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 m (520 ft) below the surface.[2] It reaches about 10 cm (4 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 (reduced eyes and non-pigmented) found in similar habitats in the Congo River are an elephantfish (Stomatorhinus microps), a clariid catfish (Gymnallabes nops), a mochokid catfish (Chiloglanis sp.), two claroteid catfish (Notoglanidium pallidum and Platyallabes tihoni), and four spiny eels (Mastacembelus aviceps, M. brichardi, M. crassus and M. latens)[5][6][7][8]
