Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 2.4 cm SL male/unsexed; (Ref. 52975)
Dorsal spines (total): 7; Dorsal soft rays (total): 8 - 9; Anal spines: 1; Anal soft rays: 8 - 9. Diagnosis: Seven large regular orange red bars along the side of the body; a dark spot on the lower base of the pectoral fin, and another on the lower peduncle; internal pigmentation on the dorsal surface of the head just behind eyes well-developed but broadly diffused, not forming a discreet bar. Predorsal scales absent. Second dorsal spine slightly to very elongate. A moderate interorbital and variably-developed postorbital trench. The fifth pelvic fin ray is unbranched and 50-70% of the length of the fourth.
Inhabits coral reefs in 0-40 m (Ref. 90102).

Estimates based on models
Preferred temperature (Ref.
123201): 26.5 - 29, mean 27.7 °C (based on 138 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).
