Introduction

The Indo-Pacific Sergeant is a small tropical species that has five black bars on the body.



Identification

The Indo-Pacific Sergeant can be recognised by its distinctive colour pattern. It has a white body with five black bars. It is usually yellow dorsally. The species can be separated from the similar-looking Scissortail Sergeant by the lack of black stripes on the caudal fin.

Habitat

It is usually seen in inshore and coral reef waters.

Distribution

The Indo-Pacific Sergeant occurs in tropical and some warm temperate waters of the Indo-west and Central Pacific.

In Australia, it is known from the central coast of Western Australia, around the tropical north of the country and south on the east coast to Bass Strait.
