It was with great trepidation that we have resolved to make this part of the web-site accessible to guests. The first consideration was that there are so many “knowledgeable” persons that make it their business to criticise, that I dread getting into hours of debate regarding the treatment of fish.

Treating Koi with chemicals are harsh and these chemicals are poisonous to such an extent that it kills lower life forms like parasites, fungus and bacteria without killing the fish. It stands to reason therefore that most treatments are to a certain extent harmful to the Koi, and in some cases deadly for other species of fish. The treatments describe in this section were developed either through trial and error over many years, or it has been confirmed with Koi Health Experts all over the world. The bottom line is that not a single treatment is described in this section that I have not utilised myself for considerable time.

The biggest concern is that readers who have very little experience in Koi keeping may not understand the full spectrum of factors that may influence the treatment. Failure to understand all factors will result in a dead fish or failure to cure the disease. I am not present when you treat your fish and can therefore not be held responsible for losses or damage. If you are not confident in your abilities, please contact a knowledgeable person in your area to assist you.

Treating infected/split fins


Tail or fin rot

Tail or fin rot is primarily caused by Aeromonas bacteria that gained entry to these powerful yet delicate bone and tissue structure. When caught early, the treatment is simple as described under treatment of ulcers. There are however times when the fins may be red with frayed areas or times when the problem is noticed when there are areas where the fins have been eaten away to a large extent. One of the tell-tale symptoms is where the fins have been destroyed in wide semi-circles from the edge, resembling large “bite marks”. One thing that is curious about fin-rot is that the bone rays as well as the much more fragile tissue between the fin rays are destroyed at the same rate.
