Taggstrålar i ryggfenan (totalt) : 13 - 14; Mjukstrålar i ryggfenan (totalt) : 22 - 25; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 17 - 18. Overall color is brownish yellow with vertical rows of spots forming bands on the upper portions of the sides. A black-edged orange bar runs across the eye. The posterior edge of the caudal fin is transparent. Caudal peduncle is bright orange (Ref. 4855). Snout length 2.7-4.1 in HL. Body depth 1.6-1.8 in SL (Ref. 90102).
Body shape (shape guide): short and / or deep; Cross section: compressed.
Common in coral rich areas and clear waters of lagoon and seaward reefs. Sometimes found on outer subtidal reef flats (Ref. 1602). Juveniles secretive (Ref. 48636). Feed on filamentous algae, corals, and benthic invertebrates. Often in pairs during breeding (Ref. 205), monogamous (Ref. 52884). Oviparous (Ref. 205). Occasionally hybridize with C. pelewensis in the southern part of its range (Ref. 9710). Minimum depth reported taken from Ref. 128797.

Distinct pairing (Ref. 205). Monogamous mating is observed as both obligate and social (Ref. 52884).
