Having my tank for 4 years now I’ve always battled ich I do not have a qt so I always thought if you kept them well fed they’ll be ok...my wrasse is itching against the sand I know it’s ich because my goby has it also... question is is she a goner or can I keep this beauty alive?! Taking the fish out for however long they say is not a option...I have a uv light that I plan on getting a new bulb for today as it has not been running in months any actual reef safe ich treatments out there or is it all bs?? Ty you professionals !
