A small barb in one of my tanks seems to have some kind of rash (a bit like white spot) on its tail fin. It appears to be the same colour as the tail (orange) only a bit darker. I can't see any more of it on any other part of the fish or on any other of the fish in the tank. The fish seems to be behaving and feeding normally, though maybe flicking a bit. Does any one have any idea what this might be and how best to deal with it!?
