Yellow and blueback fusilier

📖 Overview

Adults are found primarily around coral reefs, with a preference for coralline lagoons. They feed on zooplankton in large midwater groups and form schools with other caesionids. Mature adults migrate to select areas around the reef to spawn near the surface in the entrances of deep channels during outgoing tides on a lunar cycle. They are oviparous, with numerous, small pelagic eggs . Are caught with drive-in nets. Maximum depth reported taken from Ref. 128797.
