Fungus

Symptoms Cotton-wool like growths on the body of the fish, usually greyish-white, but can be darker. Some bacterial diseases may be mistaken for fungus, including the so-called mouth fungus, which is actually caused by bacteria.

Causes Fungal spores are always present in the aquarium, and an outbreak of fungal disease usually occurs after damage to the fishes skin or gill area, and as a secondary infection.

Possible cures Commercial anti-fungal remedies can be used to destroy the fungus and prevent it spreading. These include Interpet #8 Anti Fungus and Finrot and Waterlife Protozin. Most medications avaialble for treating fungal infections will also treat bacterial infections, providing a safety net in the case of mis-diagnosis.
