Indo-Pacific: Red Sea and East Africa (south to the latitude of the Xora River, South Africa) to the Marshall Islands and French Polynesia, north to Japan, south to Australia.
One of the most common of the squirrelfishes that occurs in outer reef areas, also encountered in lagoons and drop-offs from less than 2 to 40 m; either solitary or in groups (Ref. 27370). Nocturnal, feeds mainly on benthic crabs and shrimps.

Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (-0.16711 - 0.17489), b=3.12000 (3.03000 - 3.21000), based on all LWR estimates for this BS (Ref.
93245).
Trophic Level (Ref.
69278): 3.9 ±0.67 se; Based on food items.
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref.
59153): Low vulnerability (20 of 100) .
