Habitat and Ecology [top]

Habitat and Ecology:Occurs in coral rich areas of lagoon and seaward reefs to a depth of 80 m or more. Often found in the vicinity of caves and feeds on sponges and tunicates. Juveniles are cryptic, remaining well hidden in cracks and crevices. Solitary or in pairs, or in groups (Pyle 2001).

Use and Trade [top]

Use and Trade: This species is commonly exported through the aquarium trade. It is mainly caught for export from the coastal waters of Manila (Philippines), Singapore and Sri Lanka (Steene 1978). It is a difficult species to maintain in captivity for any length of time, and often dies within six months (Steene 1978).

Threats [top]
