Μέγεθος / Βάρος / Age
Maturity: Lm ? range ? - ? cm
Max length : 30.0 cm SL αρσενικό/απροσδιόριστο; (Ref. 48637)
Ραχιαίες άκανθες (συνολικά) : 5; Μαλακές ραχιαίες ακτίνες (συνολικά) : 28 - 30; Εδρικές άκανθες: 2; Μαλακές εδρικές ακτίνες: 28. Fresh specimens with yellow caudal fin and blackish peduncular plate; preserved specimens uniform grey in color and dark fins (pectorals pale). Oblique groove on side of snout below nostrils, its length about equal to length of naked area enclosing nostrils (Ref 9808).
Inhabits coastal to outer reef slopes, usually swimming along upper edges of drop-offs in small schools (Ref. 48637). Descends from the water column to the reef front to be cleaned by Labroides dimidiatus (Ref. 4974). Feeds on benthic algae (Ref. 3145). Forms aggregations, feeding on zooplankton well above the bottom over or in the immediate vicinity of reefs. Males exhibit rapid and striking changes in color pattern during courtship (Ref. 10671).
