Noted yesterday that my anthias was not out swimming around. When he did come out he wasn't eating. Closer inspections I found scales lifted and a few light tan specks on his head. Today more scales are raised and he was staying in the upper corner of the tank...also not eating. Went to look just now and he is hiding. Anyone know what to do. I can't give water params because I just did a water change. Everything else is fine. Bubba
