isolate the main culprit, not the secondary invader columnaris.

these pictures fish is well beyond treatment, but you would be surprised how
many fish get to this stage before the problem is noticed. These pictures were
sent to me by a client who checks his fish every day, but it's a very large
I have found fish as advanced as the ones in the
pictures in small koi ponds of 1000gal and who have diligent owner. The best
way to check is when the fish are feeding - if they cannot take pellets off the
surface - if food comes out the gills or if they will not feed when other fish
are about. And there's many more.

damage. There's a bacterium, or it may be it's a cocktail of bacteria, which
