Looking to add just one 'nice' fish to my tank once it is established. I'm short on space so it's going to be a few small fish, a tang and I would like to have an angel or a butterfly. I've heard mixed reports on them being reef compatable. I want to eventually add some soft corals so I am trying to plan ahead. The fish I would like to have are passers angel,flame angel, emperor angel, copper band butterfly or a racoon butterfly. Any advice on either of them being reef safe or other suggestions?
