green is algae is secondary to bacterial infection which is secondary to thick slime
coat due to parasites or bad water. best is remove the fish to separate hospital
facility like a 100 gallon rubbermaid water tank.

better to not treat the whole pond BUT
if any other fish have anything on em, then do treat. this one could be spawning
injuries. Ingrid

I just discovered that one of my larger fish has what appears to be a fungus
growing on both sides of him. It is greenish in color and covers almost 50%
of his sides.. The fish is not feeding and spending most of the time near
the surface, but at a correct attitude. Does any one have any idea what the
problem could be? Should I remove him from the other fish to prevent
spreading of what ever it is? And can I treat the entire pond with anti
parasite/antifungul agents (3500 gallons, about 75 fish) without fear of
harming the other fish? Thanks in advance, Bob
