Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 3.5 cm SL male/unsexed; (Ref. 559)
soft rays: 8 - 9. Diagnosis: frontal ridge behind the orbits slopes steeply into a wide interorbital trench
anteromedially, and into postorbital trenches laterally; posterior nasal opening separate from anterior margin of eye; elongate first dorsal spines absent; fifth pelvic fin ray branched once
dichotomously; body red-orange with four white dorsolateral spots between caudal region and origin of second dorsal; no white ventrolateral spots; facial pattern with two thin, diffuse white diagonal lines under orbit and one over preopercle (Ref. 57688).
Inhabits clear lagoon and seaward reefs; within crevices and caves of mostly dead coral rock and sandy rubble bottom (Ref. 9710, 57688). Solitary (Ref. 90102).

Estimates based on models
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
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
Nutrients (Ref. 124155
): Calcium = 255 [118, 609] mg/100g ; Iron = 1.13 [0.60, 2.16] mg/100g ; Protein = 18.4 [16.5, 20.2] % ; Omega3 = 0.188 [0.087, 0.367] g/100g ; Selenium = 20.5 [9.3, 45.4] μg/100g ; VitaminA = 153 [41, 511] μg/100g ; Zinc = 2.42 [1.41, 3.97] mg/100g (wet weight);
