Etymology: Chromis: Greek, chromis = a fish, perhaps a perch (Ref. 45335). More on author: Randall.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 12 - 95 m (Ref. 1602), usually - m (Ref. ). Tropical; 0°C - ; 16°N - 23°S
Indo-Pacific: Christmas Island in the eastern Indian Ocean to the Society Islands, north to Mariana Islands, south to New Caledonia; throughout Micronesia. Replaced by Chromis nigroanalis in the west Indian Ocean (Ref. 37816).

Maturity: Lm ?  range ? - ? cm
Max length : 8.5 cm SL male/unsexed; (Ref. 7247)
Adults occur in clear lagoon and seaward reefs, usually seen singly or in loose aggregations near caves and ledges. Abundant over branching corals and leeward coasts (Ref. 9710). Feeds on planktons (Ref. 89972). Diurnal species (Ref. 113699). 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).

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=3.00 (2.83 - 3.17), 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
): Low vulnerability (22 of 100) .
