Etymology: Neolamprologus: Greek, neos = new + Greek,lampros = torch + Greek, lagos = hare (Ref. 45335); walteri: Named after Water Dieckhoff, who first recognized this species as an undescribed species, and it has been referred to as 'walteri' in the aquarium trade for two decades (Ref. 74422).
Eponymy: Horst Walter Dieckhoff is a German cichlid aquarist who discovered, photographed, and filmed many new cichlids in the Great Lakes of Africa. (Ref. 128868), visit book page.

Highly stenotopic, restricted to rocky habitat and prefers sheltered areas; habitat features gentle slopes with small stones or rubble, cemented by calcite, with fine sediment in spaces between rubble, and stones with stromatolite growth; often associated with bivalve shell accumulations covering large areas (always Pleiodon spekii), shells are cemented together and provide many small spaces for refuge and breeding; most common at 7 to 15 m depth and locally very abundant; excavates crevices that function as refuges; substrate spawner forming large congregations; ingests sediment or plankton; poor disperser; home range 20-200 cm in diameter (Ref. 74422).
