Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri

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).

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). 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=0.01830 (-0.16290 - 0.19951), b=2.99012 (2.90199 - 3.07825), based on LWR estimates for this genus-BS (Ref. 93245).

Trophic Level (Ref. 69278): 3.0 ±0.1 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low vulnerability (22 of 100) .

Price category (Ref. 80766): Unknown.
