Indo-Pacific: most islands of Oceania except Hawaiian Islands, Marquesas, and Pitcairn Group; also Australia north to the Ryukyu Islands. In the Indian Ocean, there are confirmed records Seychelles, Thailand and Western Australia. Often confused with Chromis viridis.
Adults inhabit clear lagoons, passages, and seaward reef slopes, in thickets of live or dead coral. They occur in large aggregations feeding above staghorn Acropora corals (Ref. 9710). Stomach contents of individuals examined included mainly copepods, amphipods, and zoea. 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 of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02137 (-0.09842 - 0.14116), b=3.07 (3.00 - 3.14), based on LWR estimates for species & genus-BS (Ref. 93245).
Trophic Level (Ref. 69278): 3.1 ±0.2 se; Based on diet studies.
Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153): Low vulnerability (23 of 100) .
