The Masked Angelfish male is pearly white with anterior portion of the head, from the snout to just behind the eye, yellow orange; anterior half of the caudal fin black; dorsal and anal fins white with a broad orange band distally; the pectoral and pelvic fins orange. Female pearly white with anterior portion of the head, from the snout to just behind the eye black or gray; anterior half of the caudal fin also black; distal portion of pelvic fins orange.
Genicanthus personatus are not schooling fish, but are also less territorial and more passive towards members of the same species. Being planktivores, a diverse diet with frequent feedings is the norm for successfully meeting their dietary needs in captivity. Feed prepared and frozen foods like krill, raw table shrimp, squid, clam and mussel. It is also a good idea to occasionally supplement with some type of herbivore diet containing marine algae and supplement with a sponge fortified formula for Angelfish.
