Not actually one of the dwarf angels, its a Genicanthus. Oh, and good luck finding a healthy one of those.
In my 60 gallon Reef I have a C. bicolor and C. acanthops (African flameback). Its an interesting color combo. Blue and yellow vs. orange & almost purple. Lot's of color and movement. But Bicolors are notorious for dying on you and being Reef destroyers so not a good choice. Flameback would be good. Its small, hardy, but has LOT'S of Attitude. LOL
Cherubs(Atlantic Pygmy angel) are good, but aggressive.
This choice should be done after reducing that fish load.
Plus Maroons with percs? Your heading for a rumble, with them losing it. Maroons are killers, generally. Most aggressive clowns!
