Beta Fish With a White Fungus

Beta fish were originally bred for their beauty and aggressive nature. Many people keeping these beautiful fish forget that they are as susceptible to disease, as any other freshwater fish. The most common affliction of beta fish is a white fungus that can take several different forms. Their need for a warm freshwater environment provides the perfect conditions for the growth of this affliction.

  1. Prevention

    • Prevention is always better than a having to find a solution when it comes to the health of your beta fish. It is important that the right, stress-free environment is provided. They flourish is slightly acidic water, with a pH range of 6 to 6.5, and require water temperatures between 75 and 82 degrees F. Never mix a beta fish with fin biters or other male betas. This will lead to attacks and excessive stress.

    Beta Fish and "Ich"

    • "Ich" is the common name for a condition that manifests itself as pinhead-sized white dots on the skin and fins. A badly affected beta fish will gasp for air at the surface because of gill obstruction. As the severity of the "ich" increases, the white dots will gather into a cottony mass.

    Other Fungus

    • Another fungus, known as Saprolegnia or Achlya, could be responsible for the white cottony growth on a beta fish. This fungus will break down the skin and destroy the gills. The warmer the water, the more rapidly these parasites will grow and develop. Over time, the body of the beta will begin to lose its color and become covered by the white fungus.

    Treatments

    • "Ich" may be treated with a simple anti-fungal treatment available at any pet store. The application is dependent on the concentration of medicine. Apply using the instructions included. For Saprolegnia or Achyla, treat with a acriflavine concentrate. This will also be available at any pet store. The acriflavine can be applied up to 5 ml per liter. As the fish is recovering, 20 percent of the water should be siphoned out every two to three weeks and replaced with conditioned water of the same temperature, gradually reducing the strength of the treatment.

    Precautions

    • When treating your fish, never combine multiple treatments. The results will be unpredictable and could prove fatal to your beta. In addition, never use medication as a preventative measure. Fungus medication is oisonous to a healthy beta fish. Finally, always provide adequate aeration during the beta fish's recovery. Proper oxygen levels will encourage a return to full health.
