Caesio teres, the yellow and blueback fusilier, beautiful fusilier, blue and gold fusilier or yellow-tail fusilier, is a species of marine, pelagicray-finned fish belonging to the familyCaesionidae. It occurs in the Indian and Western Pacific Oceans.
Caesio teres has a moderately deep, fusiform and laterally compressed body. The dorsal fin has 10 spines and 14-16, typically 15, soft rays while the anal fin contains 3 spines and 12-13 soft rays. The pectoral fins contain 20-22, typically 21 rays.[5] This species attains a maximum total length of 40 cm (16 in), although 26.6 cm (10.5 in) is more typical.[3] The upper back and the rear part of the dorsal fin are bright yellow with the remainder of the body being bright blue on the upper body and white ventrally. The pectoral fin is white with a black upper base, the pelvic and anal fins are white.[7]
Caesio teres feeds on zooplankton.[3] It is diurnal, and lives in groups and forms schools with other species of fusiliers such as Caesio xanthonota.[5]The adults migrate to defined areas in The vicinity of the reef where they spawn close to the surface over and in the openings of deep channels during ebbing tides, the timing being governed by lunar cycles. It is an oviparous species which lays large numbers of small, pelagic eggs. [3]
