Taggstrålar i ryggfenan (totalt) : 1; Mjukstrålar i ryggfenan (totalt) : 25 - 27; Taggstrålar i analfenan: 1; Mjukstrålar i analfenan: 17 - 19. Dorsal fin of males generally dusky when preserved, the large dark spot absent on anterior part of fin. Caudal vertebrae, 23-25 (usually 24). Anterior lateral line scales 32-39, usually 33-37. Posterior interorbital pores 1-2; total parietal pores 14-30, usually more than 30 (Ref. 42958).

Apparently living in corals with surfaces composed of tiny finger-like projections (Ref. 42958).

Bi-directional sex change has been proposed for this species though histological analysis of more specimens is needed for confirmation (Ref. 103751).

Estimates based on models

Preferred temperature (Ref. 123201): 26.3 - 28.4, mean 27.5 °C (based on 141 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.6 ±0.58 se; based on food items.

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
