The Gold Severum, scientifically known as Heros efasciatus, is a popular South American cichlid, known for its striking gold coloration and peaceful yet semi-aggressive temperament. They are a color variation of the green Severum, with a gold or yellow body and red spots or dashes. These fish are relatively hardy and can be a beautiful addition to a community aquarium, but they do require a spacious tank due to their potential adult size of up to 8 inches.
