African tetras (family Alestidae, formerly spelled Alestiidae) are a group of characiform fish found exclusively in Africa. This family contains about 18 genera and 119 species. Among the best known members are the Congo tetra and African tigerfish; both are kept in aquaria, and tigerfish are utilized for food and as gamefish.
Although currently native only to African waterways, fossil evidence suggests that during the Paleogene, they ranged as far north as southern Europe and as far east as the Arabian subcontinent. Fossil remains date back to potentially the Late Paleocene with Hydrocynus remains known from Algeria. Alestid-like teeth are also known from the Late Cretaceous (Maastrichtian) of France, and phylogenetic evidence also suggests that they diverged around this time.
