I have one in my fowlr...it is in with a chocolate tang, star triggerfish, humu humu, and a dog face puffer, and a chain link eel...He was the last fish I added and everyone seemed to pick on him at first...apparently they have all figured out that he is very venomous..because noone messes with him now..he even takes food away from the large humu humu..and by the way his best bud in the tank is now the tang, so I would say go for it...You may want to be prepared to move some of the rocks around though, it is amazing how well that little trick works!!
