Etymology: Chromis: Greek, chromis = a fish, perhaps a perch (Ref. 45335).
Environment / Climate / Range
Marine; reef-associated; non-migratory; depth range 4 - 40 m (Ref. 7247). Tropical, preferred ?
Indian Ocean: widespread in the western Indian Ocean and Andaman Sea; also known from Christmas Island. Western Pacific: Taiwan, Australia and Vanuatu Island.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 17.0 cm TL male/unsexed; (Ref. 90102)
Adults inhabit outer reef slopes and deep lagoons (Ref. 9710). They form small to moderate aggregations on reef crests with moderate currents (Ref. 48636). 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).
