The Regal Angelfish is more difficult to maintain than other species of angels so it should be introduced first so that it may stake out its territory in advance of other fish. A minimum of a 125 gallon tank with plenty of hiding places and live rock for grazing will offer a good environment. The Regal Angelfish may nip at large-polyped stony corals, an occasional soft coral and clam mantles, but may be kept with small-polyped stony corals and somewhat noxious soft corals.
