Distribution

Knwon in Australian waters from Noosa (Queensland) to Port Phillip (Victoria), and seamounts and rises in the Tasman Sea, including Lord Howe and Norfolk Islands, in depths of 6-60 metres.

Elsewhere in the south-west Pacific (New Zealand, Kermadec Islands, Rapa, Easter Island).

Colour

The Eastern Pigfish has two colour phases. Females are pinkish above and creamy-white to yellowish below, with many fine stripes along the body and 3 horizontal rows of large red dashes, one running below the dorsal fin and the other two originating from the eye.

Males are red above and somewhat bluish below, with a large creamish blotch below the rear of the dorsal fin that extends onto the lower soft dorsal-fin rays, and a large black blotch with a blue margin on the middle of the dorsal fin.

During the breeding season, males develop a whitish "v-shaped" marking behind the eye, darker colouring on the sides of the body, and pale upper and lower margins on the caudal fin.

Feeding

Carnivore - feeds on a range of large benthic invertebrates.

Biology

Eastern Pigfish are a long-lived wrasse, protogynous hermaphrodite, and change sex from female to male at 25-30 cm. Females are sexually at 2, male sexualy mature at 4 years. Spawns
