Looks more like it's peeling off. I see a tiny piece flapping around w the current
Yup, added him yesterday
Ok thanks. Ya he was fine when added. He definitely looked stressed. Don't have a QT yet but I did just add on a uv sterilizer. Ill pick up an air stone tomorrow for the QT bucket and treat accordingly. Any recommendations on what to use?
Sorry you lost him. It sounds like he wasn't in a QT, if that's the case, you could easily be looking at something very contagious (like brooklynella), so watch other fish closely. The quick death really points to brooklynella, along with the peeling skin.
