he is doing fantastic, he was large enough so that the other tangs left him alone and small enough to fit into all of the cool little places that tangs love to go. if you are thinking about getting 1, i would say go for it, but remember that these guys can be quite aggressive, mine isn't but that may be because all of the other fish in the tank have been able to take care of themselves, but in my eyes, i say these guys are worth the risk.
