Copella is a genus of freshwater fish belonging to the family Lebiasinidae, native to South America, known colloquially to aquarists as splashing tetras or splash tetras, because of the unique reproductive method of the best-known representative of the genus, Copella arnoldi. They are not as closely related to the tetras proper in the Characidae as initially believed.
Copella species are found in assorted slow-moving tributaries in the Amazon basin, Orinoco and The Guianas.
