Koi usually live around 20 or 30 years. The oldest Koi on record was named
Hanako. It purportedly lived to be about 226 years old.
It lived in a pond that was in a stable area (read low geologic
activity) and was passed down from generation to generation.

What is the oldest living koi fish?
226 Year Old Koi Carp ‘Hanako’ The oldest known fish (and indeed
one of the longest living vertebrate ever recorded) was a beautiful
scarlet coloured female Koi called ‘Hanako’ (pronunced hah-nah-koh; translated as ‘Flower Maid’).
butterfly koi fish has a long fin koi fish they are also called dragon carp.
They have elongated finnage the pectoral, caudal and pelvic fins.
They are high breed from the common carp,
cyprinus carpio including wide varieties of wild carp races with a
domesticated koi (” Nishikigoi”)
butterfly koi fish was breed in the mid-20th century as a result of an
effort to improve the hardiness of traditional koi fish.
Butterfly koi fish are breed by Japanese breeders who interbred the
wild Indonesian longfin river carp with traditional koi fish.
The resulting fish had longer fins, long barbells, pompom nostrils,
and were hardier than koi fish.
These were known in Japan as “onagaoi” or “hire naga goi”, or translated in English “long tail carp”.
It was Randy LeFever, the son of Wyatt LeFever, a noted koi fish
breeder was credited with suggesting they looked like butterflies, a
trait for which the breed is named.
They are also sometimes referred to as Dragon Koi fish.
For clarification, the word koi is wholly inaccurate for describing these fish;
Koi are, as dictated by the Japanese breeders, Nishikigoi,
butterfly koi fish have long-finned carp are Hirenagagoi.
The word koi has been given to these fish to increase their resale
value and popularity in garden centres and the like
Conformation – The ideal shape of a koi has been set by tradition to be generously oval.
By contrast, butterfly koi fish are naturally more slender.
This difference is amplified by the fact that traditional koi judging is
done from a top-down viewing angle.
Relationship of fin to body – The ratio of fin-to-body is an
important scoring criteria in nishikigoi competitions.
By design, longfin embody a ratio that exceeds the standards
applied to nishikigoi by 500 to 1000 percent.
butterfly koi types Pattern differences – Great energy has been
given to developing butterfly koi versions of
traditional koi patterns, (e.g. kohaku, sanke, showa, utsuri and ogon).
Butterfly koi, however, exhibit these patterns in a slightly different way.
How big do butterfly koi grow in a year?
Their barbels (whiskers) even grow long and can fork into elaborate designs.
Butterfly koi seem to lack some of the body size of regular koi,
but the overall fish can run as long as 36 to 40 inches in the right pond with plenty of food.
They are graceful and pleasant to watch swim.
How long does a butterfly koi live?
The short answer is they can live over 200 years.
The oldest known Koi was Hanako who lived to be 226 years.
But the reality is most Koi fish do not live anywhere close to that long.
A water garden can be an elaborate planting in and around a pond,
or something simple in a watertight container.
You can start small, with a hollowed-out stone that catches
rainwater, a watertight, patio-sized container or jump right in with
an in-ground pond with water lilies, fish and a fountain
Water quality refers to the chemical, physical, biological, and radiological characteristics of water.
It is a measure of the condition of water relative to the
requirements of one or more biotic species and or to any human need or purpose.

komei koshihara is the last owner of Hanako
The Life of Hanako Koi
While her initial place of spawning is not accurately documented,
in 1966, her last and final owner, Dr. Komei Koshihara revealed that
she spent most of her life in a quiet pond at the foot of Mt.
Ontake in a locality near Oppara, Higashi-Shirakawa Village, Kamo County.
According to the Koshihara, the ravine was carefully constructed by
his ancestors only keeping Hanako’s well-being in mind, a factor he
believes led to her thinking that she was fondly loved by and was part of the family.
Pure water perennially trickled down into the pond, allowing
ultimate favorable conditions for Hanako.

Just wanted to share my indoor cichlid pond if anyone is interested. The necessity arose when my Oscar started reaching 9″ and had officially outgrown his 40 gallon home. I had originally planned on setting up a 125 gallon aquarium, but after sketching some ideas out and talking to the Mrs, she gave me the okay to go ahead with the indoor pond. 😀 The pond itself is roughly 150 gallons and about 7ft long. The water return from the filter is in the narrow end, which creates a current that empties into what I call the pooling end. The idea was to simulate on a micro scale a stream emptying into a lake. The natural habit of the fish in the pond varies, and this way they can all come a little closer to “home.” The pond is inhabited by a 10″ Oscar named Ludo. With him are 2 female Jack Dempseys (both around 6-7″), a Firemouth Cichlid, a Firemouth x Convict hybrid, a small family of Convicts, and 5 Silver Dollars. rapidly growing varieties of koi—may grow to a length of 36 in (90 cm) by five years of age in this environment. Constructing an indoor pond is very similar to creating a pond outside ), but its location in the home must be carefully considered (see box, below).

Always consider the safety of your design , especially if young children are likely to visit. It is important to have an efficient filtration system in an indoor pond, to maintain the quality of the water; partial water changes are also necessary, because, unlike an outdoor pond, it will not be periodically flushed through with rainwater. Evaporation will reduce the water level, so you will need to top off the pond regularly with fresh, dechlorinated water. On to the build..! read the full article here small indoor fish pond

Koi ponds are increasing in popularity. While you can choose various types of fishes for such ponds, koi fish is one of the most popular ones to keep in ponds. Besides, koi ponds are known to add serene beauty to homes. These fishes are usually much easier to raise, even for kids. Thus, they are a preferred breed to other fish species. Despite of ease, you may have to keep check on their health. Moreover, you will have to make sure that the habitat is appropriate for their survival. Whether you plan to breed them for business, or as a hobby, you will need to check the following tips to stock koi carefully in their respective ponds.
Moderate temperature conditions
You may require at least 1000 gallons of water for a koi pond. Also, you may need hardy plants, rocks, and smooth gravel in such a pond. These fishes can tolerate cold temperature moderately, so the pond will need to be constructed in a place with suitable temperature. While this species is able to manage through cold winters briefly, you may still need to find ways to keep the pond temperature regulated for them to survive. Similarly, you may have to control the temperature in hot summers as well. If you can manage this, while keeping the water quality hygienic, these fishes can reach up to 8 inches in just the first year.
Companionship and care
Koi have a much longer life than goldfishes. You can expect these to survive up to an average life of thirty years. Some have been even reported to survive more than 200 years. Thus, you are going to have to take care of them properly so that they are with you for many years to come. You will find that koi love companionship. They prefer each other’s company. In addition, and will love it when people feed them.
Koi also need proper supply of oxygen. Therefore, you should think of installing a nice fountain or waterfall in the pond to keep the water oxygenated for the fishes. Lack of oxygen may also result in the increase in the growth of ammonia in the water. This happens when the fishes excrete, resulting in the water becoming more polluted. In summers, this activity increases. You do not want the water to lose its oxygen due to the presence of impurities. Also, if you have plans for listing yourself on directories, etc. for koi then you can visit Zoomthelist.Com.
Ensure a functional filter
You also need to provide proper filtration in the pond. Proper water conditions for a longer time will only work if you have an operational filter system installed in the pond. Good filtration will help you remove the waste from the water bodies much faster.
Remember to use such methods to improve the condition of water for your breeding koi fishes. These fishes can survive for a long time if they have ideal conditions. Follow these tips and get the best out of your koi ponds.

Koi fish have a very long history in Chinese and Japanese culture.
They were originally common carp and were later domesticated and bred to produce certain colors.
Chinese invaders brought koi to Japan, where the fish flourished.
Koi fish are prominent in the work of Japanese tattoo artists because of a long-standing legend of how the fish become dragons. Most of the meaning and symbolism behind the fish stems from this ancient legend.
How a Koi Became a Dragon

According to legend, any koi that is able to scale the waterfall known as “Dragon’s Gate” will be transformed into a dragon. | Source
According to Chinese and Japanese myth, there was once a giant school made up of thousands of koi fish swimming up the Yellow River in China. As they swam, they gained strength by pushing against the current.
However, on the Yellow River, there is a waterfall. Once the fish reached the waterfall, most turned back and just went with the current because it became too hard.
The ones who remained continued to try to reach the top of the waterfall. These koi kept trying for one hundred years. At last, one koi successfully leaped to the top of the waterfall.
To reward this dedicated koi, the gods turned it into a beautiful golden dragon.
The falls have become known as the “Dragon’s Gate.” And legend has it that to this day, any koi that has the strength and perseverance to complete to journey up Dragon’s Gate will become a heavenly dragon.
It is also said that if a koi is caught, it will await the cut of the knife without a quiver with the bravery of a Samurai warrior facing the sword in battle.

In Chinese and Japanese culture, the Koi fish has a deep history and symbolic meaning. They mark one of the rare instances of domesticated fish. Originally carp, they were bred for their rich colors.
Some believe, however, that long ago, they descended from dragons.
The story goes that once there was a huge school of fish made up of thousands of Koi swimming in the Yellow River in China. They went upriver, pushing against the current until they came to a waterfall. Many turned back, believing it was too difficult an obstacle.
Some koi, however, kept trying and trying to jump over it. They kept at it for hundreds of years until finally, one koi made it to the top. To reward his persistence and bravery, the gods of the river turned that fish into a golden dragon.
Today the waterfall is known as the dragon’s gate, and some believe that any fish that can jump it will still be transformed into a dragon.
When a koi fish is caught, it will not flop and try to flee. With the bravery of a samurai, it awaits the inevitable blade that will take its life.
Coupled with the ancient symbol of yin and yang—light and dark, balance in the universe—this tattoo is one of the most powerful and symbolic images known to man. People with this tattoo do not sit down and die, but remain persistent in all aspects of life. Win or lose, they stoically accept their fate as another turn of the wheel.

THE NATURE OF TOBI
Rain Garden Ornamentals
Anyone who breeds koi knows about tobi. In other species these are often called “shooters”.
They occur in goldfish spawns too. They are the fry that grow to juvenile size very quickly.
They are noted for eating their smaller siblings.
Most tobi koi do not have the refined characteristics the breeder is looking for, although some do.
I have never seen a good explanation of how and why tobi develop.
If anyone knows of an authoritative description, please let us know. Until then, I will give you my off-the-wall
theory about tobi.
I think tobi are hard to explain because there are two factors at work, genetics and blind luck.
Genetics: Koi and goldfish carry in their genetic code remnants of everything that come before.
A top-notch pair of gosanke or ranchu carries all the genetic material needed to make the ancestral common carp or crucian carp from which they were derived through selective breeding.
They also have all the genetic material needed to recreate the incremental steps in their evolution.
In the offspring from a pair of sanke you will find kohaku, higoi and perhaps even a magoi.
A group of ryukin offspring may include individuals with characteristics of wakin and common goldfish.
The more ancestral forms are always more hardy.
Left to their own devices and allowed to breed indiscriminately for many generations, a population of koi will revert
back to something resembling the ancestral common carp and goldfish will revert back to something resembling a crucian carp.
In a group of sibling fry, those with a more primitative genetic make-up will be just a little bit stronger and faster giving them a slight advantage when it comes time to eat or avoid a predator.
But, in the world of fish fry, a slight advantage can become amplified many fold.
There is a snowball effect. A fry that gets just a little bit bigger than its siblings is better able to
capture and compete for food so it grows faster.
The larger the size disparity, the bigger the advantage. So, over just a few weeks time an individual that is just slightly
larger than its siblings becomes ten times larger than its siblings.
At some point, the size disparity becomes so great that the larger individual can eat its siblings providing it
with a new limitless food supply.
The snow ball effect escalates. Blind Luck But, how can some tobi be excellent examples of highly refined koi or goldfish and show no signs of being a throw-back to an ancestral form?
I think it is because there is a blind luck factor at work as well.
Imagine a group of larvae which have absorbed their yolk sack and are ready to begin feeding.
Perhaps some arrive at this stage a few hours ahead of the rest because they were spawned first or their position on the spawning substrate was a fraction of a degree warmer then the rest, or because of some other factor.
The larvae instinctively dart at a moving food particle.
Some times they catch it and sometimes they miss.
They are growing extremely rapidly and catching one or two extra choice food morsels can make a difference in that growth rate.
Some individuals are just lucky and are able to get a tiny bit ahead of their siblings.
As described above, a very small advantage can quickly snowball into a large advantage.
An individual with no innate genetic advantage can become a tobi just through bind luck.
Another Observation In some batches of fry the size distribution is large and there is an unusually large number of tobi.
In other batches the size distribution is narrow and the siblings look almost identical.
In general, the better the fry are fed the less variation there will be in their size.
If abundant live food can be kept in front of the fry at all times while maintaining good water quality, there is a much lower incidence of tobi.
Under the best of conditions the growth of fry is phenomenal and most of the population (except for those with serious deformities) has the potential to grow at the rate of tobi.
The best way to minimize the number of tobi is to provide better nutrition and husbandry.
The biggest and best koi and goldfish will have had the best nutrition and water quality their entire lives.
Periods of less than optimal conditions can have long-term effects.
In extreme cases, we say that the fish is stunted.
The younger the fish, the more severe and lasting the effect of poor nutrition and water quality.
Tobi are considered by most to be undesirables.
If they are genetic throw-backs then they probably are undesirable. However, you should be on the look-out for those fish
which have both the genetic potential to meet your selection criteria and the good luck to have gotten off to a fast start in life and become a tobi.
It is always a good idea to separate tobi if you can; especially if they have become large enough to be cannibals.
But, do not automatically assume they have no potential.
So, you’ve decided you want a koi pond in your backyard. Congratulations, it’s a great decision. Ponds aren’t just for keeping fish such as koi in, but they can also encourage other nature into your garden, provide a stunning focal point for visitors to admire and offer a source of relaxation – who doesn’t love closing their eyes and hearing nothing but the sound of trickling water as your very own pond babbles away not far from your back door?
With the decision taken to construct a pond, the big question is, what is your pond going to look like and where in your backyard is it going to go? Here are the factors you need to consider when designing a pond.
Decide on the style of your pond
When her home in West Village, New York needed a refresh, actress Julianne Moore hired professional landscaper Brian Sawyer to redesign her garden. Thankfully, you don’t need to source a professional with a Guaranteed Scholarships in Garden Design to help you decide on the style of your pond. When it comes to a pond housing fish, the most common designs are a formal shape, raised up and near to the house so that you can see your fish swimming around in all their splendor.
Consider the safety aspects
Arguably the most important factor to consider when it comes to designing a pond is the safety aspect. We’ve all read horror stories about young children accidentally walking or falling into ponds with terrible consequences. A raised pond can prevent that happening by providing a physical barrier between child and water. It also offers an edge to sit on, which can be handy if you want to relax in the garden or if the pond is for somebody elderly who may need to sit down while working on the pond. If you are still worried about the potential of a child falling in, then you can purchase a pond cover or netting. This will also protect your fish from any urban animals that may see them as an easy lunch.
Think about the electricity supply
Most likely, your pond is going to require a filter and pump while many of us will also want to install fountains or waterfalls. All of these require electricity to work. That can have a bearing on the positioning of your koi pond, as you are going to need it to be relatively close to a mains supply, which will probably come from a building. You should always use and consult a qualified electrician, especially when dealing with electricity and water.
Check the positioning of underground services
Your pond is going to require at least some digging down, so you need to check that it isn’t going to be situated above any water pipes, sewage pipes of electric cables. The last thing you want when you start constructing it is to cut through any of those three utilities.
Avoid siting your pond in the shade
There are several reasons for avoiding putting your koi pond in the shade. The most obvious is that if it is situated under trees, then come fall it’s going to fill up with fallen leaves which will be a nightmare to remove. If you want flowers to bloom among the water, then you’ll need to choose a position which receives sunlight for around six hours a day.
Metronidazole is an antibiotic (for anaerobic bacteria) and anti-protozoal medication used to treat various conditions internally and externally in fish.
As for Anaerobic bacteria, these are bacterium that thrive in environments in which there is little oxygen (anaerobic environments) and can cause disease in such environments as the intestinal tract and liver.
Metronidazole belongs to a class of antibiotics known as nitroimidazoles which work by ceasing the growth of bacteria and protozoa.
Metronidazole works by selectively blocking some of the functions within the bacterial cells and some parasites resulting in their death.
Metronidazole is metabolized in the liver (whether a fish or a human).
Metronidazoles primary use is for the treatment of ANAEROBIC gram positive & SOME negative bacteria including those that produce beta-lactamase.
However, it is not effective against aerobic bacterium. This means Metronidazole is a poor choice for suspected
bacterial diseases in open heavily oxygenated aquariums/ponds such as Columnaris,
while it is an excellent choice for diseases of the low/no oxygen environment of the intestinal tract or other internal
suspected bacterial pathogens (generally used ina fish food soak for best results).
Metronidazole may be a good choice for any bacterial disease present in low oxygen, high bio-load aquariums or ponds.
As well Metronidazole is effective for some protozoa.
It was originally found effective for the management of infection caused by Trichomonas vaginalis.
For fish applications Metronidazole has been shown to be in particular more effective for internal and external flagellates.
Metronidazole is also sometimes effective for other protozoan parasite infections, especially for
Cryptocaryon in marine aquaria as well as Hexamita & Ichthyophthirius.
Metronidazole is often recommended for disease in Cichlids which is often thought to be caused by Hexamita,
HOWEVER there is considerable evidence that the cause of “Hole in the Head” is simply the lack of Calcium and even positive calcium ions.
This is especially common in aquariums utilizing water softened using sodium chloride or potassium chloride to drive out hard water minerals.
Use of such water should be ceased prior to using Metronidazole and as well, the use of products such as Wonder
Shells mineral blocks should also be used first before treating with Metronidazole (or combined).
Due to Metronidazoles effectiveness against anaerobic bacteria by selectively blocking some of the cell functions of
anaerobic bacteria, Metronidazole along with Neomycin is a good choice for bloating of the digestive tract (common in goldfish).
Metronidazole selectively blocks some of the cell functions in anaerobic bacteria, resulting in their demise.
Metronidazole is also effective used in combination (such as with Praziquantel) or by itself for internal parasites such as Nematodes or Trematodes.
In marine aquarium infections is where Metronidazole really shines as it is very effective internally and since Marine
fish are always drinking the water around them, medication is easily transported to the infected area.
In Freshwater, treatment can be improved by soaking food as well and this is still an effective freshwater treatment as well.
7 days is a minimum treatment time indicated by the author. Instructions for treating with Metro for Hexamita
typically suggest 7-10 days, and if you read National Fish Pharmacy instructions for their Metro, they indicate 10 days period, nothing less.
Instructions vary and most instructions for treating with Metro indicate repeating dose every 24 hours with a 25% water change before treatment.
Part of the reason for the water change is to help reduce the flagellites that are expelled in the feces into the water.
A study at the University of Florida on Hexamita in Angelfish and treatment methods showed daily 25% water changes were almost as effective at reducing the amount of Hexamita in the intestines of affected fish as the metro.
2. ups battery backup (UPS) to run your regular air pumps.
An uninterruptible power supply (UPS) can also carry your pond through a brief power outage.
They are available at most office supply or computer retail stores.
The UPS works by providing the necessary current via a battery.
The battery remains charged by being plugged into the wall outlet.
This means that your pond will not flinch even a little bit when the power goes off, as it is will not be powered by line electricity.
The UPS will last longer if used to power small pumps or air pumps with low current consumption.
The larger circulation pumps will usually run only a few minutes.
3.Finally, if you live in an area where power outages are more common, you may want to consider a gasoline-powered generator.
The downside to generators is that they can be expensive, noisy, and rather heavy.
However, they can keep your pond (and also your home appliances) going throughout an extended power outage.
An important safety tip: DO NOT feed your koi fish during a power outage unless it is absolutely necessary, as it will cause pollutants and algae to build up faster. Most fish can go 5 to 7 days without being fed.
4.Tap water-Ancost-effectiveective way is to let your tap water to run continuously until the electricity is back on. Only thing is to monitor the chlorine level from time to time. Add the anti-chlorine as desired. I did this twice, and no problems with the fishes
5.Treating Ponds With Hydrogen Peroxide
Measure the length, width, maximum depth and average depth of the pond in feet. You will use these measurements to find the volume of the pond.
Calculate the volume of the koi pond using an online tool such as pond calculator. This calculator can also determine a recommended pump size and how many fish the pond can safely support.
Apply 1/2 cup of 3 percent hydrogen peroxide solution per 100 gallons of koi pond water to increase the oxygen content.
The peroxide will take effect within an hour, and the increased oxygen will last for about four hours.
Add 1/2 cup 3 percent hydrogen peroxide solution per 625 gallons of pond water when using peroxide after a potassium permanganate treatment.
It will take about an hour for the water to clear.
Things You Will Need

3 percent hydrogen peroxide solution
If you use hydrogen peroxide in the midst of a potassium permanganate treatment, wait three to four days before resuming treatment.
Hydrogen peroxide can cause gill damage if applied directly to koi.
Pour peroxide into the pond away from the fish, so it is diluted by the time it reaches them.
Use of hydrogen peroxide to increase oxygen levels is only a temporary solution.
Continual use can damage the koi’s gills.
55. Eliminate Algae from Your Aquarium
Home aquariums not only bring beauty to your home décor but can offer you therapeutic benefits as well.
The only downside is having to clean the fish tanks, especially when
algae begins to accumulate.
To clean your fish tank, safely and efficiently, without causing harm
to the inhabitants, is to use hydrogen peroxide.
To keep your fish and plants from being hurt, you want to only use
about 60 milliliters of three percent peroxide per 66 gallons of water.
Slowly add the peroxide to the tank using a syringe or dropper for five minutes. If you can, try and apply it directly to the algae. It will react with the algae, killing it, and then diluting.
56. Help Transport Fish
If you are transporting fish in a bag, adding hydrogen peroxide to
the water will help keep your fish more comfortable and safer during the carriage.
For this, you want to use the little white tablets that dissolve in
Well this depends on a lot variables. I also don’t know what you mean by pump… water pump or an air pump?
If we are talking about air then you need to consider many variables.
The volume of water, the size of the fish, the temperature of the water, the quality of the air above the water.
You really need to know more to answer this question. In a pond without an air pump if it were large enough you many never need an air pump.
If your fish were in a bag with pure O2 then it depends on the temp, stress and size of the animal.
Again not sure what type of “Pump” you are thinking of – water movement or air… but either way there are a lot of variables that had to be thought of before answering this question.
A pump will pull water and then push it through a filter of some sort and return it to the pond. If at the return it splashes then it will oxygenate the water.
Two thing occur here -oxygenation of the water and improved water quality.
The chemistry of water quality is complex and it’s balance is necessary for fish to be healthy. A filter – pump- is necessary to achieve that.
Oxygen in the water it also critical for the fish to survive. Constant
disruption of the water surface via water return to the pond from
the filter or by air stones is also critical for the fish to find oxygen in
their water and also to assist is balance of the water chemistry
So how long can they survive without oxygenated water and balance? Easy – until a ph crash caused by high levels of resultant
ammonia, nitrite and nitrate which will happen without a pump to run a filter. A ph crash kills fish overnight.
How to Keep Your Aquarium Fish Alive During A Power Outage
There are easy steps you can take to keep fish alive in a blackout.
Fortunately, for most of us, the worst result of bad weather is a short power outage.
It’s inconvenient for us but is perhaps more serious for aquarium
fish because they depend on filtration, aeration and heat from
devices powered by electricity.
The climate zone you live in and time of year also affect the welfare of your fish while the power is off.
There are ways to help prevent or reduce fish loss during and after these storms with a little planning.

The two most important considerations for your aquarium are temperature and dissolved oxygen.
The goal is to prevent a significant shift in temperature and to
maintain enough dissolved oxygen in the water to sustain the fish.
By far, the best option is to have a generator powerful enough to run all of the aquarium’s equipment.
Of course, the cost of a generator has to be weighed against the cost
of completely replacing all of the animals in your aquarium, many
of which may have reached adulthood during their time in your tank.
Keeping Aquarium Fish Alive During a Power Outage or Other Disaster
Fish Tank Temperatures During the Summer
For most people, the alternative is some towels, sheets of styrofoam
and one of those handy battery-operated air pumps often available
in aquarium stores or tackle and bait shops.
Other things to have on hand are extra airstones, air line tubing and batteries. A flashlight with fresh batteries will be needed, as will test
kits to monitor water quality for the duration of the power outage.
Your husbandry skills can have a significant impact on how well your fish survive a power outage.
Maintaining a successful
aquarium involves proper stocking levels, regular filter
maintenance, water changes and water quality testing.
By keeping fewer fish, both the decline in dissolved oxygen and the
rise in toxic ammonia will be slower when the filtration system is not running.
If water quality and chemistry (such as ammonia, nitrite and pH)
are correct, you don’t have to worry about water quality immediately after a power outage. read more

koi pond plants not only look beautiful but can also serve to keep algae at bay. As a koi pond owner, you will probably also take pride in its appearance and upkeep, and if you have been searching for tips on the right kinds of plants for your koi pond, you have come to the right place! Discover which plants are safe to place in your pond, and how to introduce plants into a koi pond that has previously been plant-free. Here, you will also get some terrific tips about which plants to feature in your pond, and what you need to ensure your chosen plants will thrive.
Maintaining the quality of your koi pond
If you are contemplating introducing a koi pond to your garden, you must be aware that the one of the most essential elements of caring for your koi is maintaining the pH levels in the water. Koi require an alkaline environment, with pH levels of 7.5 to 8. Any reading below 7 is dangerous and the levels will need to be raised. You should check the pH levels regularly using a pH testing kit. It is also advisable to test the area around the pond and you can find the Best Soil pH Tester at Backtofarm.Com. Should you find the pH levels to be too low you can remedy this by taking bucket of pond water and dissolving 1 teaspoon of baking soda per 5 to 10 gallons of pond water. Add this solution to the pond. Once the levels are correct, you are ready to introduce plants to your pond.
Introducing plants to your koi pond
As you may already be aware koi are likely to attempt to eat ay plants they can reach, and so you need to be cunning in the way you introduce plants to the pond. One method is to grow plants on a plant shelf, away from the hungry mouths of koi, however these shelves may provide predators with a handy step which they will use to catch and eat the koi. An alternative is to place plants directly into, or onto the water.
There are three main types of water plants for ponds you can introduce to your koi pond: floating, submerged, and shallow-water marsh plants. An attractive plant you may consider is the floating Water Hyacinth which provides many benefits including a natural filtration system, removing excess nutrients from the water. A floating plant such as the Water Hyacinth also blocks out light meaning algae will be less likely to grow in your pond. Yet, there are some downsides to selecting a Water Hyacinth, as your koi may decide to nibble on this easily accessible plant.
This plant resides in the shallow-water marsh plant category an is an attractive addition to a koi pond border. As you may have guessed from the name, the Umbrella Palm is shaped like an umbrella with several long leaves protruding from an extended stalk. This plant can thrive in warmer climates, but will need to be taken indoors if colder weather ensues.
American Waterweed (Elodea)
This wonderful plant is completely submerged but for the white flowers it produces which lie at the surface of the pond. The Elodea can be a great provider of shelter for smaller koi, and is perfect for utilising any excess carbon dioxide in the water. You will need to keep an eye on this plant however, as it can grow excessively, and is dangerous if allowed to infiltrate public waterways.
