Etymology: Labroides:Greek, labrax, -akos = a fish, Dicentrarchus labrax + Greek, suffix, oides = similar to (Ref. 45335). More on author: Valenciennes.
Umwelt: Milieu / Klimazone / Tiefenbereich / Verbreitungsgebiet Ökologie
Indo-Pacific: Persian Gulf (Ref.80050); Red Sea and East Africa (Ref. 4392) to the Line, Marquesas, and Ducie islands, north to southern Japan, south to Lord Howe and Rapa islands.
Größe / Gewicht / Alter
Geschlechtsreife: Lm? range ? - ? cm Max length : 14.0 cm TL Männchen/unbestimmt; (Ref. 55367); max. veröff. Alter: 4 Jahre (Ref. 3426)
Rückenflossenstacheln (insgesamt) : 9; Rückenflossenweichstrahlen (insgesamt) : 10 - 11; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 10. Often with yellow back in deep water (Ref. 48636). Scales on lateral line: 50-52 (+2 past hypural) (Ref. 1602). Body shape (shape guide): elongated; Cross section: compressed.
Adults inhabit coral rich areas of inner lagoons and subtidal reef flats to seaward reefs (Ref. 1602). They feed on crustacean ectoparasites and mucus of other fishes (Ref. 9823, 48636). Monogamous (Ref. 52884). A protogynous hermaphrodite (Ref. 55367). Stays in stations where other fish come to be cleaned. Cleaning intensity is not related to client size or commonness (Ref. 28019). 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 (Ref. 5503). 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 (Ref. 48636). Minimum depth range of 1 meter in Ref. 27115.
Bi-directional sex change has been confirmed for this species (Ref. 103751). Oviparous, distinct pairing during breeding (Ref. 205). Pelagic spawners. Sex reversal is completed in 14-18 days (Ref. 34185, 34258). A monandric species (Ref. 55367). Length at sex change = 8.8 cm TL (Ref. 55367). Monogamous mating is observed as both facultative and social (Ref. 52884).
