Tetra is the common name for various small, often colorful, tropical, freshwater fish within the two characiform (order Characiformes) families Characidae—and in particularly its subfamilyTetragonopterinae, the "South American tetras"—and Alestiidae, the "African tetras." The African tetras formerly were classified in Alestiinae as a subfamily of Characidae, and remain within Characidae in some classifications.
The term tetra is not a formal taxonomic rank, but rather is the common name used for numerous small fish scattered over numerous genera and different families and subfamilies. Because of the popularity of tetras in the fish-keeping hobby
