(Perch-likes) > Pomacanthidae
Etymology: Pomacanthus: Greek, poma, -atos = cover, operculum + Greek, akantha = thorn (Ref. 45335).
Environment / Climate / Range
Marine; reef-associated; non-migratory; depth range 5 - 30 m (Ref. 90102). Tropical; 25°N - 24°S, 72°E - 170°E
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 38.0 cm TL male/unsexed; (Ref. 9710)
Indo-Pacific: Maldives to Vanuatu, north to the Yaeyama Islands; Palau and Krosae in Micronesia (Ref. 1602).
Found in coral rich areas of lagoons, channels, and outer reef slopes. Often near caves (Ref. 9710). Juveniles settle in very shallow inshore caves with algae growth (Ref. 48636). Usually solitary. Feeds on sponges and other encrusting organisms (Ref. 6113) and tunicates. Occasionally exported through the aquarium trade (Ref. 48391). Individuals under 20 cm in length are best adapted to tank life (Ref. 4907).

Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.03090 (0.01329 - 0.07187), b=2.90 (2.72 - 3.08), based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 2.7 ±0.00 se; Based on food items.
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
