Etymology: Pomacentrus: Greek, poma, -atos = cover, operculum + Greek, kentron = sting (Ref. 45335). More on author: Bleeker.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 0 - 10 m (Ref. 7247). Tropical; 35°N - 35°S
Indo-West Pacific: Indonesia (Mentawai Islands), Philippines, Palau, Papua New Guinea, Solomon Islands, Vanuatu, north to the Philippines, Taiwan, and Ryukyu Islands. Reported from New Caledonia (Ref. 26587).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.0 cm SL male/unsexed; (Ref. 7247)
Adults occur singly or in small aggregations at slightly turbid areas of lagoon and coastal reefs. Feed mainly on benthic algae (Ref. 7247). 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). Diurnal species (Ref. 52881).
