In my 240g reef I am wanting to add some different fish. I have a blue tang, 3 chromis, yellow tang, and diamond goby. I am trying to figure out what else I can add that is not your typical fish you see all the time. What would you add in the reef tank? The marine beta is cool but 50/50 on getting along in a reef tank so I decided not to. The coral beauty and emporer I don't want because everyone I know already has them lol.

Throw ideas at me... I like schooling and/or color! Oh, none that may eat my corals again.
