Taxonomic Notes: Hemigymnus sexfasciatus is almost certainly a valid Red Sea endemic and sister species of H. fasciatus (Kuiter 2002). Color differences are significant and consistent and Kuiter's color photos make a convincing argument. H. sexfaciatus is not recognized by Parenti and Randall (2000) (J.H. Choat pers. comm.. 2008). A detailed comparison of specimens and genetic material is needed (R. Myers pers. comm.. 2008).

Habitat and Ecology [top]

Habitat and Ecology:This species is a small wrasse (up to 30 cm) characteristic of shallow sandy and rubble bottoms around coral reef areas with a depth range from 1-35 m. It feeds mainly on small crustaceans, molluscs and echinoderms (Westneat 2001). Juveniles are secretive on inshore reefs. Large adults swim openly on reefs, singly or in small loose aggregations (Kuiter and Tonozuka 2001). There are no demographic data available. Spawning occurs in small groups in reef passes (Colin and Bell 1991).

Use and Trade [top]

Use and Trade: This species is a minor element in the aquarium fishery (Whittingham et al. 2000, Ryan and Clarke 2005). It is also taken in some artisanal fisheries. It is a minor element in Hong Kong wet fish markets (Situ and Sadovy 2004). It is also recorded as a minor component in the Guam subsistence and recreational fisheries records (R. Myers pers. comm. 2008).

Threats [top]

Major Threat(s): There are no major threats known for this species, although it is collected for the aquarium trade and in artisanal fisheries. It is one of a large number of small widely distributed wrasses taken occasionally.

Conservation Actions [top]

Conservation Actions: There are no specific conservation measures in place for this species. Its distribution overlaps several marine protected areas within its range.
