Common betta fish diseases

Like other species of fish, betta fish also suffer from a multitude of diseases. However, most of these conditions are easily identifiable and can be treated if detected early. It is important to note that most of these illnesses arise from inadequate care and contaminated water. Common diseases include:

Dropsy

Dropsy is a rare but deadly disease that often causes kidney failure in betta fish. Fish that have this disease exhibit bloating of the abdomen due to fluid retention. Other symptoms include protruding scales, pale feces, and sunken eyes. The disease is contagious, and it is therefore important to isolate fish that exhibit early signs and symptoms.

Common causes of the disease include stress, a dip in water temperature as well as dirty aquarium water. Unfortunately, there is no known treatment for dropsy. However, it is advisable to have your betta fish euthanized to ensure they don’t contract the disease.

Pop Eye

Popeye is a common bacterial infection which is characterized by swelling and protrusion of one or both eyes. The good news is that the condition is treatable and fish can fully recover if treatment is administered early. Pop Eye can be prevented by frequently changing the water in your aquarium. If that does not work, you may have to purchase antibiotics such as Tetracycline to suppress the symptoms.

Fin and tail rot

Fin and tail rot is a condition that is caused by bacterial or fungi infection. The disease usually starts at the fins and tail end of the fish after which it slowly progresses to other body parts. The condition can arise due to injury or stress when betta fish fight. A dirty or overcrowded aquarium also increases the chances of fish contracting this disease. With the right treatment, fish have a high probability of making a full recovery; however, the fins and tails may not be as colorful as they were before.

Eye Cloud

Also known as the cloudy cornea, this condition is characterized by white films forming in the eyes. Though not fatal, if left untreated it can lead to loss of sight. Eye Cloud occurs when the water in your aquarium is dirty. You can prevent this disease by conditioning the water in your aquarium. If that doesn’t work, you can look to antibiotics such as Fungus clear and Metafix.

Fungal infection

Fungal infection is one of the most common ailments in betta fish. It occurs when previous infections damage the mucus or slime coating in the fish. Fish that contract this disease will exhibit cotton-like growths on the fins and skin. They will also be pale in color and exhibit disinterest in food. This infection is highly contagious and can be fatal if left untreated. Fungus clear and Mercurochrome are some of the antibiotics used to treat this sickness.

Columnaris

Columnaris is a condition that causes the discoloration of the gills, scales, and fins as well as whitish spots on the mouth. The condition is highly contagious hence the need to isolate infected fish. The disease can be prevented by regularly cleaning your betta fish tank and by not overcrowding the fish.
