Height 4.5-4.6, 5.2 in length with caudal. Head 3.4-3.8, 4-4.2 in length with caudal. Height of head 1.6-1.8 in its length. Eye 4.6-4.8, 1.3-1.7 in snout and 1.1-1.4 in somewhat convex inter orbital space. Mouth very small, horizontal. Lips swollen, the upper one with a median furrow, the lower one separated in two by a median frenulum and produced into lobe. Small pointed teeth in a crowded row in both jaws, in several rows near symphysis. Two somewhat curved canines anteriorly in each jaw. A canine at corner of mouth. Head naked, with exception of the superior and posterior part of the preopercle and the opercle. On upper part of head the scales begin far behind eye. About 14 rows of scales before dorsal. Dorsal spines pungent, short, the first about as long as eye, the last one eye diameter and a half. Soft dorsal higher than spinous part, the longest ray equal to snout and eye together. Anal spines slender, pungent. The first about half as long as the the second, the third longest, almost equal to snout and eye together. Soft anal similar to soft dorsal. Caudal truncate or slightly rounded. Pectorals as long as head with out snout. Verticals pointed, equal to snout and eye together. Scales on lateral line: 50-52 (+2 past hypural). Dorsal spines (total): 9-9; dorsal soft rays (total): 10-11; anal soft rays: 10.

Monogamous, protogynous hermaphrodite, external fertilization, nonguarders, open water/substratum egg scatterers. Pelagic spawners. Sex reversal is completed in 14-18 days. A monandric species. Length at sex change is 8.8 cm TL.

Max. age reported: 4 years

Stays in stations where other fish come to be cleaned. Cleaning intensity is not related to client size or commonness. Cleaning stations are occupied by a pair of adults, a group of juveniles or a group of females accompanied by a dominant male where a female becomes a functional male if the dominant male disappears. Some adults solitary and territorial. An unfamiliar visitor is usually greeted by dance-like movements with the tail maneuvering the back part of the body up and down. Juveniles behave this way when divers approach closely. A small body size and the presence of a lateral stripes both contribute as long-distance signals of cleaning services for fish clients.
