Pterocaesio tile, common name Dark-banded fusilier, Blue-streak Fusilier, Bartail fusilier and Neon Fusilier, is a fish belonging to the family Caesionidae. Pterocaesio tile can reach a length of 25 centimetres (9.8 in). The back of the body is dark blue, while the flanks show a bluish green strike with a black stripe along the lateral line. The lower third of the body varies from white to pinkish. The lower half of the body turns bright red at night (hence the common name Neon Fusilier). It is oviparous and non-migratory. Pterocaesio tile feeds on zooplankton and is relatively rare.
