4 Common Diseases In Betta Fish Betta fish, also known as Siamese fighting fish, are a popular species of freshwater fish that are often kept as pets due to their vibrant colors and unique behavior. However, despite their popularity, betta fish are prone to a variety of diseases that can significantly impact their health and well-being. In this blog post, we will explore four common diseases that betta fish are susceptible to: Fin Rot, Ich, Columnaris, and Velvet.

Fin Rot is a bacterial infection that causes the fins and tail of the fish to become frayed and discolored. This can be caused by poor water quality, injuries, or a weakened immune system. Ich, also known as White Spot Disease, is a parasitic infection that causes small white spots to appear on the fish’s body. Columnaris, also known as Cotton Wool Disease, is a bacterial infection that causes cotton-like growths on the fish’s body and mouth. Velvet is a parasitic infection that causes the fish’s body to become covered in a dust-like golden or copper-colored film.

All of these diseases can be serious if left untreated, and can lead to the death of the fish. It is important for betta fish owners to be aware of the signs and symptoms of these diseases, as well as the proper treatment methods, in order to ensure the health and well-being of their fish. In this blog post, we will delve deeper into these common betta fish diseases, including causes, symptoms, prevention and treatment methods. By the end of this post, you’ll have a better understanding of how to keep your betta fish healthy and happy.

Betta fish are usually taken care of as pets within the home or office. Over their two to three-year lifespan, with the exception of some betta fish living longer than they should, you may see them falling ill suddenly.

A betta fish can experience health conditions. Fortunately, such health problems can be avoided and addressed by pet owners. Alongside proper betta fish care, identifying and treating the infection must be prioritized, especially if it happens within the aquarium.

If you’re curious about some of the common diseases in betta fish, continue reading to learn about them.

  1. Fin Rot

Fin rot is an infection of the fins of betta fish. At first look, the betta fish’s fins may manifest signs of damage, which might be the reason for the infection. 

However, tails, mouths, and fins decay and decompose as time goes by. If an infection isn’t noticeable, it’s difficult to detect fin rot.

Fin rot is often caused by an unhealthy water environment that stresses the fish and minimizes their immune system’s capability to fight diseases. If left unaddressed, fin rot infection will go throughout the betta’s body, eventually leading to death.

Treatment for this includes replacing the water in the aquarium and tetracycline for its initial bacterial infection and antifungal medication to avert the possibility of a secondary infection.

Likewise, you can read some articles online so you can detect fin rot properly.

  1. Columnaris

This bacterial disease results in ragged and frayed betta fish fins. It also causes lesions and skin ulcers, gills discoloration, cottony growth on the mouth, fins, and scales, and white spots or marks on the mouth. There can also be challenges with how the betta breathes due to gill damage and infection.

You can avert the possibility of this bacterial disease by tending to fungal infections and open wounds. You can also avoid things like water hardness, overcrowding of fish in the aquarium, and limited oxygen to prevent columnaris. Moreover, you can place Indian almond leaves in their aquarium to provide antibacterial and antifungal compounds.

Note that columnaris can also be treated by using oxytetracycline and antibiotics. However, if the fish with columnaris is left on its own, it can die in less than 72 hours.

  1. Dropsy

Dropsy is usually noticed in betta fish and is generally deadly. It is more often contracted by using live food to feed the betta fish. There is not much information on what dropsy is about other than that it comes from using contaminated food.

A betta fish with dropsy will present itself with raised scales caused by a buildup of liquid beneath the fish’s scales. The fluid buildup is the outcome of kidney failure, and like any animal, once the betta fish’s kidney fails, it will lead to death.

Likewise, the bacteria that result in dropsy are infectious. It also leads to kidney failure for the betta fish. 

Assessing if your fish has dropsy is comparably easy. Your fish will have bloated scales similar to pine cones. The betta might also present itself with an enlarged stomach.

So far, there’s no known cure for dropsy, but an excellent way to minimize its chance of happening to your betta is to avoid using worms as food for them. It’s also crucial to keep your betta away from other fish if you believe it already has dropsy.

  1. Fish Fungus

The betta with this disease often has cotton-like growths, slime (mucus-like discharge), white lumps and bumps on the skin, and white fuzz films.

You can limit the probability of your betta having this by preventing primary injuries and infections in them and keeping their aquarium clean. You can do this by constantly changing the conditioner and water.

If your fish has a fish fungus already, then it’s ideal that you separate the fish into an individual hospital tank. You can quarantine the sick fish there and use medications designed to treat fish fungus.

Besides, this fungal infection can be deadly if your fish isn’t treated immediately.
