Lymphocystis
Symptoms: Nodular white swellings (cauliflower) on fins or body.

Lymphocystis is a virus and, being a virus, affects the cells of the fish. It usually manifests itself as abnormally large white lumps (cauliflower) on the fins or other parts of the body. It can be infectious, but is usually not fatal. Unfortunately, there is no cure. Fortunately, this is a rare disease.

There are two suggested treatments. One treatment is to remove and destroy the infected fish as soon as possible. The other treatment is to simply separate the infected fish for several months and hope for remission, which usually does occur.
