Four Common Betta Fish Diseases

There are various diseases that can affect your betta.   Most betta fish diseases are caused by poor water quality, so you can prevent many by keeping the water clean.   Some of the most common illnesses include fin rot, velvet, and popeye.   This article will discuss some of these illnesses.

Fin Rot

Fin rot is one of the most common diseases.   If you keep a betta long enough, you will probably have to deal with it at least once.   This condition is characterized by the tail or fins rotting away.   It can quickly become a problem if you allow the water to stay unclean too long.   Although the tail or fins will grow back once treatment begins, it will take some time.  


Popeye is also one of the most common betta fish diseases.   Like fin rot, it's caused by unclean water which leads to a bacterial infection.   This condition is quite easy to spot as your fish's eyes will literally bulge out of his head.   It can be disgusting the first time you see it.   Popeye needs to be treated with antibiotics and frequent water changes.


Unlike the two aforementioned diseases, velvet is caused by a parasite.   It is highly contagious and can quickly spread to other fish in the tank.   Affected fish will attempt to get rid of the parasite by rubbing themselves against hard objects.   Other signs of velvet include rapid gill movement, weight loss, loss of appetite, and lethargy.

This illness presents a problem because it's usually diagnosed in an advanced stage.   Therefore, you would need to start treatment as quickly as possible.   TO treat this condition, you will need to dim the lights, add copper sulphate to the water, and raise the temperature to 80 degrees Fahrenheit.   Your fish may also have a hard time breathing.   Aquarium salt will help remedy this.


Dropsy is one of the most serious betta fish diseases.   It is usually fatal.   This illness results from kidney failure which causes fluid to build-up inside your fish.   You can easily spot his swollen belly.   If he also has raised scales, it's a pretty safe bet that he has dropsy.   Unfortunately, there is no cure and most bettas die within a couple of weeks.

These are some of the most common betta fish diseases. If you're new to caring for bettas , there are many more things you need to learn. So, click here to learn everything you need to know like dealing with bloated betta fish .
