Etymology: Chromis: Greek, chromis = a fish, perhaps a perch (Ref. 45335). More on authors: Allen & Randall.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 3 - 50 m (Ref. 7247). Tropical

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 6.0 cm TL male/unsexed; (Ref. 9710)
Adults inhabit caves, ledges, and thickets of black coral on steep slopes (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).
