Unfortunately bacterial infections
are very common in Tropical Fish. They can be a very deadly
disease especially if left untreated. Bacterial infections
cause diseases which can infect the body of the fish and spread
rapidly to the point where the fins and other extremities
can begin to deteriorate.
Poor water quality is a leading cause of bacterial infections
in fish. If you suspect that your fish may have a bacterial
infection the first step would be to take a water sample to
your local pet shop or veternarian to have it tested.
If your fish appears to have red inflamed areas on the outer
body it may very well have a bacterial infection.
Beware that bacterial infections can spread rapidly to all
other fish that are housed in the same aquarium. The first
thing that you should do after you confirmed a bacteria infection
is move all the fish out of the original tank and quarantine
the infected ones. From there it is suggested that you disinfect
entirely the original tank and all items inside of it before
moving the fish back. Do not move the infected fish back into
the general population until you are sure you have eliminated
