Etymology: Chromis: Greek, chromis = a fish, perhaps a perch (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
; marino associati a barriera corallina; non migratori; distribuzione batimetrica 6 - 40 m (Ref. 7247). Subtropical; 35°N - 34°S
Western Pacific: there are two isolated populations: (1) southern Japan, Ryukyu Islands, and Taiwan; (2) Coral Sea, New Caledonia, Loyalty Islands, Lord Howe Island and east coast of Australia between Sydney and the southern Great Barrier Reef. Reported from New Zealand (Ref. 35942) and Tonga (Ref. 53797)
Size / Peso / Age
Maturity: Lm ?  range ? - ? cm
Max length : 16.0 cm TL maschio/sesso non determinato; (Ref. 9710)

Adults inhabit lagoon and outer coral reefs, boulder bottoms and lava cliffs, in small to large aggregations (Ref. 7247). Diurnal species (Ref. 113699). 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).
