The Oscar Fish is a tropical cichlid native to the Amazonian basin region of South America. It can be found in regions ranging from the upper Amazon, down to the Rio Tocantins. The Oscar can also be found living naturally in Surinam and French Guyana. Due to its colouration it's sometimes known as the marble or velvet cichlid, however I doubt whether you will find it being sold under these names. The Oscar has the potential to exceed 14 inches in length and weigh up to 3lb in weight. However, expect an aquarium housed Oscar to reach sizes of around 11-12 inches.
The Oscar is definitely one of the more intelligent aquarium fish that you will come across, they seem to have the ability to recognize their owners and almost seem to be aware of what is going on outside of their aquarium. Feeding time is always fun as the Oscar really does live for food and dinnertime.
