Thanks for the advise and the welcome.
I have two wrasses that are about twice the size of the grouper in the tank with the grouper. They seem to be getting along fine. In fact they share many of the same hidding places. I'm also thinking about getting a triger or filefish and maybe a puffer. I would think with their built in defences they would do fine with the grouper. My wife really wants some blue damsels though.
