Etymology: Caesio: Latin, caesius, bluish-grey, 1835; it is the same name given to the silvery metal (Cs) (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 2 - 25 m (Ref. 9710). Tropical; 31°N - 11°N, 32°E - 45°E (Ref. 402)
Indian Ocean: Red Sea to the Arabian Sea.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 35.0 cm TL male/unsexed; (Ref. 402)
soft rays: 12. With 4-5 scales on cheek; 21-24 predorsal scales; scaled dorsal and anal fins; narrow scaleless zone at dorsal midline interrupting Supra-temporal band of scales. Upper peduncular scale rows usually 11 (10-11); lower peduncular scale rows usually 14 or 15 (13-15). Most of body light to silvery blue, paler ventrally. Black blotch at the tip of each caudal-fin lobe bordered proximally by a white band. Presence of a small process on each ventrolateral surface of basioccipital for attachment of Baudelot's ligament. Post maxillary process single; posterior end of maxilla blunt.
Inhabits coastal areas, primarily on coral reefs. Forms large midwater aggregations and feeds on zooplankton. Oviparous, with numerous, small pelagic eggs (Ref. 402).
