Lamprologus lethops is a species of cichlid fish from areas with fast current in the Congo River in Central Africa, where it is believed to live in depths as great as 160 metres (520 ft) below the surface.[2] It reaches about 10 centimetres (3.9 in) in length, is all whitish (non-pigmented) and blind.[3] Living L. lethops were seen for the first time in 2011 when local fishermen managed to bring up a few specimens alive from the depths. They have subsequently been kept in aquaria.[4]

Among other fish species with similar adaptations (blind and non-pigmented) found in similar habitats in the Congo River are a clariid catfish (Gymnallabes nops), a mochokid catfish (Chiloglanis sp.) and two spiny eels (Mastacembelus brichardi and M. crassus)[5][6][7]
