Common Betta Fish Diseases

Betta fish can fall ill for various reasons, and detecting and treating the diseases early on is essential. Your betta fish can live a long and healthy life with proper care. Here are some of the most common betta fish diseases, their causes, and how to identify symptoms and treat them.

Fin Rot

Fin rot is one of the most common diseases that affect betta fish. It’s caused by bacteria that enter through open cuts, bite marks, or damaged fins. The bacteria then attack the fins, leading to tissue damage and fin loss.

  • Symptoms: ragged or frayed fins, white edges on fins, reddening at the base of the fins, loss of appetite, lethargy, and clamped fins.
  • Treatment: clean the tank water frequently, remove any sharp objects from the tank, add aquarium salt to the water, and use antibiotics prescribed by a veterinarian if the case is severe.

Ich

Ich, also known as white spot disease, is a highly contagious disease that can impact betta fish health. It’s caused by the ichthyophthirius multifiliis parasite that feeds on the fish skin. The parasite looks like white dots on the fish’s body.

  • Symptoms: tiny white dots on the body and fins, rubbing against tank objects, gill movement, and loss of appetite.
  • Treatment: maintain the tank temperature at around 86°f, add aquarium salt to the water, and use medication containing methylene blue or formalin in severe cases.

Dropsy

Dropsy is a severe disease that causes the accumulation of fluids inside the fish’s body. It can also cause organ failure, leading to the fish’s death.

  • Symptoms: bloated stomach, scales sticking out from the body, lethargy, clamped fins, and loss of appetite.
  • Treatment: isolate the infected fish from other fish, change the water frequently, add aquarium salt and BETTAFIX to the water, and use antibiotics prescribed by a veterinarian.

Velvet Disease

Velvet disease is caused by a parasitic infection that affects the fish’s gills and skin. It is highly contagious and can spread to other fish in the tank.

  • Symptoms: a velvet-like coating on the fish’s body, loss of appetite, irritability, and respiratory issues in severe cases.
  • Treatment: raise the tank temperature to 86°f, add aquarium salt to the water, and use medication containing copper sulfate or malachite green as prescribed by a veterinarian.

What are the Causes of Betta Fish Diseases?

There are several causes of diseases in betta fish. Here are some common factors that can contribute to betta fish diseases:

Poor Water Quality
