From The Aquarium Wiki
Erythrinidae, also known as Trahiras, are a family of freshwater fish found in the rivers of South America. There are 3 genera and 14 species in this family belonging to the order Characiformes. They are very common and are usually caught with hooks by fishermen, partially because of their voracious behaviour. Some of these fish are predators. Others have the ability to breathe air and move over land between ponds.
