Etymology: Pomacentrus: Greek, poma, -atos = cover, operculum + Greek, kentron = sting (Ref. 45335). More on author: Bloch.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 1 - 18 m (Ref. 89972). Tropical; 16°N - 32°S

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 8.5 cm SL male/unsexed; (Ref. 7247)
Adults inhabit sandy areas of lagoon reefs, around isolated patch reefs, coral heads, or rubble. Usually in groups (Ref. 4391, 48636). Commonly found around jetty structures (Ref. 48636). Feed on zooplankton and filamentous algae (Ref. 7247). Diurnal species (Ref. 54980; 113699).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
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).
