Range Description:This species is widely distributed throughout much of the tropical Indo-Pacific region. It ranges from the East African coast and the Arabian Gulf in the west to the Society Islands (French Polynesia) in the east, and from southern Japan and the island of Taiwan in the north to Lord Howe Island (Australia) in the south (G.R. Allen pers. comm. 2006). It is not known from Hawaii (USA) and the Marquesas Islands (French Polynesia) (Pyle 2001). It ranges in depth from 2-75 m, usually being found below 10 m.

Population [top]

Population:It is generally common (G.R. Allen pers. comm. 2006) and the most common species of the genus (Steene 1978). There are believed to have been some localized declines in the Philippines, mostly due to aquarium collectors.
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is associated with coral and rocky reefs, and is often found in deep lagoon areas and outer reef slopes, although animals may inhabit shallower water in protected reef areas. Adults occur alone, in pairs or sometimes in small groups, almost always swimming close to the reef substrate. The species feeds mostly on plankton, but supplements this diet with benthic invertebrates. Juveniles are solitary and have been observed picking parasites from other fishes (G.R. Allen pers. comm. 2006).

Use and Trade [top]

Use and Trade: This species is the most commonly traded butterflyfish (along with Chelmon rostratus), with 42,000 individuals traded between 1988-2002 (GMAD). Individuals sell for $ 40-60 in the US (L. Rocha pers. comm. 2009).

Threats [top]

Major Threat(s): This species is intensively harvested for the aquarium industry within the Philippines (K. Carpenter pers. comm. 2009), however there appear to be no overall major threats to this widespread species (G.R. Allen pers. comm. 2006).

Conservation Actions [top]

Conservation Actions: There appear to be no species-specific conservation measures in place. This species is present within many marine protected areas. Monitoring of the population and collection levels are recommended (such as in the Philippines).
