Yellowback fusilier

The Yellowback fusilier (Caesio xanthonota) is a vibrantly colored fish, predominantly blue with a distinct yellow upper body and tail. It originates from the Indo-Pacific region, including areas from the Maldives to the western Pacific Ocean. This species features a sleek, streamlined body shape typical of fusiliers. While it is known for its striking appearance, the Yellowback fusilier is not particularly well-known in the aquarium hobby, primarily due to its size and the specific requirements needed to maintain it in captivity.
