You might want to rethink the blue headed wrasse also. I don't think they directly eat corals, but will dig and upset rockwork as well as eating shrimp and crabs.
You already have a tang, but in my 75 I have a Kole tang, ocellaris clown, bangaii cardinal, ochre-striped cardinal, a blue sided fairy wrasse, and a royal gramma. (I think on the gramma - I added him to the tank Saturday and haven't seen him since. I hope he's just hiding somewhere.) I'd like to add a black occellaris and a watchman goby of some sort. I reacd about another memer having like 5 flasher wrasses and 3 fairy wrasses in his 150. I may try to add a Carpenter's wrasse at some point. I'm also considering a trio of chromis or pajama cardinals.
