An ancient group of freshwater fishes (popularly called Bony-Tongues) represented in South East Asia and Australia by the Dragon Fishes and Barramundis (Scleropages), in South America by the Arawanas (Osteoglossus) and Arapaima or Pirarucu (Arapaima gigas), and in Africa by Heterotis. They are characterised by their bony head, large, plate-like scales, and amongst other things, a distinctly bony tongue (hence the family name).
This releasee from the aquarium trade has a good potential of becoming established, especially in the catchment reservoirs. It is usually kept alone in large tanks as it is highly territorial, but fairly hardy. Three colour varieties are recognised by aquarists, the red, the golden and the green; of which, the red variety is the most expensive. At present, this majestic fish is banned from sale as it is an endangered species. The fish is able to breathe atmospheric oxygen to some degree.
