Facts and Information
Thanks the aquarium hobby, the once lowly Oscar has been elevated from a common South American food fish to beloved pet around the world. Oscars are one of the few fish to display owner recognition, meaning they know the hand that feeds them. They are also somewhat temperamental when it comes to changes in their environment and will rearrange the tank to their liking if they find it unsuitable. Many Oscars display behaviors that can't be labeled as anything other than "pouting" when a favorite rock or log is removed. They often refuse food and lay sideways on the bottom of the tank, generally looking disinterested in anything going on. Once the item is replaced, they return to their normal behavior.
