While there is no information on the diet of this species it is likely to be an obligate corallivore. Coral depletion may cause some declines, but there is no data on temporal trends in the abundance of this species. This is a widespread species and common. It is listed as Least Concern.
|Range Description:||This species ranges throughout the tropical Indian Ocean from Kenya to northern South Africa on the east African Coast, Madagascar including the western and central Indian Ocean islands, Southern India, Sri Lanka, Nicobar and Andaman Islands (India) and western Thailand east to Java (G.R. Allen pers. comm. 2006). It is found at depths of 1-15 m.|

|Population:||This species is common. While it is may be reliant on live coral, there is no information on population trends for this species.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||This species occurs in areas of rich coral growth in lagoons or on seaward reefs (Allen 1980, G.R. Allen pers. comm. 2006). It is usually seen in pairs or small aggregations that may contain as many as 20 individuals (Allen 1980). There is not data on the diet of this species, but it is assumed to feed on hard and soft corals, like the sister species C. ulientensis (M. Pratchett pers. comm. 2009).|
|Use and Trade:||This species is sometimes collected for the aquarium trade (G.R. Allen pers. comm. 2006). It is frequently exported from Sri Lanka (Allen 1980).|
|Major Threat(s):||This species probably feeds on live coral, and may therefore decline in abundance following climate-induced coral depletion (Pratchett et al. 2008). Currently there have been no documented declines associated with coral loss, and there appear to be no other major threats to this species.|
|Conservation Actions:||There are no species-specific conservation measures in place for Chaetodon falcula. This species is likely to be present within marine protected areas. Monitoring of this species is needed in conjunction with coral monitoring, as well as determination of the degree of co-dependence between this species and corals. Research is needed to establish the dietary requirements for this species.|
