The Speckled Butterflyfish can be recognised by its colouration. It is white to yellow with numerous dots on the body. A black bar passes through the eye, and the caudal fin is transparent.
This species bears a superficial resemblance to several other species including Günther's butterflyfish Chaetodon guentheri (view fact sheet). The black lower anal fin margin of C.citrinellus distinguishes it from other species.
The Speckled Butterflyfish grows to 13cm in length.
It eats coral polyps, algae, and polychaete worms.
This species is usually found in very shallow (1-3m) coral reefs, however it is sometimes seen in water over 30m deep.
The Speckled Butterflyfish is recorded from tropical marine waters throughout the Indo-West and Central Pacific.
In Australia it is known to occur from central to north-western Western Australia and the northern Great Barrier Reef to central New South Wales.
