Tang in a 75?

[snaggle]

I know the tang police might get me but what kind of tangs other then a yellow tang can I keep in my 75g tank. The dimensions are 48"x16"x24" it has a 20g sump but I am making a new system. It will have a 20g fuge a 29g sump and a 10g sump/fuge for cheto to grow in. As for fish I have two juvenile clowns a tomato and an ocellaris, 3 green chromis, a yellow dwarf angle and an engineer goby. The angle will be moving I think. As for corals I have GSP, PSP, Zoos, an open brain and a large hairy mushroom. There are also some mushrooms that pop up every now and then. I don’t know what kind of tang I can add if any so please help me. I am not looking to get flamed, I just think they are nice fish and my girl friend wants one too, that is why I am asking before hand.
