Neolamprologus leleupi is a species of cichlid endemic to Lake Tanganyika where it occurs throughout the lake. It is a recess-dweller, inhabiting cracks and crevices. It feeds on invertebrates living in the rich biocover of the substrate. This species reaches a length of 10 centimetres (3.9 in) TL. The color of this fish ranges from bright yellow to deep brown.
