Marine; reef-associated; depth range 1 - 53 m (Ref. 9710), usually 1 - 50 m (Ref. 27115). Tropical; 22°C - 27°C (Ref. 27115)
Western Atlantic: Bahamas and the Lesser Antilles to the northern coast of South America. Also Antilles and western Caribbean (Ref. 26938).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 4.0 cm TL male/unsexed; (Ref. 26340)
soft rays: 11 - 12. Yellow stripe in front of each eye, joining near tip of snout to form V. Mouth inferior; snout overhangs upper lip, connected by frenum (Ref. 26938). A black stripe beginning on snout, passing through lower part of eye, across upper end of gill opening onto body where it broadens and continues along lower side to end of caudal fin (Ref. 13442).
Inhabits coral reefs with clear waters, preferably in oceanic, insular areas (Ref. 13928). In pairs near coral heads. Monogamous (Ref. 52884). A cleaner (Ref. 9710). Minimum depth reported from Ref. 27115. Has been reared in captivity (Ref. 35420). Feeds on ectoparasites of fishes (Ref. 13442).
