Identifying features

​Marblefish have dark green to brown mottling across their body interspersed with white spots and flecks. They have a blunt head shape, a rounded body and a large tail and pectoral fins. The mouth has small, soft, blunt ‘teeth’ characteristic of a grazing and foraging habit.


These fish are common around most reefs in Tasmania down to depths of 30 metres. They graze on algae but will eat invertebrates and fish flesh if the opportunity arises.

Fishing information

Marblefish are caught both on rod and line and by gillnets set over reefs in shallow coastal areas right around Tasmania. They are strong fighters if hooked on rod and line, but are not normally targeted due to their poor eating quality.


Marblefish have sharp dorsal spines which they will erect and lock in place when captured.


These fish have a strong iodine smell when cleaned. The flesh is tough and clear and green in colour. You would probably only want to try and taste this fish once!
