While there have been no declines documented, Chaetodon pelewensis generally feeds on live coral, which may make it susceptible to extensive coral loss. However, it has a wide distribution, apparently large population and no obvious major threats other than coral loss. It is listed as Least Concern.
|Range Description:||Found in the Southern Pacific Ocean, from Papua New Guinea to the Tuamotu Archipelag, south to Lord Howe Island. Abundant on the Great Barrier Reef and in the Coral Sea (G.R. Allen pers. comm. 2006). It is found from 1-45 m in depth. Range size ~19.7 million km2, from values estimated by Jones et al. (2002) based on projection of distribution maps from Allen et al. (1998).|

It is generally common with stable populations (G.R. Allen pers. comm. 2006).
Currently the most abundant species in Moorea, French Polynesia (mean of 4.1 individuals per 200 m2) and has increased in abundance over time due to increasing abundance of Pocillopora at this location (Berumen and Pratchett 2006)
|Habitat and Ecology:||Inhabits coral reefs to at least 45 m and forms pairs (Pyle 2001). Feeds mostly on coral polyps, but also consumes benthic invertebrates (G.R. Allen pers. comm. 2006). Unlike most corallivorous butterflyfishes, it tends to prefer Pocillopora over Acropora (Berumen and Pratchett 2006).|
|Major Threat(s):||This species relies on live coral for food and/or recruitment, and may therefore decline in abundance following climate-induced coral depletion (Pratchett et al. 2008). Currently this is not considered a threat, and there appear to be no other major threats to this species.|
There appear to be no species-specific conservation measures in place. This species is 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.
Further research is required to address issues of hybridization between C. pelewensis and C. punctofasciatus.
