Morphology | Morphometrics
soft rays: 7 - 9. Dark bands lacking a pale central area; width of pale bands clearly less than width of dark bands; pattern on cheek usually consisting of 2-4 wide bars radiating from ventral portion of eye, occasionally with portions of bars broken into spots, and the dark bars covering most of cheek, no large unpigmented area anterior to preopercular margin; pectoral-fin base with a single spot, usually covering most of base, the ventral portion of the spot often more intensely pigmented; pectoral-fin rays modally 17 (Ref. 34188).
Most collections taken from the bases of patch reefs or coral encrusted boulders with undercut ledges (Ref. 34188).

Estimates based on models
Preferred temperature (Ref. 115969
): 24.3 - 28.3, mean 27.1 °C (based on 419 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00475 - 0.02204), b=3.03 (2.85 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.4 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 (10 of 100) .
