Etymology: Chromis: Greek, chromis = a fish, perhaps a perch (Ref. 45335). More on authors: Randall & McCarthy.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 5 - 20 m (Ref. 7247). Tropical
Western Indian Ocean: Persian Gulf and Gulf of Oman.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 11.5 cm TL male/unsexed; (Ref. 11441)
Adults inhabit inshore coral or rocky reefs (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).

Estimates based on models
Preferred temperature (Ref. 115969
): 25.6 - 29.2, mean 27.4 °C (based on 431 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
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
): 3.0 ±0.1 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (23 of 100) .
