Etymology: Chromis: Greek, chromis = a fish, perhaps a perch (Ref. 45335). More on author: Smith.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 3 - 65 m (Ref. 1602). Tropical; 31°N - 30°S
Indo-Pacific: East Africa to the Hawaiian and Pitcairn islands, north to the Ogasawara Islands, south to the Great Barrier Reef and New Caledonia. Primarily around oceanic islands.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.5 cm SL male/unsexed; (Ref. 7247)
soft rays: 12 - 14. Fish is rich golden brown, shading to purplish pink on lower head and chest. This species is distinguished from other similar Chromis by the large dark spot at the pectoral fin base.
Adults occur in clear lagoon and seaward reefs, usually in loose aggregations near caves and ledges. Abundant over branching corals and leeward coasts (Ref. 9710). Benthopelagic (Ref. 58302). Feeds on planktons (Ref. 89972). 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).
