Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 2.5 cm TL male/unsexed; (Ref. 11441)
(total): 6 - 7;
soft rays: 7 - 9. Sides of nape with 8-12 scale rows (Ref. 37816); characterized further by semi-transparent body; midlateral stripe, internal reddish brown; vertebral column with white markings above; longitudinal scale series 22-28; without median predorsal scales; scaled side of nape to above preopercle; broad gill opening, reaching at least to below rear edge of eye; depth of body at anus 5.0-7.1 in SL (Ref. 90102).
Inhabit coastal reef slopes, usually on hard corals to about 30 meters depth. Sometimes found on the mantle of clams and eggs are usually laid on ascidians (Ref. 48637). Benthic (Ref. 58302). The species is generally commensal on hard corals.

Estimates based on models
Preferred temperature (Ref. 123201
): 24.8 - 29.3, mean 27.8 °C (based on 208 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00320 - 0.01497), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±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.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
