This species is known for its striking golden coloration and streamlined body, which can grow up to 1 meter in length. The Brazilian golden dorado is a carnivorous fish, primarily feeding on smaller fish and invertebrates. It is popular among anglers due to its strong fighting ability and is often sought after for sport fishing. Conservation efforts are important to maintain its populations in the wild.
