This fusilier grows up to 40 cm.[2] Its body is fusiform or spindle-shaped and its caudal fin is forked. The mouth is small and terminal. The protusible mouth can be extended forward to swallow food.
The body coloration is blue and yellow on the back. When this fusilier is young, the yellow area starts from the neck, or anterior part of the dorsal fin, to the low part of the caudal peduncle, drawing a diagonal. For older fish, the yellow area is reduced to the caudal fin and the caudal peduncle.[3]
