Etymology: Chromis: Greek, chromis = a fish, perhaps a perch (Ref. 45335). More on author: Jordan, Seale.
Environment / Climate / Range
Marine; reef-associated; non-migratory; depth range 3 - 35 m (Ref. 7247). Tropical, preferred ?
Pacific Ocean: Great Barrier Reef and northern New Guinea to Samoa and the Society Islands (Ref. 7247). There are no valid records of this species in the western Pacific north of New Guinea, and none for the islands of Micronesia (Ref. 92902).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm

Adults inhabit passages and outer reef slopes, solitarily or in small groups. They are sometimes seen in mixed aggregations with the closely related species C. margaritifer (Ref. 7247). Feeds on planktons (Ref. 89972). 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).
