I would avoid the dwarf angels. I've had an Eibli for over eight years, and while not feasting on the corals he routinely picks at the open brain corals and the clam mantles to the point that I can't keep any Trachyphyllia. I would remove him in a heartbeat if I could get him out without upending everything else. I've had a starcki damsel for over eight years. Minimally territorial, eats everything, very hardy, and gives tank newbies a hard time for only a day. He's survived three tank transfers in that period of time. Wrasses are good. The flashers and fairy wrasses as a male and two females make a great display. I would not knowingly put a troublesome fish such as a six-line wrasse into a DT early on. It limits your freedom after that. Act in haste repent in leasure.
