Short description Morphology | Morphometrics

Dorsal spines (total): 7 - 8; Dorsal soft rays (total): 10-11; Anal spines: 1; Anal soft rays: 10 - 11. Whitish with two black stripes, one middorsal and the other lateral on head but passing to lower side on body, both ending in caudal fin; pale band separating two black stripes bright yellow on head, this band narrowing as it passes anteriorly, forming a V on top of snout with band of other side (Ref. 13442).

Found on live coral. Removes ectoparasites from other fishes. Monogamous (Ref. 52884). Has been reared in captivity (Ref. 35408).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00891 (0.00412 - 0.01928), b=3.08 (2.91 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.4 ±0.3 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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