Habitat and Ecology [top]

Habitat and Ecology:This species inhabits clear coastal waters to outer reef slopes and drop-offs in Australia (Kuiter 2002), over sand and rubble. It is found in depths from one to 30 m (Myers 1991, Baensch and Debelius 1997).

It forms spawning groups at 4-6 m depth, along channels or passages and promontories or bommies. It spawns from March to May and in October-November at full moon and on an ebb tide in the Marshall Islands (Colin and Bell 1991). Juvenile and adult male colour patterns differ (Kuiter 2002).

Larval duration in Hawaii was 78 days (Victor 1986).
