I noticed tonight some white spots on my yellow tang. It was quarantined a month prior to tank addition so it must have already been in the tank. What can I do? Are fresh water baths helpful or should I quarantine and treat it? Should I treat all the fish (don't really have a quarantine large enough) or is treating it enough? I know this has been talked about before but would appreciate any advise you can give to a newbie. Can they fight it off themselves?
