Justification:
While there have been no declines documented, Chaetodon collares feeds on live coral and may be susceptible to extensive coral loss. However, it has a wide distribution and persists in marginal coral reef habitats. There are no obvious major threats beyond coral loss. It is listed as Least Concern.

Geographic Range [top]

Range Description: This Indo-Pacific species is distributed from the southern portion of the Arabian Peninsula, the Gulf of Oman and Maldive Islands in the east to the Indo-Malayan region, the Spratley Islands and the Philippines (Allen 1980, Pyle 2001, G.R. Allen pers. comm. 2006). It is usually found at depths from 1-20 m.

Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: This species occurs on rocky shoreline reefs and coral-rich outer reefs in relatively shallow water (Allen 1980, G.R. Allen pers. comm. 2006). It is usually seen in pairs, but can form large aggregations. It feeds predominantly on coral polyps when available, but also occurs in areas where coral is scarce (Allen 1980, Pyle 2001, G.R. Allen pers. comm. 2006).
Systems: Marine

Threats [top]

Major Threat(s): This species feeds on live coral, and may therefore decline in abundance following climate-induced coral depletion (Pratchett et al. 2008). However, it naturally occurs in coastal habitats with limited coral, where it appears to feed on algae (Allen et al. 1998). There have been no documented declines in the abundance of C. collare associated with coral loss, and there appear to be no other major threats to this species.

Conservation Actions [top]

Conservation Actions: There appear to be no species-specific conservation measures in place. This species is likely present within marine protected areas. Ongoing monitoring of  catches by aquarium collectors is required. Research is required to establish its specific dietary requirements and reliance on coral.
