Fin Rot

Overview:

Common Names: Fin Rot, Tail Rot
Disease Type: Bacterial (gram negative organism)
Organism: Aeromonas, Pseudomonas fluorescens, or Vibrio

Description:

Fin Rot is one of the most common, as well as most preventable, diseases in aquarium fish. Although it is caused by several types of bacteria, and often occurs concurrently with other diseases, the root cause is always environmental in nature. Fin Rot can be difficult to cure, particularly in the more advanced stages. If left untreated, it will eventually kill the diseased fish and infect all the other fish in the tank.
