That rabbit was going to be my suggestion, darn you Bang!
As for the dwarf angels and being reef safe, Coral Beauties are almost never an issue, especially if they're well fed. Flames are usually okay, but IMO not as safe.
A nice school of anthias would be nice.
Also, although not always the prettiest, a little algae blenny like a bi color would be cool. Their personality makes up for the lack of looks.
What about a bottom dweller like a Greenbanded Goby?
Possibly a reef safe butterfly? I LOVED my Copperband Butterfly and it never touched a coral.
