Maturity: Lm ? range ? - ? cm
Max length : 3.0 cm SL male/unsexed; (Ref. 48637)
Dorsal spines (total): 6 - 7; Dorsal soft rays (total): 8; Anal spines: 1; Anal soft rays: 8. Distinguished by the following characters: a bony interorbital about 2/3 pupil diameter in width and only slightly concave; absence of troughs or trenches in the interorbital or posterodorsal orbital regions; unbranched fifth pelvic-fin ray, 50-60% fourth ray; epaxialis extending anteriorly to a vertical in line with the posterior margin of the orbit (Ref. 100726); no elongated spines; all pectoral rays unbranched; longitudinal scale series 23; absence of predorsal scales on midline; 1-2 deciduous scales on upper opercle; depth of body 4.0-4.1 in SL; semi-translucent pink on upper half of body (straw-yellow, translucent above midlateral septum, Ref. 100726); midlateral stripe is broad and reddish orange in color; breast and belly, white; narrow light blue lines below eye, dorsal midline of snout and behind upper rear corner of eye (Ref. 90102).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Inhabits coastal reef slopes and lagoons. Found along reef margins with rubble (Ref. 48637). Also found in caves and crevices, often on drop-offs in 3-35 m (Ref. 90102). A relatively rare species in collections, usually been taken in lots of one or two specimens (Ref. 100726)..

Estimates based on models
Preferred temperature (Ref.
123201): 26.3 - 28.9, mean 27.8 °C (based on 302 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
