Doublebar Goatfish, Parupeneus crassilabris (Valenciennes 1831)
Double-banded Goatfish, Two-banded Goatfish
The Doublebar Goatfish has been called Parupeneus bifasciatus rather than P. crassilabris in most books on Australian fishes.
Three different colour forms exist for the Doublebar Goatfish. These vary according to location.
The Indo-Australian form is pale with a dark blotch around the eye and two dark bars on the body. There is a yellow spot on each scale and sometimes a faint dark bar on the caudal peduncle. The colouration is stronger in juveniles than adults.
The Pacific form ranges from brown to red with two distinct bars.
The Indian Ocean form has two wedge-shaped bars that become progressively narrower on the belly.
Adult Doublebar Goatfish are usually seen on inshore coral reefs and in deep lagoons. Juveniles are more commonly found in surge channels near the intertidal zone. Adults and juveniles are often seen resting on coral or rubble. They occur in small groups or singularly. The species can be found at depths between 1 m and 80 m.
In Australia the Doublebar Goatfish is known from the north-western coast of Western Australia, around the tropical north, and south to the southern coast New South Wales.
