Chaetodon miliaris is an abundant species throughout its range. More than two thirds of its range is enclosed by the Papahanaumokuakea Marine National Monument, a no-take marine protected area. It is therefore listed as Least Concern.
|Range Description:||This species is endemic to the Hawaiian Islands and Johnston Atoll (Burgess 1978, Randall 2005, G.R. Allen pers. comm. 2006). It is known to occur to at least 250 m depth.|
Native:United States (Hawaiian Is.); United States Minor Outlying Islands (Johnston I., Midway Is.)
|FAO Marine Fishing Areas:||
Pacific – eastern central; Pacific – northwest

|Population:||It is very abundant in the Hawaiian Islands, but very rare at Johnston Atoll (Allen 1980, M. Craig pers. obs. 2005, G.R. Allen pers. comm. 2006, P. Lobel pers. comm. 2007). Populations are generally stable (G.R. Allen pers. comm. 2006).|
|Habitat and Ecology:||
Habitat for this species includes coastal fringing reefs, lagoons, and outer reefs to at least 250 m depth. Juveniles are found on shallow inner reefs from April to June. The species feeds in mid-water on zooplankton, supplementing the diet with benthic invertebrates (especially polychaete worms) and fish eggs (particularly those of damselfishes) (G.R. Allen pers. comm. 2006).
The species may form large groups and spawns in groups from January through May (Ralston 1981). Ralston (1976a) reported that the onset of reproductive maturity in Chaetodon miliaris begins at 90 mm standard length, which is equivalent to one year of age (Ralston 1976b).
The mean size of C. miliaris in Hawaii reported by Ralston (1981) was ~105 mm corresponding to approximately two years of age.
There appear to be no major threats to this species. Collection is limited and is not considered to be impacting the global population.
There are no species-specific conservation measures in place (Hawaii Division of Aquatic Resources.). It is present within marine protected areas, for example, the Papahānaumokuākea Marine National Monument, a no-take marine reserve that encompasses 2/3 of the species range.
