Last week, I noticed my pacific blue tang had what looked like a bleached out spot on his top fin and it kind of carried down onto his body a bit. This was about the best pic I could get. I went to the lfs
and they gave me some tetracycline that he seems to be eatin up. It looks a little better, but this pic didn't really show how "bad" it was anyways. Is it some sort of fungus? Am I treating it correctly?
Also, and this may be completely unrelated, my smaller percula clownfish has what looks like an open wound to me, but my girlfriend seems to think otherwise. Does this look familiar to anyone? In addition to feeding the tetracycline to everyone (which the clowns dont seem to like much) I added some additional NovAqua+ to the tank.
