Fin Problem

I just bought a Koi and the tail is long. We left for the day and when we returned the top of the tail is missing. Is this some type of disease? All other fish are fine. - Rob

The Koi could have broken part of his fin off.  Long fins tend to be brittle and can tear if the Koi is mishandled or if the fin catches on something in the pond.  Long fins on older Koi usually take on a ragged appearance, due to normal wear and tear.

The Koi can also have fin rot, a condition caused by a bacterial infection in the fin.  A course of antibiotics prescribed by a veterinarian or a Tricide-Neo dip will treat fin rot.
