Colour of male dark reddish brown anteriorly with a bright green dot at top end of line from mouth through eye to top of opercular opening; female red on head, belly and fins, side with wavy black and white stripes, and dark green bands around the mouth and eye (Ref. 9793, 90102).

Biologie     Verklarende woordenlijst (bv. epibenthic)

Adults inhabit lagoon and seaward reefs (Ref. 1602), in slopes and drop-offs (Ref. 48636), often solitary but may sometimes occur in small groups (Ref. 9710, 48636). Males common in atolls where they live mainly around the inner and outer edges of barrier reefs at depths of about 30 ft; females prefer deeper habitat (Ref. 4821). Small juveniles in groups are found inshore on algae reef habitat (Ref. 9710, 48636) and sometimes enter silty, murky environments (Ref. 5490). Feed by scraping algae from rocks and corals (Ref. 5227). Are protogynous hermaphrodites (Ref. 55367). Caught with nets and other types of artisanal gear. Marketed fresh (Ref. 5284). In the Hong Kong live fish markets (Ref. 27253). Minimum depth reported from Ref. 90102.
