Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 10 - 95 m (Ref. 58302), usually 24 - ? m. Tropical
Indo-West Pacific: widespread, from the Gulf of Aden and Oman along the East African
coast to South Africa to the Tuamotu archipelago, north-eastward to the Johnston Atoll and Hawaii, northward up to Ogasawara Island, southward through the Coral Sea down to New South Wales, Australia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 8.4 cm TL male/unsexed; (Ref. 30840)
This species differs from its congeners in having an almost transparent (except for
a dark anterior part of the dorsal- and ventral margin), slightly whitish to yellowish caudal fin
versus the dark blue caudal fin in C. argi and C. aurantonotus or a bright yellow to orange caudal fin with a dark blue distal margin in C. resplendens Ref. 53274).
Benthopelagic species found in reefs (Ref. 58302); in coral bottoms of channels and over reef slopes (Ref. 9710); also in areas with rubble bottom (Ref. 4858). Often in small loose groups on inner reefs in low patches of brittle corals and coralline algae mix that is shared by damselfishes and small wrasses (Ref. 48636). Herbivorous (Ref. 33482). Occasionally exported through the aquarium trade (Ref. 48391).
