From HandWiki
Acestrorhamphidae, the American tetras, are a diverse family of freshwater fish in the order Characiformes. They are native to North and South America, from the southwestern United States south to temperate Argentina, with a few species introduced to other parts of the world. It includes many genera previously placed in the family Characidae, which was split into multiple families in 2024. It contains many of the most famous ornamental aquarium fish that are popularly known as tetras.[1][2][3]
