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).

Environment / Climate / Range Ecology

Freshwater; benthopelagic; depth range 2 - 30 m (Ref. 74422), usually 7 - 15 m (Ref. 74422).   Tropical

Biology     Glossary (e.g. epibenthic)

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).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
