I just bought a 7" powder blue tang from my LFS at a really cheap price and I couldn't pass it up. He was being treated with copper for the past 2 months and was clean from ich so I figured not to QT him. I've heard they are challenging to keep but I like a good challenge. I'd like some stories on keeping these though just to get an idea of what I'm in for. Also he's super fat and loves nori.
