Etymology: Chromis: Greek, chromis = a fish, perhaps a perch (Ref. 45335).
More on author: Fowler.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 2 - 12 m (Ref. 4391). Subtropical
Western Indian Ocean: known only from Delagoa Bay, Mozambique to Durban, South Africa. Reported as likely at Seychelles (Ref. 1623) but Randall and van Egmond 1994 (Ref. 10685) believe otherwise.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 12.0 cm TL male/unsexed; (Ref. 4391)
Adults inhabit inshore rocky reefs and weed beds (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).
