Overview

Found in large schools, over coral reefs, in deep lagoons and seaward reefs. Varies in colour from blue to red with night and day.

Fusiliers are close relatives of snappers, but are much smaller and more slender.
Schools of fusiliers often have other species mixed in.
Although their colour is predominately yellow/blue, at night and when resting their colours change to red/green.
