Goldsash Fusilier

Found in large, mid-water feeding schools, during the day often with Caesio variliniata, over coral 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.
