I bought a butterfly fish from reef4less.com. The fish arrived healthy and I put it in QT . Fish was eating as well. I didnt treat it with copper for the first 2 days . 3rd day the fish is covered with velvet spots. Its gasping for air under filter. I immediately changed water and added cupramine at .5 . I do fresh water dips for 2 times a day for 3 minutes. Fish stopped eating. Fish is still alive ... I know its hard to tell but will it survive?? what are the odds of survival .. Also cupramine or copper power which one is good for butterflies. I wont buy a fish from reef4less not orth the risk.
