I would guess the tang also, but it is just a guess at this point, of course.
I recently put my hippo tang back into my main tank, after a stay in the hospital tank, and my Kole tang immediately started to beat the living daylights out out of him!

I placed a sheet of eggcrate in the tank to separate them, and after 3 days separated, they are now getting along fine. That's in a 204 gallon. Tangs can be very aggressive, and I've even seen a purple tang repeatedly stab an already dead fish. :shock:
The more I learn about fish, the more I'm convinced that the bigger a tank is, the better. Instead of buying a $300 fish, I would rather put that money into a bigger tank. The results of stress caused by a smaller tank is too unpredictable.
Now I want a bigger tank!
