Etymology: Chromis: Greek, chromis = a fish, perhaps a perch (Ref. 45335). More on author: Valenciennes.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 5 - 45 m (Ref. 7247). Subtropical; 40°N - 5°S, 32°W - 12°E
Eastern Atlantic: including the Azores, Madeira, and the Canary Islands; also reported from west Africa between Senegal and Pointe Noire, Congo.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 12.0 cm SL male/unsexed; (Ref. 7247)
Adults inhabit rocky reefs and sand-weed areas (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).

Bayesian length-weight: a=0.01479 (0.00662 - 0.03303), b=2.99 (2.80 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.45 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (28 of 100) .
