Finrot

Symptoms The fins become opaque and ragged, and may be blood-streaked. The fin erosion may continue until it reaches the base of the fin, at which point fish usually die. It is therefore important to catch this disease early.

Causes The disease is caused by various bacterial species, which are normally present in aquarium water, but do not infect healthy fish. The disease is usually triggered by poor water quality or where fin damage has occured, often caused by fin-nipping fish.

Possible cures Commercial anti-bacterial remedies are available to destroy the bacteria and halt the damage. The commercial products available include Waterlife Myxazin, Interpet #8 Anti Fungus and Finrot and Maracyn by Mardel Labs.
