The protozoan Tetrahymena is not a real parasite, it appears only if the mucous membrane is infected by fungus or bacteria. It feeds on bacteria and isolated cells of the destroyed tissue. In overcrowded aquariums, Tetrahymena multiply rapidly due to dirty water. Large amounts of these protozoa infect the mucous membrane of fish.
How to cure:
The anti-parasite remedies effectively deal with Tetrahymena if treatment is consistent is carried out according to the manufactures’ instruction. In exceptional cases, at pH of 8, or when strong biological filters are used it is necessary to add the usual dose of the remedy daily for three days. Before medication is administered, a 30% water change should be carried out. The application of the anti-fungal and anti-bacterial remedies in the early stages will help to prevent a secondary bacterial or fungal infection.
