Have you ever added anything yellow after him??
Mellow test... put a yellow post-it note on the side of the tank and see if he tries to flick it with his tail...
WVgolfer, I added a copperband butterfly and mine did the same thing. I had to QT him for a few days. Rearranging the rock might help, if you can do that. Or adding something to the tank that the tang isn't used to, like a big piece of LR or even a large fish net. Just let it sit there and the tang should be intimidated by it, but the new fish will not since he's not "used to" the environment yet.
