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.
