Does it seem to be raised almost like little warts. Could be Lymphocystis which is like herpes, there is no cure it will go away on it's own. Proper water conditions, varied healthy diet, limited stress and it will run it's course over about a month plus or minus. It seems to develop it's own strain which can be contagious to similar genus of fish. It's really no big deal, my bluejaws got it when I first got them, cleared in qt; then male got it again when introduced into display. Now cleared for many months.
