Way of life
Neolamprologus tetracanthus occurs close to the coast on all shores of Lake Tanganyika with free sandy soils. The species feeds mainly on snails, but also on fish and insect larvae. Snails that the fish cannot crack open with their jaws are sucked out of their shells. Spawning takes place in sand pits that the fish dig into the ground. The brood, which consists of several hundred fry, is led and guarded by both parents.
