You will have to keep an eye on the coral beauty as most dwarf angels pic at corals.
As far as the large Angels, forget about keeping any meaty corals like brains, clams, etc I have an Emporer adult that i got when he was a juv and has eaten 2 carpet anemones, brain, zoas, etc...
Its tough deciding which fish to get, i am trying to decide myself for my last fish...thinking Powder Blue Tang , Accilles Tang, or female Bellus Angel
