Hi, I just reintroduced my clownfish to my display tank after a 3 month QT period. After a day he developed a sort of white fuzzy patch on his white band. Today I noticed a single white dot on his face. Since the DT was fallow for 3 months, and he was in QT for 3 months I am wondering if this is just stress or disease related? If so what should my next steps be? He is behaving pretty normally.
