Etymology: Chromis: Greek, chromis = a fish, perhaps a perch (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 12 - 40 m. Temperate

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 15.0 cm SL male/unsexed; (Ref. 7247)
Adults inhabit steep slopes and rocky bottoms mainly on offshore reefs (Ref. 7247). Diurnal species (Ref. 52881). 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).
