Its hard to tell from the pic but it looks like your fish has red bumps. Mine had what I can best describe as a whitehead pimple, and it was only one. It didn't seem like ich from what I have read, but I figured I would try the temp/salt treatment because it wouldn't harm the fish either way. Once in the hospital tank it also developed minor peeling of skin on its lips. Both cleared up in 5-6 days. Not sure what that was but I tend to think the temp/salt helped take care of it.
