Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 4.0 cm TL male/unsexed; (Ref. 4343)
soft rays: 9 - 10. Head reddish-orange; body and fins black (Ref. 1602); characterized further by having ctenoid scales except cycloid on abdomen; scaleless head and nape with bristle-like papillae; complete pelvic fin frenum and basal membrane; longitudinal scale series 23-25; depth of body at level of pelvic fins 3.0-3.2 in SL (Ref. 90102).
Lives among branches of Stylophora coral. Monogamous (Ref. 52884). Usually in small groups, also found in lagoon and seaward reefs in 1-10 m (Ref 90102).
Life cycle and mating behavior

Bi-directional sex change has been confirmed for this species (Ref. 103751). Monogamous mating is observed as both obligate and social (Ref. 52884).

Estimates based on models
Preferred temperature (Ref. 115969
): 24.7 - 29, mean 27.9 °C (based on 902 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.3 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) .
