Nannaethiops unitaeniatus is a small African characiform (family Distichodontidae) widespread in tropical Africa. The species reaches only about 6 cm and has a slender, brownish to golden body with a single dark, gold-edged longitudinal stripe and a complete lateral line. It lives in schools in vegetated streams and rivers and feeds on worms, crustaceans and insects. Owing to its attractive colours and peaceful behaviour the species is popular in the aquarium hobby. It is harmless to humans and, because of its small size, of no fishery value.
