Etymology: Chromis: Greek, chromis = a fish, perhaps a perch (Ref. 45335). More on authors: Fowler & Bean.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 2 - 35 m (Ref. 48636). Tropical; 8°N - 12°S
Indo-Pacific: Christmas Island, Indonesia, Philippines, Palau, New Guinea, New Britain, Solomon Islands, and northern Great Barrier Reef of Australia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.0 cm TL male/unsexed; (Ref. 48636)
Adults are found singly or in loose aggregations above the upper edges of outer reef slopes with rich coral growth. Often at the entrance of large caves or near its ceiling (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). Maximum depth reported taken from Ref. 48636. Diurnal species (Ref. 52881).

Estimates based on models
Preferred temperature (Ref. 115969
): 27.6 - 29.3, mean 28.8 °C (based on 823 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01738 (0.00792 - 0.03811), b=3.01 (2.84 - 3.18), in cm total length, based on LWR estimates for this Genus-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
