A Tetra is any of a number of species of small South American freshwater fish belonging to the family Characidae and to its former subfamily Alestiidae ("African tetras"). Many of these, such as the neon tetra, are brightly colored and easy to keep in captivity, and extremely popular for home aquaria.
Though the list below is sorted by common name, in a number of cases, the common name is applied to different species, depending on country and context. Since the aquarium trade may use a different name for the same specis, advanced aquarists tend to use scientific names for the less-common tetras.
