Etymology: Chromis: Greek, chromis = a fish, perhaps a perch (Ref. 45335). More on author: Tanaka.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 3 - 72 m (Ref. 86942), usually - m (Ref. ). Tropical; 0°C -

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 10.0 cm SL male/unsexed; (Ref. 7247)
Adults inhabit lagoon and seaward coral and rocky reefs (Ref. 9710), usually in deeper waters (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. 54980; 113699).
