Hey everyone! I recently had an outbreak of ich in my tank. Most of my fish died. But most of them looked like this. They started off white but ended up like this. Weird to me. I still have a small hippo tang that somehow has survived and is actually thriving. Doesn’t show any signs of ich or any infection. But that is the only fish in my system. I want to eventually get more but not sure what to do now. Please advise on any suggestions. Thanks in advance!
