it is also known
as the Buffalo-head Goldfish, especially in Asia.

The Ranchu Fancy Goldfish are much prized in Asia, where they
are bred for highly competitive shows.

In Chinese shows, they are judged from the side while in Japanese
shows, they are placed in shallow bowls and judged from the top.

Though they are impressive viewed from either direction, from
above you can see their broad back.

Rather than having the long slender body of the Common Goldfish
or the Shubunkins, the Ranchu Goldfish is one of the more rounded or egg-shaped fancy goldfish.

They closely resemble the Lionhead Goldfish with a compact, broad body and short fins.

Like the Lionhead, the Ranchu lack a dorsal fin and will develop the fleshy ‘raspberry’ head growth.

The Ranchu can be distinguished from the Lionhead by its much
higher, curved contour shape to its back.

Also, its caudal (tail) fin splays out to the sides, often being almost
horizontal, and may have three or four lobes, while the Lionhead’s
caudal fin is quite similar to that of the Fantail Goldfish.

These fish come in a variety of colors but are most commonly bi-
colored, as in the Gold and White Ranchu Goldfish or the Red and White Ranchu Goldfish.

There is a Calico Ranchu Goldfish, which is called Edonishiki in Japan.

They can also be anything from a deep red overall to a reddish
yellow-orange, or they can have red scales edged in white.

In some cases, they can be found completely white or even black.

The Ranchu Goldfish is a rather delicate fish and not recommended for beginners.

Its swimming ability is encumbered by its rounded body and
further diminished by the lack of a stabilizing dorsal fin.

This is a trait that is also seen in the Lionhead, Bubble Eye, and Celestial Eye Goldfish.

Many of the elongated goldfish varieties like the the Common and
Comet Goldfish, or the Shubunkins, are not really good
companions for the Ranchu because they are fast swimmers and
too competitive during feeding time.

Better tankmates would be the other similarly handicapped dorsal-
less goldfish, or the less hardy Telescope and Celestial Goldfish.

The Ranchu won’t win any races, but if kept with other slow-moving varieties, it should get plenty to eat and do well.

Habitat: Distribution / Background

The goldfish of today are descendants of a species of wild carp
known as the Prussian Carp, Silver Prussian carp, or Gibel Carp
Carassius gibelio (syn: Carassius auratus gibelio), which was described by Bloch in 1782.

These wild carp originated in Asia; Central Asia (Siberia). They
inhabit the slow moving and stagnant waters of rivers, lakes, ponds,
and ditches feeding on plants, detritus, small crustaceans, and insects.

For many years, it was believed that goldfish had originated from
the Crucian Carp Carassius carassius described by Linnaeus in 1758.

This fish has a wide range across the waters of the European
continent, running west to east from England to Russia, north to
Scandinavian countries in the Arctic Circle and as far south as the central France and the Black Sea.

However, recent genetic research points to C. gibelio as a more likely ancestor.

Goldfish were originally developed in China. By the 1500s, goldfish were traded to Japan, arriving in Europe in the 1600s and America in the 1800s.

The majority of the fancy goldfish were developed by Asian breeders.

We can see the results of this centuries-long endeavor in the
wonderful colors and shapes of goldfish today.

The Ranchu Goldfish is one of the older varieties of fancy goldfish. They originated in China, and in the later 1800s were further developed in Japan.

They are also known as the Buffalo-head Goldfish, especially in Asia.

Other common names of some of the Ranchu Fancy Goldfish
varieties are Red and White Ranchu Goldfish, Gold and White
Ranchu Goldfish, and Calico Ranchu Goldfish.

The Ranchu and all other dorsal-less fish resulted from
developments of this egg-shaped fish.

The Eggfish itself is not popular in the United States. Although it can be found in Asia, it is very rare in the US and would be expensive.

Today, domesticated goldfish are distributed world-wide, and the
Ranchu is one of more than 125 captive-bred fancy goldfish varieties.

  • Scientific Name: Carassius auratus auratus
  • Social Grouping: Groups – Can be kept singly or in groups
  • IUCN Red List: NE – Not Evaluated or not listed – There are no wild populations of this captive-bred variety.


The Ranchu Goldfish is an egg-shaped variety of goldfish. The body is short and stubby with short fins.

The Ranchu lacks a dorsal fin and will develop a fleshy ‘raspberry’ growth on the head.

The back is broad with a highly curved contour shape. The caudal (tail) fin splays out to the sides, often being almost horizontal, and may have three or four lobes.

Ranchu Goldfish will generally reach about 5 inches (13 cm), though
some aquarists report them growing much larger.

The average goldfish lifespan is 10 – 15 years, though living 20
years or more is not uncommon in well-maintained goldfish aquariums and ponds.

One of their most distinctive features is the head, which except for
its eyes, mouth, and nostrils, can become completely covered with fleshy growth.

The amount of head growth differs for each fish. Some can have so much growth that their vision is impeded while others may develop much less growth.

These fish come in a variety of colors but are most commonly
found bi-colored in gold/white or white/red and a calico, which in Japan is called Edonishiki.

They can also be a deep red overall, shaded overall in a reddish to yellow-orange, or have red scales edged in white.

They have also been known to be completely white or, in some cases, black.

  • Size of fish – inches: 5.0 inches (12.70 cm) – If kept in excellent conditions, this fish can grow to be larger than five inches; however, five inches is a good length for this fish to reach.
  • Lifespan: 15 years – The average goldfish lifespan is 10 – 15 years, but they have been known to live 20 years of more when well maintained.

Fish Keeping Difficulty

Ranchu Goldfish are some of the more delicate goldfish. Unlike the flat-bodied types of goldfish, they have a lower tolerance for pollution.

They will need good care and plenty of space. When it comes to feeding, they will not thrive with fast, competitive tankmates.

Many people will keep goldfish in an aquarium with no heater or filtration.

But for the best success in keeping goldfish, provide them the same
filtration, especially biological filtration, that other aquarium residents enjoy.

  • Aquarium Hardiness: Moderately Difficult – This fish is often highly inbred, leading to genetically weak specimens. The wen (the fleshy growth on its head) is very prone to infection. Ranchu Goldfish are generally considered to be among the less hardy of goldfish types.
  • Aquarist Experience Level: Intermediate – Ranchu Goldfish require a more experienced aquarist to maintain their rather delicate health.


Foods and Feeding

Since they are omnivorous, the Ranchu Goldfish will generally eat
all kinds of fresh, frozen, and flake foods.

To keep a good balance give them a high quality flake food everyday.

To care for your Ranchu Goldfish, feed brine shrimp (either live or
frozen), blood worms, Daphnia, or tubifex worms as a treat.

It is usually better to feed freeze-dried foods as opposed to live
foods to avoid parasites and bacterial infections that could be
present in live foods.

Due to their fleshy head growth they can have poor vision and a
harder time seeing their food, so need extra time to feed.


  • Diet Type: Omnivore
  • Flake Food: Yes
  • Tablet / Pellet: Yes
  • Live foods (fishes, shrimps, worms): Some of Diet
  • Vegetable Food: Some of Diet
  • Meaty Food: Some of Diet
  • Feeding Frequency: Several feedings per day

Aquarium Care

These goldfish need to be kept in a well-maintained tank with plenty of space and a proper diet.

Minimum tank size is 10 gallons, but make sure water changes are frequent in such a small tank.

Regular weekly water changes of 1/4 to 1/3 are strongly recommended to keep these fish healthy.

Snails can be added as they reduce the algae in the tank, helping to keep it clean.

Water Changes: Weekly – Goldfish produce more waste than most
other freshwater fish and benefit greatly from more frequent water changes.

Aquarium Setup

Setting up a goldfish aquarium in a manner that will keep your fish happy and healthy is the first step to success.

The shape and size of the aquarium is important and depends upon the number of goldfish you are going to keep.

These fish need a lot of oxygen and produce a lot of waste.

Good filtration, especially biological filtration, is very helpful in
maintaining the water quality of the aquarium.

A filtration system will remove much of the detritus, excess foods,
and waste, which keeps the tank clean and maintains the general health of the goldfish.

Tank parameters to consider when choosing a goldfish aquarium:

Tank size
Ten gallons is the absolute minimum required to house a Ranchu Goldfish.

It’s best to start with a 20 – 30 gallon tank for your first goldfish and
then increase the size of the tank by 10 gallons for each additional goldfish.

Providing a large amount of water per fish will help dilute the
amount of waste and reduce the number of water changes needed.

Tank Shape
Always provide the maximum amount of surface area. A large
surface area minimizes the possibility that the goldfish will suffer
from an oxygen shortage.

Surface area is determined by the shape of the tank. For example an elongated tank offers more surface area (and oxygen) than a tall tank.

Oval or round tanks that are wide in the middle and narrower
toward the top might be filled less than full to maximize the surface area.

Number of fish
For juveniles a general rule of thumb is 1 inch of fish (2.54 cm) per 1 gallon of water.

However, this rule only applies to young fish. Larger gold fish
consume much more oxygen than young fish so maintaining this
formula for growing fish will stunt them and could contribute to disease and even death.

Fish size and growth
To allow for proper growth, either buy fewer fish than the maximum number or be prepared to get a larger tank. To prevent stunted growth and other health problems, don’t overstock the aquarium.

Goldfish are a cold water fish and will do best at temperatures between 65 – 72° F (18°- 22° C).

Unlike the flat-bodied types of goldfish however, the Ranchu
Goldfish have a lower tolerance for pollution and cannot tolerate
temperatures much below 60° F (16° C).

Provide a gravel substrate to help create a natural and comfortable
environment for your fish.

You can add some decor, but make sure that all ornamentation is
smooth with no protruding points or sharp edges. Smooth rocks or driftwood should be used sparingly if at all.

Aquarium plants would be the best choice of aquarium decor for
goldfish, but unfortunately these fish are diggers.

Consequently live plants may be uprooted. Artificial plants make a good substitute and silk plants are safer than plastic ones.

Most aquariums come with a cover that includes lighting. A cover
for the tank is desirable as it reduces evaporation and though they
are not prone to jumping, on occasion some gold fish will jump out.

Lighting is not essential for goldfish, but does make the aquarium a
nice show piece and lighting will help if you have live plants.

Goldfish are freshwater fish, but they have some tolerance for slightly brackish water. The salinity level for C. auratus must be kept low, below 10% with a specific gravity of less than 1.002.

Minimum Tank Size: 10 gal (38 L) – Ten gallons is the absolute minimum required to house this fish.

It has high oxygen requirements, and produces a lot of waste. It will have very stunted growth if it is kept in a smaller aquarium.

Suitable for Nano Tank: Sometimes
Substrate Type: Any – A medium-sized gravel works best.
Lighting Needs: Moderate – normal lighting
Temperature: 65.0 to 72.0° F (18.3 to 22.2° C) – Goldfish are a cold water fish.

Unlike the flat-bodied types of goldfish however, the Ranchu
cannot tolerate temperatures much below 60° F (16° C).

Breeding Temperature: – In the wild, goldfish spawn in the spring
when water temperatures reach about 68° F (20° C).
Range ph: 6.0-8.0

Hardness Range: 5 – 19 dGH
Brackish: Sometimes – Goldfish are freshwater fish, but they have
some tolerance for slightly brackish water.

Any salinity for must be kept low, below 10%, a specific gravity of less than 1.002.
Water Movement: Moderate
Water Region: All – These fish will swim in all areas of the aquarium.
Social Behaviors

Goldfish are very social animals and thrive in a community. Not only are they a great community fish but they are great scavengers as well.

It is really not necessary to add other scavengers or other bottom
feeders to the aquarium when you have goldfish.

When choosing tankmates, keep in mind the physical traits of the Ranchu Goldfish.

Like the Lionhead Goldfish, Telescope Goldfish, and the Celestial
Goldfish, the Ranchu can be visually handicapped.

Further, its swimming ability is encumbered by its rounded body
and the lack of a stabilizing dorsal fin, a trait that is also seen in the Water-Bubble Eye Goldfish.

While the Ranchu cannot readily compete for food with fast
swimming types of goldfish, these similarly handicapped varieties can make good companions.

Venomous: No
Temperament: Peaceful
Compatible with:
Same species – conspecifics: Yes
Peaceful fish (): Safe
Semi-Aggressive (): Threat
Shrimps, Crabs, Snails: Safe – not aggressive
Plants: Threat – Goldfish will eat many kinds of aquatic plants. In their constant search for food, they can end up uprooting plants that they don’t eat.
Sex: Sexual differences

During the breeding season, the male has white prickles, called
breeding tubercles, on its gill covers and head.

Seen from above, a female will have a fatter appearance when she is carrying eggs.

It is impossible to sex Goldfish when they are young and not in
breeding season, but generally the male is smaller and more slender than the female.

Breeding / Reproduction

Ranchu Goldfish are egg layers that spawn readily in the right conditions.

They can be bred in groups as small as five individuals, but they are
very social animals and likely to breed in larger groups as well.

The only time Goldfish will spawn in the wild is when spring arrives.

To spawn them in the aquarium, you will need to mimic the conditions found in nature.

Provide an aquarium that is at least 20 gallons and make sure the fish are healthy and disease free.

Some breeders suggest you treat them for parasites. Many breeders
will also separate the males and females for a few weeks prior to
breeding to help increase their interest in spawning.

Introduce the fish into the breeding tank at the same time. The
tank will need a lush environment with solid surfaces for the
spawning process and for the eggs to adhere to.

Bushy, oxygenating plants, such as Anacharis, work well for this,
though artificial plants or fibrous spawning mops can also be used.

To induce spawning, the temperature can be slowly dropped to
around 60° F (11° C) and then slowly warmed at a rate of 3° F (2° C) per day until they spawn.

Spawning generally begins when the temperatures are between 68° and 74° F (20°- 23° C).

Feeding lots of high protein food such live brine shrimp and worms
during this time will also induce spawning.

Feed small amounts three times a day, but don’t overfeed. Uneaten scraps will sink to the bottom and foul the water. Maintain the breeding tank with partial water changes of up to about 20% per day.

Before spawning, as the temperature increases, the male will chase
the female around the aquarium in a non-aggressive way.

This can go on for several days, and the fish will intensify in color. During the spawn, the fish will gyrate from side to side, and the male will push the female against the plants. This stimulates the female to drop tiny eggs which the male will then fertilize. The eggs will adhere by sticky threads to the plants or spawn mop. Spawning can last two or three hours and can produce up to 10,000 eggs.

At this point the parents will start to eat as many eggs as they can find. For this reason, it is best to remove the parents after spawning is complete.

The fertilized eggs will hatch in 4 to 7 days, depending on the temperature.

You can feed the newly hatched goldfish specialty fry foods until
they become big enough to eat flake or brine shrimp, or you can
offer the same food as you feed the parents as long as it is crushed very small.

At first, the fry are a dark brown or black color in order to better hide and not be eaten by larger fish.

They gain their adult color after several months and can be put in
with larger fish once they reach about 1 inch long.

See Breeding Freshwater Fish – Goldfish for more information on breeding Goldfish.

Ease of Breeding: Moderate
Fish Diseases

In properly maintained goldfish aquariums or ponds, goldfish illness is largely preventable. Even so, goldfish illnesses can occur, and if left untreated, may prove fatal. Goldfish are hardy, though, and if treated in a timely manner, most will make a full recovery.

When treating individuals, it is usually best to move the afflicted
fish into a separate tank with no gravel or plants and do regular partial water changes.

However, if the disease is apparent throughout the main tank, it may be best to do the treatments there.

Whether treating in a hospital tank or your main tank, read and
follow the manufacturer’s instructions for any medication.

Some medications can adversely affect the water quality by destroying beneficial bacteria.

You may also need to remove the carbon from the filtration
system, as carbon will absorb many medications, making the treatment ineffective.

Goldfish diseases are mostly the same as those that afflict other
freshwater fish, and the symptoms and treatment of goldfish are also similar.

The main types of fish diseases include bacterial infections, fungal
infections, parasites, and protozoa.

There are also other ailments caused by injury, poor nutrition, or
bad water conditions.

One of the more common problems is Ich, which is a protozoan disease. Ich is easy to identify because your fish looks like it is sprinkled with salt. Though Ich is easily treated, like other protozoan diseases, it can be fatal if not caught quickly.

Some other protozoan diseases are Costia, which causes a
cloudiness of the skin, and Chilodonella, which will cause a blue-
white cloudiness on the skin.

External parasites are fairly common, too, but pretty easy to treat
and usually not fatal when treated.

These include flukes, which are flatworms about 1 mm long with hooks around their mouths.

They infest the gills or body of the fish. Another type of parasite is
fish lice (Argulus), flattened, mite-like crustaceans about 5 mm long
that attach themselves to the body of the goldfish.

Lastly, anchor worms look like threads coming out of the fish.

Some bacterial infections include Dropsy, an infection in the
kidneys that can be fatal if not treated quickly.

Fish Tuberculosis is indicated by the fish becoming emaciated (having a hollow belly). For this illness, there is no absolute treatment, and it can be fatal.

Tail/Fin Rot may also be bacterial, though the reduced tail or fins can be caused by a number of factors as well. There is also fungus, a fungal infection, and Black Spot or Black Ich, which is a parasitic infection.

Swim Bladder Disease is an ailment indicated by fish swimming in
abnormal patterns and having difficulty maintaining their balance
. This can be caused by a number of things: constipation, poor
nutrition, a physical deformity, or a parasitic infection.

Feeding frozen peas (defrosted) has been noted to help alleviate the
symptoms and correct the problem in some cases.

Other miscellaneous ailments include Cloudy Eye, which can be
caused by a variety of things ranging from poor nutrition, bad
water quality, and rough handling.

It can also be the result of other illnesses, such as bacterial infections.

Constipation is indicated by a loss of appetite and swelling of the
body, and the cause is almost always diet.

Then there are wounds and ulcers. Wounds can become infected, creating ulcers. Wounds can develop either bacterial or fungal infections, or both, and must be treated.

There are treatments for each of these diseases individually and
treatments that handle both.

illnesses, see Goldfish Care; Fancy Goldfish and Goldfish Diseases.


The Ranchu Goldfish is readily available in fish stores and online,
but it costs than most other varieties

How long do ranchu goldfish live?

Ranchu Goldfish will generally reach about 5 inches (13 cm), though
some aquarists report them growing much larger.

The average goldfish lifespan is 10 – 15 years, though living 20
years or more is not uncommon in well-maintained goldfish aquariums and ponds.

How big can ranchu grow?

Ranchu Goldfish will for the most part grow to about about 5
inches , though some aquarists report them growing as large as 8 inches. The Ranchu deep belly is about 3/4 the length of the fish.

How long does it take for fish to grow full size?

Small fish that get plenty of food can reach adult size in 12 weeks. Large species that struggle to feed and/or live in water that’s on the
cold side of what they cna tolerate can take several years to grow to their full size.

Types of Goldfish (goldfish breeds)

Undoubtedly the most widely kept of all fish, goldfish exist in a far wider range of colors than their name implies.

Goldfish are suitable for both home aquariums and ponds, although the different color forms vary in terms of
their hardiness and not all are suited to be kept outdoors all year in temperate areas.

Goldfish are members of the carp family, but unlike most fish in this group, they lack any barbels around the mouth.

This characteristic allows them to be distinguished at a glance from koi. you can check out this blog post about the difference between a koi vs goldfish

Hardy Goldfish Types goldfish breeds

A body shape that has an elongated flattened football shape include: the Common, the Comet, Shubunkin. (good breeds for an outdoor goldfish pond).

The common, comet and shubunkin look very similar in shape and colors.

The comet has longer fins and most notably its tail fin is much longer.

The common doesn’t come in calico but the comet and shubunkin do.

The shubunkin is only calico so if it’s calico with short fins, it can’t be a common.

common goldfish (Carassius auratus) can become tame in both pond and aquarium surroundings.

They may live for more than 40 years—far longer than most other pond and aquarium fish.

Common Goldfish This is not only the most popular goldfish variety, but also the hardest and potentially the largest.

It occurs in a range of colors, but solid (“self-colored”) fish are usually preferred.

Good specimens display body symmetry, with even curves on the upper and lower body.

A short, broad caudal peduncle and a wide, slightly forked caudal fin make common goldfish strong swimmers.

These fish can survive in frozen ponds for short periods provided the water is deep enough for them to avoid becoming trapped in the ice itself.

Common Goldfish These fish vary from yellow through bright orange to a deep blood-red.

In exceptional circumstances, they may reach over 24 in (60 cm) long.

comet goldfish
comet goldfish

This elegant variety originated in the United States during the late 1800s. It is distinguished by its slim, streamlined body and its deeply forked caudal fin, which should be longer than the body when fully extended.

Comets are usually variegated in color; the most popular variety is the Sarasa, which is easily recognizable by the
deep red-and-white patterning extending over the body and fins.

Comets are active by nature,and require a spacious aquarium if kept indoors.

They will thrive in pond surroundings, although they may prove vulnerable to fin congestion during periods of severe cold weather.

Comet The Comet’s caudal and dorsal fins are greatly enlarged. This individual displays some chocolate body patterning.

Sarasa Orange may replace the more common red color of these fish. The variegated patterning
differs widely among individuals.


common goldfish black color

The protective scles on a goldfish form part of the outer layer of the body known as the epidermis.

Beneath this is a layer called the dermis, which itself overlies layers of fat and muscle.

Distributed among these layers are the pigments that give goldfish their vibrant skin colors.

These include reddish-orange and yellow pigments known as lipochromes, and melanin, a black pigment.

Lipochromes usually occur in the upper layers, but the location of the black pigment is more variable.

If melanin is present just below the scales, the goldfish looks jet black; if located in the lower layers, the fish looks blue (for example, the Blue Pom-Pon, bottom right).

When both types of pigment are present in different layers, this creates chocolate or coppery shades.

A goldfish that completely lacks pigmentation is silvery in color.

Another factor influencing the appearance of goldfish is the presence in the dermis of cells known as iridocytes.

These cells are normally distributed over the entire body, giving goldfish, such as the Blue Pom-Pom, a
shiny appearance.

However, the upper iridocytes are missing in some goldfish varieties. In such cases, the lower level of cells has a direct effect

types of goldfish Blue Pom-pom

Goldfish are descended from carp that were kept in China about 1,700 years ago.

The first records of orange-marked carp date back to AD 300, but it was only from around AD 800, during the Sung Dynasty, that people started to breed these colorful cyprinids for ornamental purposes.

Goldfish feature
prominently in oriental literature and many other forms of art, including ceramics, and it is possible to track their early development from such sources.

Ancestral lines displaying many of the features seen in today’s varieties, including telescope-eyes, were well-established by 1600, as were numerous color variants, including some with variegated coloring.

The different body shapes and fin types that characterize many of the modern varieties were also beginning to emerge by the early 17th century.

Goldfish were imported to Japan in the 16th century, where still more varieties were bred, but it was to be another 200 years before they became available in the West.

They soon became highly sought-after, as the pond fish of first choice for the estates of the European aristocracy, and were kept in decorative bowls in grand houses.

Rather surprisingly, they did not reach North America until 1874. Nevertheless, their popularity grew so rapidly there that the first commercial goldfish breeding farm was established in the United States just 15 years later.

different types of goldfish

shubunkin goldfish
shubunkin goldfish

This popular variety is very close in appearance to the Common Goldfish.

This is especially so in the case of the London Shubunkin, which has an identical body, and differs only in terms of the arrangement of its iridocytes.

This particular variety was developed by London breeders during the 1920s, by which time enthusiasts in the U.S. had already created the long-tailed American Shubunkin.

In due course, the two varieties were crossed by breeders of the Bristol Aquarist Society in western England, creating the Bristol Shubunkin—a very distinctive and different form with large, flowing lobes on its caudal fin, which must not be allowed to droop.

Shubunkin coloration is generally very variable, but the orange areas tend to be paler than those of Common Goldfish.

They may also display dark speckling, as well as bluish shades that range from pale-whitish through to violet.

Darkly marked Shubunkins are highly attractive when seen at close range, but they are less conspicuous in ponds unless the water is particularly clear.

American Shubunkin The caudal fin lobes of this variety are much narrower than those of the Bristol Shubunkin;
they are tapering rather than rounded in shape.

Fancy Types of Goldfish goldfish breeds

An egg shape body shape are considered the fancy breeds and can include: Fantail, Ryukin, Veiltail, Oranda, Telescope,Black Moor, Panda Butterfly, Ranchu, lionhead, Pompon, Pearlscale, Hama Nishki, Celestial and Bubble-Eye.

The mature oranda, ranchu and lionhead has a wart like wen hood cover over its face and head

The oranda has a dorsal fin and the lionhead and most ranchu don’t.

The ranchu has a prominent arch in its back and downward pointed tail fins.

The lionhead and oranda have a straighter back line.

A goldfish with a hood cover with a straight back and no dorsal fin is a lionhead.

The fantail, ryukin and veiltail have similar egg shaped bodies with no distinct features like a hood cover or globe eyes

The fantail and ryukin have sturdy upright fins and tails.

The ryukin has a more prominent hump that the dorsal fin sits on than the fantail.

The veiltail has long flowing fins and tail.

The telescope, black moor and panda butterfly have their eyes on the sides of ball like protuberances

A black moor is a telescope/globe-eye but is only black or faded black in color.

The panda butterfly resembles the colors of a panda bear, clear sections of black and white.

The pearlscale and hama nishiki have a golf ball body shape with scales that stand out like little white domes

the hama nishiki has a slight hood cover on top of its head while the pearlscale does not.

The celestial has bulging eyes that point upward and no dorsal fin.

The bubble eye has two bubble shaped check pouches

types of goldfish pearlscale goldfish
pearlscale goldfish

pearlscale goldfish

This ancient Chinese variety can be identified by its rotund body, double caudal fins, and pearl-like markings on the sides of its body.

Each scale has a raised whitish center, making it look as if a pearl is embedded in it.

The variegated red-and-white form is the most common Pearlscale goldfish, but there is a also nacreous variety that resembles the Shubunkin in coloration.

Pearlscales goldfish are not strong swimmers, and are usually kept in aquariums rather than ponds, where their distinctive appearance is easier to appreciate.

ryukin goldfish

types of goldfish ryukin goldfish
ryukin goldfish


The most obvious feature of this goldfish is the hump between the dorsal fin and the head.

The body is relatively short and deep, the dorsal fin is tall, and the elongated caudal fin is divided to form a double tail.

Ryukins are generally brightly colored, with a deep-red and white coloration being the preferred form.

The markings on these goldfish should be symmetrical as far as possible.

Chocolate (coppery) individuals are often recognized as a separate form, the Tetsuonaga, especially in Japan.

Tetsuonagas have a reputation for both hardiness and the quality of their fin shape, so they are useful in Ryukin breeding.

The Ryukin is named after Japan’s Ryukyu Islands, where the ancestors of this goldfish were first introduced from China.

Orange-and-White Ryukin Ryukins have either normal eyes, as shown in this largely orange form, or, occasionally, telescope-eyes.

Calico Ryukin Nacreous patterning is not common in double-tailed goldfish but is seen in the Ryukin.

Calico Ryukins often have bold, contrasting markings.

wakin goldfish

types of goldfish wakin goldfish
wakin goldfish

This form displays a variegated pattern of orange and white body markings.

The vibrantly colored areas, which can vary from yellow through to reddish-orange, should extend around the body
so that the white areas do not predominate.

Purewhite wakin goldfish, which occasionally occur, are not favored by breeders.

Although the reflective metallic form is the most common, a nacreous variety also exists.

The wakin goldfish has a body shape similar to the Common Goldfish, but it can be instantly distinguished by its double caudal fin.wakin goldfish  are lively by nature, and grow rapidly; fish reared in ponds can reach 8 in (20 cm) in
length by three years of age.


jikin goldfish

Descended from Japanese Wakin stock, the Jikin is often known in the West as the Peacock Tail.

The raised upper lobes of its double caudal fin form an X-shape when viewed from behind.

The Jikin’s body should be mainly silvery, with red areas restricted to the fins and around the lips.

However, breeding Jikins with this desired arrangement of markings and a well-balanced caudal fin shape always proves difficult, even when the parent fish are both well-marked and from a long-established line.

Black Moor

types of goldfish black moor goldfish

The matt-black color of the Black Moor is highly distinctive, as is its corpulent body shape.

This goldfish is a telescope-eye variety, with eyes extending out from the sides of the head.

The Black Moor is a selective color form of the Veiltail Although developed in the UK, it is now kept worldwide.

These fish are not very hardy, and are better suited to an aquarium than an outdoor pond, especially through the winter (in temperate areas).

Their coloration makes for an attractive contrast with brightly colored goldfish.

lionhead goldfish

types of goldfish lionhead goldfish

The absence of a dorsal fin is a key feature of the Lionhead.

The result is a smooth back that curves gently to the double caudal fin, the curvature accentuated by the fish’s relatively long body.

As Lionheads grow older, they develop a distinctive hood that covers the entire head area.

The headgrowth or hood (also known as wen or crown) may be a prominent growth on the top of the head (cranial region) or may encase the whole head except for the eyes and mouth

This usually starts to become evident at the very top of the head, and takes several years to develop to its full extent, when it has a raspberry-like appearance.

The hood is more developed in this variety than in any other.

Lionheads exist in a wide range of colors, although solid colors such as orange are most commonly seen.

They do not thrive at high temperatures, nor are they hardy in temperate areas.

Blue Lionhead When fully grown, the hood should cover the entire head, encircling the eyes.

The head has a wide appearance when viewed from above.

Oranda goldfish

types of goldfish Oranda goldfish

The dorsal fin on the back of an Oranda allows it to be distinguished at a glance from other types of hooded goldfish.

The Oranda also has a longer body shape and is a more powerful swimmer.

The hood, or wen as it is called in Japan, is normally restricted to the top of the head, extending back over the eyes. In mature individuals, the area between the folds of the hood may appear whitish.

Although this can look like a sign of disease, it is actually an accumulation of the protective mucus produced by the fish’s body.

The coloration of these goldfish is sometimes unstable, just as it can be in other hooded varieties.

This is particularly true of blackand- orange individuals, in which the orange areas often become more
prominent over time.

Blue Oranda In this increasingly popular color variety, the underparts are usually a lighter shade.

Ranchu goldfish

 types of goldfish ranchu goldfish

Sporting a hood similar to the Lionhead’s, the Ranchu is the Japanese counterpart of that ancient Chinese breed.

The Ranchu can be differentiated from the Lionhead by its shorter, more steeply curved body.

As with Lionheads, not all Ranchus display smooth body curvature from head to tail, and an individual with slight humps along its back is considered to be seriously flawed.

The double caudal fin may be only partially divided. In Ranchus of the highest quality, the top edge of the caudal
fin should ideally form an angle of 90 degrees with the caudal peduncle.

Ranchus, which are also known as Buffaloheads, are the most popular Japanese goldfish.

Four principal founding lines are recognized, each of which is named after its creator.

The dominant variety is the Ishikawa lineage; the others are Sakuri, Uno, and Takahashi.

All these forms display a hood, but some less-common varieties lack this feature.

They include the Osaka Ranchu, named after its city of origin, which also has a more rounded body. Another hoodless variety is the Nankin Ranchu, from the Shimane area of Japan, a silvery-white fish with red gill covers, lips, and fins.

In addition, there is the rare Nacreous Ranchu, also called the Edonishiki, in which the hood is poorly developed.

Red-and-White Ranchu A mature individual with hood growth on the side of the face is described as okame (the
name of a Japanese theatrical mask indicating a fat girl).

Red Ranchu All the Ranchu’s fins are relatively short; the caudal fin is carried high. The hood has yet to develop in
the young specimen shown above.

 types of goldfish Veiltail goldfish

Veiltail goldfish

The elegant fins of the Veiltail are easily damaged,so this goldfish should be housed in a spacious aquarium—free from obstructions such as large rocks—rather than in a pond.

The long caudal fin of the Veiltail is fully divided, so that it hangs down in folds.

The dorsal fin is tall, and in a well-proportioned Veiltail it should match the height of the body.

The overall body shape of this variety is rounded rather than elongated.

The anal fin is paired and relatively long, and tends to flow vertically when the fish is swimming.

In addition to individuals with normal eyes, telescope-eye examples of this variety are not uncommon.

The breed was developed from Ryukin stock by American breeders around
Philadelphia in the late 1800s

Celestial goldfish names

Actual video of celestial eye golfish

types of goldfish celestial eye golfish side view

types of goldfish celestial eye goldfish

Selective breeding of the goldfish has brought into being numerous variations in eye shape.

The Celestial has eyes that protrude very obviously.

They are not on the sides of the head, as in most goldfish, but rather in a semihorizontal plane so  that they point upward, as if toward the stars (hence the name).

The fry hatch with a normal eye arrangement, but the eyes rotate and shift position soon afterward.

The bodies of these goldfish are relatively elongated, and they have slightly curved backs, with no dorsal fins.

Both metallic and nacreous forms of the Celestial exist.

bubble eye goldfish

This unmistakable variety is characterized by the presence of large, bubblelike sacs under its eyes.

As in the case of Celestials, Bubble-Eyes have a long body shape, lack a dorsal fin, and have a double caudal fin.

Symmetry is a very important feature of this variety, with the sacs ideally being equal in size and shape.

These fluid-filled sacs wobble when the fish swims, and become compressed when it searches for food on the floor of the aquarium.

In a good specimen, the combined width of the bubbles and head should match that of the body. Bubble-Eyes
are only suitable for aquarium surroundings.

The tank setup needs to minimize the risk that the fish will damage their bubbles and provide them with plenty of swimming space.

Rockwork should not be included, and plants should be restricted to the back and sides of the tank. If a sac is accidentally punctured, it is likely to deflate.

can guppies live with goldfish

No Once the goldfish get large enough, they’ll eat (most of) the guppies, unless there are sufficient places for the guppies to hide from the goldfish.

(This rule generalizes to “When one fish fits inside the mouth of another fish, the first fish gets eaten.”)

There are many tanks that contain plastic dividers to keep your fish separate. Most goldfish are kind of herbivores. Usually goldies are the things eaten by other things when they are small.

But if your goldfish gets big enough I’m not promising it won’t eat other fish, it just might… Goldfish will eat insect larva and occasionally other fish if they are big enough and the prey is small enough.

They eat crustaceans some small invertebrates and plant material frequently. Small fish fry are likely to be eaten if the Goldie is hungry.

Gold fish are a pretty peaceful tank fish. They have different dietary needs than many other fish, so make sure all fish in your tank have their dietary needs met.

types of goldfish that can live together

Goldfish are easy to care for and fun to watch. But it’s essential that you understand which types can live together.

Although goldfish are more social than tropical fish, you could have compatibility issues if you place different types of goldfish together.

The types of goldfish include flat-body and egg-shaped, such as fancy goldfish. Egg-shaped goldfish cannot live with flat-body goldfish.

Egg-shaped goldfish are slow swimmers, and many fancies have trouble seeing. Flat-body goldfish will consume all the food before the egg-shaped ones realize you dropped food in the aquarium.

Egg-shaped or fancy goldfish look round like eggs and have decorative, long fins. Some fancies have bulbous heads or eyes, like the celestial bubble-eye and the black moor. Flat-body goldfish have slim, streamlined bodies and swim quickly. They include the common goldfish and comets.

All types of goldfish can survive in an unheated, indoor aquarium.

All goldfish are social. However, flat-body goldfish may bully the egg-shaped fancies if the aquarium is too small and the fish are competing for space and food. learn more

goldfish types for ponds

The outdoor pond in your yard will let you observe your goldfish in a natural setting. In establishing and maintaining a goldfish pond, be aware that the aquatic habitat needs of goldfish species vary. Some are tolerant of temperature changes, others are not. Also, not all species make good pond mates: Some species do not swim well with others.

This slender-bodied fish featuring bright red and crisp white colors is not the most popular selection for outdoor ponds. This native of China grows up to 18 inches — pretty large for a pond goldfish. Today’s pet-store version of the wakin is a descendent of the Chinese gibel carp. He is a friendly fish who quickly begins to surface once he learns regular feeding times. He will overwinter provided you keep a hole allowing for the exchange of oxygen drilled through the ice. This is necessary because the fish does not hibernate. He is a fast swimmer: Best pond mates are shubunkin or comet goldfish.

Comet goldfish feature yellow, orange, red or white solid-colored bodies. They are highly hardy: They can survive for 10 to 15 years in outdoor ponds with water temperatures kept between 65 and 78 degrees Fahrenheit. They are a single-tail fish who grow 6 to 10 inches in length.

The shubunkin goldfish is a favorite with outdoor pond enthusiasts due to a flexible yet hearty appetite that readily accepts most food sources, with vegetable-based selections being more nutritious choices. This fish features attractive calico-style patterns with mixtures of red, brown, orange and yellow colors combined with black spots. A native of Japan, this fish is an excellent match for most goldfish species other than the telescope and the bubble-eye, who swim at much slower speeds.

Black Moor
As indicated by his namesake, the black moor sports black as his only coloring. But that does not mean his appearance is dull. Instead, his scales have a velvety look that glistens in the water — particularly when sunlight penetrates. His protruding eyes don’t offer the best vision. He is best off with other visually challenged species such as the telescope and the bubble-eye. Don’t place any sharp-edged decoration in the pond, as these can cut his eyes.

The fantail species is an acceptable yet slightly challenging choice for beginners. He is hardy and will tolerate a few missed feedings but not being left for extended periods in cold water. He needs to come inside during the winter in northern climates. This fish grows to 6 to 8 inches and lives up to 10 years.

The ryunkin was developed from the fantail and carries over many of his ancestor’s tolerant qualities: He isn’t a picky eater. He will consume nearly anything offered to him and even things such as aquarium plants that were not intended to be on the menu. These fish will live 10 to 15 years and grow 6 to 8 inches in length. His best pond mates are oranda, fantail or black moor goldfish. He should not be paired with single-tail varieties such as shubunkin or comet goldfish.

The oranda offers outdoor pond enthusiasts the best of both worlds: Color variety and a visually appealing body style. His coloration is a plethora of color options from red, black, calico, chocolate, deep blue and a red/white combination on either metallic or matte scales. His body features a hood or fleshy growth at the top of his head. This growth is not fully developed until he reaches 2 years of age. But once matured, the hood is his defining feature. He does not tolerate cold or dirty water conditions, making him a more challenging keeper. read further here https://animals.mom.me/varieties-goldfish-suitable-outdoor-ponds-4693.html

best goldfish food

There are so many different brands of goldfish food on the market, ranging from cans of dry food to packages of freeze-dried blood worms.

But be careful! Some brands use tons of cheap fillers in their goldfish food – fillers that don’t actually add real nutritional value. In the end, your goldfish is getting less nutrition with every bite!

Stay away.

While most commercial brands do strive to provide a balanced diet your goldfish need to stay healthy, the level of nutrients actually in goldfish food will vary. By simply looking at the ingredients on the back of the can, you can get a feel of how one brand compares with the next. And later, your goldfish will thank you with vibrant colors and years of entertainment.

To start with, there are several different types of food you can buy. Dry food (including flakes, pellets, sticks, and wafers) are the most used and marketed goldfish food available.

Dry Goldfish Food
Simply browse through the fish aisle at your local pet store, and you’ll see dozens of commercial goldfish food cans on display, most of which are dry food. Some are specially formulated to sink in the water, while others naturally float at the top of the aquarium.

Flakes are known to float at the water surface, while pellets often sink to the gravel below (though not always – you can buy pellets that float as well).

So which should you buy – floating flakes or sinking pellets?

Goldfish graze at both the top and bottom of the aquarium. Though, they do spend most of their time energetically sifting through the substrate for any tasty tidbits they might have missed. Unless your goldfish are sick or sensitive to buoyancy problems, both floating and sinking food will do just fine.

If you have sensitive fancy goldfish, I highly recommend soaking dry food before feeding. Dry food expands as it absorbs water. If your goldfish eats a pellet before it expands, intestines may get clogged. To make goldfish food easier to digest, simply fill a cup with aquarium water and soak the dry food for 5 to 10 seconds before feeding. Green veggies can also help digestion (we’ll talk more about these later).
Sick goldfish will usually only touch food that sinks to the bottom.

It’s always good to have sinking pellets on hand to make sure all of your fishy friends get a bite. Since floating dry food can cause goldfish to suck in packets of air, some fish hobbyists only offer their goldfish sinking pellets to avoid problems – like buoyancy and swim bladder issues (which fancy goldfish are especially prone to).

Floating dry food has its advantages though. Flakes and floating pellets are easier to manage. Since they can be quickly removed after the feeding period, they won’t accidentally get caught under rocks and pollute the water.

Ultimately the brand of goldfish food you choose is up to you. If you have trouble making up your mind, you can always feed your goldfish both floating flakes and sinking pellets (variety is always a good way to go). full article here

What kind of fish can live with goldfish?

Goldfish rarely prey on rosy barbs and live harmoniously with them.

If you have a large tank, loaches do well with goldfish because they
also thrive in cool water and grow too large to be considered prey. Zebra danios will cohabitate with common goldfish, but are too
small to be kept with fancy or larger varieties.

Can I put two goldfish in the same tank?

A goldfish tank needs AT THE MINIMUM 10 – 20 gallons per fish. Plus, bowls do not allow for filtration which is a MUST. In a bowl, a goldfish may live a max of a few years.

In a properly sized tank, they grow to be up to 12 inches long, not counting the fins!

What size tank do I need for 2 goldfish?

Recommended goldfish tank sizes: Fancy goldfish: 3 feet long and a
volume of at least 20 gallons for one goldfish.

If you plan to keep more than one goldfish in your tank then add an extra 10 gallons for each additional fish. Common goldfish: 4 feet long and a volume of at least 30 gallons

How many gallons does a goldfish need?

Too much amonia in a tank is deadly to fish. The rule most experts suggest is 20 gallons for one goldfish and 10 gallons more per other goldfish. I have a 40 gallon goldfish tank with only 3 fantail goldfish in it.
