anything with a larger body might have problems with the tang. That includes angels. But like Kurt said, depends on your tang's temperment - which I know may be hard to judge with the damsels.
In the past, I added a foxface rabbitfish - yellow, with a similar shaped body to the tang. It was serious bully time for about the first week or so. Then the tang settled down and could be seen eating side by side. The only problem was either when they wanted the same hiding spot or if the tang just felt like flexing his muscles to remind the foxface that he was in charge.
Sounds like you may end up trying new fish and being prepared to move rock and catch fish in case of problems.
I can almost hear the dice rolling in your head about now.
