Neolamprologus longior

Neolamprologus longior is distinguished among shell dwellers by its noticeably more elongated body plan relative to most Neolamprologus species. The pale silver-grey body catches the light to reveal fine blue-green iridescent scaling, and the fins carry subtle banding in adults. The species occupies shallow, sandy and shell-strewn beaches throughout much of Lake Tanganyika.

Longior's behaviour follows the standard Neolamprologus template: territorial defence of a shell by the male, harem formation with two to three females, and brooding of eggs inside the female's shell. It is not as commonly exported as brevis or similis but is well regarded for its hardy constitution and willingness to eat a broad range of foods from the first day in a new tank.

This species benefits from a moderately sized aquarium of at least 60 L, a deep fine-sand substrate, and a generous provision of shells. It can be housed with other Tanganyika species that do not compete directly for the sandy benthic zone, such as Cyprichromis or Julidochromis on rockwork.
