Etymology: Chromis: Greek, chromis = a fish, perhaps a perch (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Écologie
marin récifal; non migrateur; profondeur 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)
Taille / Poids / Âge
Maturity: Lm ?  range ? - ? cm
Max length : 16.0 cm TL mâle / non sexé; (Ref. 9710)
Épines dorsales (Total): 13 - 14; Rayons mous dorsaux (Total): 11-13; Épines anales 2; Rayons mous anaux: 10 - 11.
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).
