Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 26.0 cm TL male/unsexed; (Ref. 9710)
Dorsal spines (total): 13 - 14; Dorsal soft rays (total): 23 - 26; Anal spines: 3; Anal soft rays: 19 - 22. The abdominal region of females is noticeably thick set. Body is golden yellow; base of the posterior portions of the dorsal and anal fins black; a prominent vertical black bar running across the eye; diagonal rows of black dots on the sides. A filament originating from the soft portions of the dorsal fin rays trails posteriorly (Ref. 4855). Snout length 2.4-2.9 in HL. Body depth 1.6-1.9 in SL (Ref. 90102).
Uncommon species (Ref. 9710) found in coral rich areas of clear water lagoon and semi-protected seaward reefs. Usually in pairs or small groups, more wary than most species. Minimum depth reported taken from Ref. 30874. Oviparous (Ref. 205). Minimum depth reported taken from Ref. 128797.

Estimates based on models
Preferred temperature (Ref.
123201): 24.9 - 28.9, mean 27.7 °C (based on 646 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02291 (0.01133 - 0.04632), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.7 ±0.25 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (16 of 100).
