Betta Fungus Disease

Fungus on a betta fish appears as white, fluffy, cotton-like growth on the body or the fins. Sometimes the fungus appears to be long strands of white hair. Betta fungus disease is common. Prompt action is key if you think your betta has a fungus.

  1. Causes

    • According to Aquarium Life, fungal infections in betta fish often follow some other health problem like parasitic attack, injury or bacterial infection.

    Dangers

    • Fungal infection is contagious and can kill, so it is important that you treat and control the fungus as soon as possible.

    Prevention

    • Maintaining a clean tank and good filtration help to protect your betta from fungal infection. Ultraviolet sterilization also prevents fungal diseases.

    Precautions

    • Betta fish are more susceptible to fungus when the mucus coat on the skin is worn down because of poor water conditions or injuries.

    Treatment

    • After the cause of the fungus has been discovered, Aquarium Life recommends adding a solution of phenoxethol at 1 percent distilled water to your aquarium; 10 ml per liter of water is recommended. Do not repeat this process more than one time as the treatment can be dangerous to other life in your aquarium.
