Magpie morwong - Cheilodactylus gibbosus

Cheilodactylus gibbosus – Western Wirrah / Hump-headed Morwong

The Cheilodactylus gibbosus is a rarely-seen temperate reef species found off the coast of Western Australia. Known for its distinctive humped head profile and robust body, this fish has a bold, commanding presence in the aquarium. Its coloration ranges from silvery to dusky tones with darker mottling, allowing it to blend naturally into rocky reef environments.

In captivity, C. gibbosus is hardy and adapts well to a diet of meaty frozen foods, pellets, and live offerings. This species grows to a large size and requires a spacious aquarium with strong filtration and plenty of swimming room. While not aggressive, its size and appetite make it best suited for fish-only systems with similarly large or semi-aggressive tankmates.
