He's been out for.. i'd say a week or 2 before the Ich Outbreak.
I don't see anything on him.
Especially in his stressed condition of almost being killed, I would assume if there was ich in the QT he'd have it.
He has No tail fin at all. It's just a nub, It's starting to grow back. Open wounds which have since healed. I'm sure Ich would have loved that..
That's still a mystery, I had 3 Chromis who would school, then 3 months later the other 2 are trying to kill him, then the other ones jumped in. I found him near dead floating with no fins left.
I was still a few days shy of my QT cycling again (cuz I wanted to start QTing fish for my 300). So I grabbed a huge net and nabbed him and hung the net inside the tank to shelter the poor guy. When my QT finished I moved him in there...a week or two later ICH in the Main Display.
