Habitat and Ecology [top]

Habitat and Ecology:A small species, to about 113 mm SL. It inhabits sandy patches adjacent to rocky reefs in depths usually to about 40 m, but may range to 100 m (Ayling and Cox 1982).

It is sexually dichromatic, social organization and sexual behavior described by Doak (1972) and Ayling and Cox (1982). A facultative cleaner symbiont (Ayling and Grace 1971) removing parasites and damaged skin and scales from other species. It also feeds on small crustaceans from the bottom and from seaweed fronds. Spawning occurs repeatedly during June-December, and juveniles (one cm) settle out on seaweed covered reefs in January-February. They mature after seven months at about seven cm TL and reach 10 cm TL after the first year. They spend one to two spawning seasons as females then in February – March many change simultaneously into males and compete for new territories.
