Habitat and Ecology:
Inhabits inner reef flats, in lagoons, and on moderately exposed outer reefs (depth 1-36 m, usually 1-5 m). Feeds on coral polyps, algae, polychaetes and other benthic
invertebrates. Often occurs in pairs, but may also be seen alone or in small groups. Oviparous. Form pairs during breeding. Juveniles often in small aggregations with
with similar sized juveniles of other species, especially C. kleinii.
This species is not protected or subject to fishery regulations. It may on occasion be subject to net fishing but would typically be released on capture.
C. citrinellus can be distinguished from several similar species by the black lower anal fin margin.
