Summary:

Identifying features
• Large fish (greater 100 mm SL) have bony knobs above and between the eyes, that become larger and more noticeable as the fish grows;
•  Individuals smaller than 125 mm SL have two pale bars on the sides, and often have an ocellus at the junction between the dorsal-fin spines and the soft dorsal-fin rays.

More Info


Distribution

Recorded in Australia from One Tree Island, Capricorn Group, Great Barrier Reef, Queensland, to about Sydney, New South Wales; also at Lord Howe and Norfolk islands, and Elizabeth and Middleton reefs in the Tasman Sea. Very common around Lord Howe Island and Norfolk islands.

Elsewhere found in the subtropical Southwest Pacific - northern New Zealand and New Caledonia.

Adults inhabit lagoons and outer reefs, including surge channels in depths to 40 m.

Features

Meristic features:
Dorsal fin spines/rays: X111, 17-19
Anal fin spines/rays: II, 13-14
Pectoral-fin rays: 20-22
Lateral line scales (tubed): 26-33
Gill rakers: 7 to 11 + 1 + 9 to 11 (total 17 to 23)Teeth in jaws: 48-56

Body depth 1.6 to 1.7 in SL; head length 3.2 to 3.4 in standard length; snout 2.5 to 2.7, eye 3.2 to 4.1, interorbital 2.3 to 2.8 in HL; caudal peduncle depth 1.7 to 1.9 in HL, length of caudal peduncle 3.3 to 4.0 in HL.

Colour

Juveniles (about 25-80 mm SL) with two prominent whitish bars on sides, the first from base of anterior dorsal-fin spines to behind and below the pectoral-fin base; the second from base of 9th-11th dorsal-fin spines to the anal-fin origin.

Tail base, breast and lower part of head reddish-brown; a dark brown streak on operculum; an indistinct pale band extending from nape to lower edge of gill cover; spinous dorsal fin brown to dusky, except where interrupted by extensions of pale bars on sides

Soft dorsal fin dark brown basally, translucent distally, with a pale-rimmed black ocellus between the 10th dorsal-fin spine and 2nd or 3rd soft ray; ocellus rimmed with an iridescent pale blue in juveniles. Anal and pelvic fins mostly dark brown to blackish; caudal fin dusky to translucent; pectoral fins pale with a dark spot on upper portion of fin base and frequently on lower corner. Juveniles often have yellowish fins.

The ocellus and pale bars gradually fade with growth. The ocellus usually disappears before individuals reach about 100 mm SL, and the bars are usually lost between about 110-140 mm SL. The ocellus is sometimes replaced by a whitish blotch in subadults.

At Lord Howe Island, the upper part of the head is usually yellowish in adults. In northern New South Wales mature adults may have a pale band behind the head.

Feeding

Feed mostly on algae.

Biology

The sexes are separate and males and females form pairs during the breeding season. Females lay their demersal adherent eggs onto an area or 'nest' cleared by the male. Males aggressively guard and aerate the eggs until the larvae hatch.
