Aggressiveness: Semi-aggressive. Cannot be kept with other Angelfish. It will chase small fish such as blennies, clownfish, and gobies.
Reef Compatibility: With caution. May eat some soft corals and nip at large Polyped stony corals, zoanthids and clams. Juvenile specimens are less dangerous for the reef. Adults are better kept in fish only systems.
Distribution: Indo-Pacific: Maldives to Vanuatu, north to the Yaeyama Islands; Palau and Krosae in Micronesia

The Blueface Angelfish is from the Indo-Pacific region where it is found in coral rich areas of lagoons, channels, and outer reef slopes at depth of 20 to 90 feet. Juvenile specimens are mostly found in shallow waters and in inshore caves. It is found from 25°N to 24°S.
Adult and juvenile of this species differ markedly in coloration.
Juveniles are covered with alternating vertical black, white and sapphire blue stripes. When it reaches a length of approximately five inches, the juvenile begins to morph into its adult coloration. Scales of the adults are blue with yellow margins. The breast, pectoral and caudal fins are yellow and have a black spot at the posterior base of the dorsal. The face is blue, with small yellow spots that extend from eye to eye, but not much beyond each eye.
The ideal aquarium should provide plenty of swimming and hiding places as well as large amounts of live rock for grazing. Water temperature should be at 72-78°F, specific gravity at 1.020-1.025 and pH between 8.1 and 8.4. It is best to have a refuge for this fish.
