Observations: A whitish haze or "velvety" appearance. 

Conditions: Dirty water in conjunction with high ammonia and/or nitrate levels. This is indicative of a filtration problem. 

Fish Affected: Live-bearers, danios, and tetras. 

Cure: Malachite and Formaldehyde; Acriflavine is also effective. Raising the normal one teaspoon of salt to two teaspoons is also helpful. 

General medication tips: 

When starting a treatment program, keep the following tips in mind:

 • Different products may contain varying amounts of the active ingredient. Follow instructions on the package carefully. 

• Make sure the treatment program is continued for the entire prescribed length of time. 

• Do not add new fish to the treated tank or transfer any fish being medicated to a community tank. 

• Keep one teaspoon (minimum) of salt per gallon in the water. 

• Monitor ammonia and nitrite levels, keeping them at zero. 

   A review of the causal factors in all these diseases- overcrowding, poor filtration, high ammonia levels, and rapid temperature and/or pH changes- reveals a common link: All relate to water quality.
