Etymology: Pomacentrus: Greek, poma, -atos = cover, operculum + Greek, kentron = sting (Ref. 45335). More on author: Jordan, Seale.
Environment / Climate / Range
Marine; reef-associated; non-migratory; depth range 1 - 45 m (Ref. 7247). Tropical; 33°N - 23°S
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 10.0 cm FL male/unsexed; (Ref. 5525)
soft rays: 15 - 16. The background color of this species varies from light tan to deep blue or dark brownish purple. The juvenile is similar to that of P. bankanensis, but lacks a bluish stripe on the exact mid-dorsal line of the snout forehead.
Pacific Ocean: Moluccas to Samoa, north to the Izu Islands, south to Rowley Shoals in the eastern Indian Ocean and New Caledonia.
Comprises several color forms, or geographical variations (Ref. 48636). Adults are found in mixed coral and rubble areas of lagoon and seaward reefs from the lower surge zone to a depth of 40 m (Ref. 1602). Solitary (Ref. 37816). Feed on filamentous algae and small invertebrates (Ref. 1602). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
