Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1

This species is widespread thoughout the Indo-Pacific. It is rare in the Philippines, Indonesia and Malaysia and a major threat is the collection for the aquarium trade. There is also habitat degradation in these regions. However, due to the wide range and life history of this species the global population is thought not to reach any of the thresholds for threatened categories. This species is listed as Least Concern. A regional assessment for the Indo-Malay Archipeligo may show a threatened category if assessed.

Population [top]

Population:There is no population information for this species. It is rare in Malaysia, Indonesia the Philippines (Allen 2006, A. Cabanban pers. comm. 2008). It is common in western Australia.

On the east coast of Peninsular Malaysia, an estimated mean density of 0.75 individuals from twenty 50 m X 5 m transects was recorded in underwater fish visual surveys (Yusuf et al. 2002).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is found in coral reefs on coastal to outer reef crests. In Japan, it is found in areas of mixed sand, rock and coral (Lieske and Myers 1994). It occurs in small groups to about 20 m depth (Kuiter and Tonozuka 2001). They aggregate to spawn (L. Squire and M. Samoilys in Russel 2000). Allen (2006) found them in a group of four at 10 m (schooling).

It feeds by sorting small animals from mouthfuls of sand and detritus.

Use and Trade [top]

Use and Trade: This species is collected for the aquarium trade.

Threats [top]

Major Threat(s): A major threat is the degradation of the coral reef habitat. This species is collected for the aquarium trade, which is considered a threat due to the fact that they are rare.

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. There is some protection through the Marine Aquarium Council standards and certification and from quota regulations in Australia for aquarium fishes.
