Betta fish, also known as Siamese fighting fish, are popular aquarium pets due to their vibrant colors and beautiful fins. While these fish are generally hardy, they are not immune to diseases. In this article, we will discuss four common diseases in betta fish and how to prevent and treat them.
- Fin Rot
Fin rot is a bacterial infection that can affect both the fins and the body of betta fish. Symptoms include frayed or torn fins, white edges on the fins, and red streaks on the body. The infection is caused by poor water conditions, such as high levels of ammonia or nitrite, and can also be caused by stress.
To prevent fin rot, it is important to maintain good water quality by doing regular water changes and keeping the aquarium clean. If your betta fish does contract fin rot, treat it with an antibiotic medication and improve the water quality.
- Ich
Ich, also known as white spot disease, is a parasitic infection that appears as small white dots on the fins and body of betta fish. It is caused by the Ichthyophthirius multifiliis parasite, which can be introduced to the aquarium by new fish or contaminated equipment.
To prevent ich, quarantine new fish before adding them to the main tank and regularly clean and sterilize aquarium equipment. If your betta fish does contract ich, treat it with a medication that targets the parasite and improve the water quality.
- Dropsy
Dropsy is a bacterial infection that causes the betta fish to swell and have a bloated appearance. Other symptoms include lethargy, loss of appetite, and protruding scales. Dropsy is caused by poor water quality, stress, or an underlying health issue.
To prevent dropsy, maintain good water quality and provide a stress-free environment for your betta fish. If your betta fish does contract dropsy, it is important to isolate it from other fish and treat it with an antibiotic medication.
- Velvet
Velvet is a parasitic infection that appears as a gold or rust-colored dust on the fins and body of betta fish. It is caused by the Piscinoodinium pillulare parasite, which can be introduced to the aquarium by new fish or contaminated equipment.
To prevent velvet, quarantine new fish before adding them to the main tank and regularly clean and sterilize aquarium equipment. If your betta fish does contract velvet, treat it with a medication that targets the parasite and improve the water quality.
In conclusion, betta fish are susceptible to several common diseases, but with proper care and attention, these diseases can be prevented or treated. It is important to maintain good water quality, provide a stress-free environment, and isolate and treat any sick fish promptly to ensure the health and longevity of your betta fish.

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.
- 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.
- 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.
- 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.
- 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.
Wrapping Up
Betta fish are easy to care for as they easily adapt to various tank conditions, but like other animals, they could get sick and suffer from bacterial and fungal infections. Luckily, such health issues can be prevented and addressed.
Your betta fish can be infected and have fin rot, columnaris, dropsy, and fish fungus while in your care. However, rest assured that knowing what type of disease your fish has is a step to knowing how to treat them and a chance to learn how to take care of them when they’re ill.
