I have been in aquariums for about 8 years and have never had ich.Just recently added a hippo tang to my reef and it has come down with ich.Its driving me nuts because .I did everything rite even acclimated for hours.I have read this and other scale less fish are prone to ich.But why?I have been adding garlic to solve it.I also have some NO-ICH that says it safe for reefs but i am cautios of adding anything to my reef......Any Comments could help...
