Etymology: Pomacanthus: Greek, poma, -atos = cover, operculum + Greek, akantha = thorn (Ref. 45335). More on author: Cuvier.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 3 - 40 m (Ref. 9710). Tropical; 32°N - 25°S, 92°E - 162°E
Indo-Pacific: Indonesia to Papua New Guinea, north to the Philippines, south to Rowley Shoals and the southern Great Barrier Reef; including Palau and Yap in Micronesia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 28.0 cm TL male/unsexed; (Ref. 9710); max. reported age: 15 years (Ref. 72479)
Occurs in coral rich areas of clear lagoons, channels, and protected outer reef slopes. Changes to adult pattern is dramatic, and intermediate stage are rarely seen (Ref. 48636). Often solitary. Feeds on sponges and tunicates. Uncommon (Ref. 9710). Highly prized aquarium export (Ref. 37816).
