Larry, are these raised, and do they actually come off? It might almost be worth it to hold the fish in the net, even do this while the fish is underwater, and remove one of these things if they come off relatively easily, and then look at it under a microscope or even with a magnifying glass.
I just want to be sure these are not "spots" or otherwise normal coloration of the fish, like you see in OB peacocks, or in some hybrids.
