I have a purple tang that has been doing fine for several months. However,
recently he has developed something around his eye, and it appears to also
be on a line on his side as well. It isn't white, maybe brown spots.
Anyway, I tried treating with Melafix and Pimafix, but that didn't work. I
did several water changes as well. Does anyone know what this might be and
how I can treat it? It doesn't appear to be ick or coral reef disease, but
I could be wrong. It isn't getting worse that I can tell and he is still
eating. All water parameters are normal. Any help you can give me would be
greatly appreciated. Thank you.
