Easily recognisable by its colouration, this small sized fish is also known as the Clown Triggerfish and is widely distributed throughout the tropical and subtropical waters of the Indian Ocean until the western Pacific Ocean, and also the Caribbean.

Most commonly found along external reef slopes with clear water, in Australia it is known from the offshore reefs of north-western Western Australia and from the northern Great Barrier Reef to northern New South Wales.

The triggerfish has a diurnal activity, is solitary and defends a territory. It can be very aggressive with other fish and congeners. The first long dorsal spine when erected is used to impress and opponent or to avoid a predator.

The hardyhead feeds on a range of small crustaceans, polychaete worms, gastropod molluscs, insects and insect larvae, foraminiferans, and plant matter.

Also known as the Indo-Pacific tarpon, this species is widely distributed from Australia, Japan and North Africa. The tarpon lives in many tropical areas of Australia in the tropical, coastal, and brackish waters of the Indo-Pacific oceans, and in both freshwater and saltwater.

They inhabit coral reefs, mangroves, swamps, rivers, lakes, reservoirs, floodplains, and canals. They are opportunistic feeders, feeding on smaller fish, crustaceans, and even plants. In saltwater, they mainly feed on prawns and herring, but also many other small fish.
