Lepidiolamprologus cunningtoni Breeding Guide

How to breed the large Tanganyika predator Lepidiolamprologus cunningtoni: large sand crater nests, careful pairing and substrate spawning in a big tank.

Overview

Lepidiolamprologus cunningtoni is a large predatory cichlid endemic to Lake Tanganyika, reaching about 29.1 cm TL. It is usually solitary, swims close to the sand bottom and preys on fish, including smaller cichlids. It digs large crater-shaped nests in the sand even where rocky shelters are available, indicating a substrate-spawning habit.

Sexing

Sexing is not well documented; as with related Lepidiolamprologus, pairs are most reliably recognised by behaviour once a nesting territory is established.

Conditioning

As a piscivore preying on smaller cichlids, the species is conditioned on meaty foods. Its predatory, solitary nature means pairing must be managed carefully in a very large tank.

Breeding Setup

A very large tank with extensive open sand is required so the fish can excavate its large crater nest. Maintain hard alkaline Tanganyika water around pH 7.5-8.0, hardness 25-30 dH and 24-27 C, as reported for the species.

Spawning Behavior & Trigger

The species constructs a large crater-shaped nest in the sand, preferring this even when rocks that could serve as shelter are nearby, and spawns within the excavated site as a substrate spawner. Breeding in aquaria is not well documented.

Common Challenges

This is a large, aggressive predator that will hunt smaller cichlids and shellies, so it needs a very large tank, careful tankmate selection and ample open sand. Stable warm, hard, alkaline water is essential.
