Dorsal spines (total): 15 - 16; Dorsal soft rays (total): 15 - 16; Anal spines: 3; Anal soft rays: 14 - 17. Males light blue with 8 black stripes on the lower 2/3 of the body (the posterior end of the uppermost yellow, the lowermost stripes extending the adjacent anal fin); females light blue with a vertical black bar above the eye and spots on the forehead; both sexes with a broad submarginal band on the dorsal and anal fins; females with broad submarginal band on the caudal-fin lobes.

Biology     Glossary (e.g. epibenthic)

Occurs in current-swept outer reef slopes and drop-offs (Ref. 4859). Feeds on plankton. Forms harems of 2-5 individuals. Occasionally exported through the aquarium trade (Ref. 48391).

Estimates based on models

Preferred temperature (Ref. 123201): 24.2 - 28.7, mean 26.5 °C (based on 65 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.03090 (0.01359 - 0.07026), b=2.89 (2.70 - 3.08), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.45 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Price category (Ref. 80766):   High.
