So I was feed in my clownfish and other fish tonight and saw that the female clown have a puffy white spot on it, and whenever white lighting is on, it looks black. All the fish are currently in a quarantine tank because my tank has ich in it. So, I am treating the quarantine tank with copper. Current livestock in the quarantine tank is a tomini tang, who I suspect is the culprit, a Midas blenny and another clown. If it is an infected wound, would the treatment for it be safe to use with copper power. Here are some pics:
