Princess of Burundi (Neolamprologus brichardi) Breeding Guide

Breeding the Princess of Burundi (Neolamprologus brichardi), a Lake Tanganyika cave spawner famous for cooperative colonies where older offspring help raise younger fry.

Overview

Neolamprologus brichardi is a Lake Tanganyika substrate spawner that, in nature, deposits its eggs on the roof of rocky caves. It is one of the few substrate-spawning cichlids that also schools, and it forms cooperative colonies in which the whole group helps guard the fry.

Sexing

Adult males are larger and have more extended dorsal and caudal fins than females, but the two sexes are otherwise similar, so allowing fish to pair naturally within a group is the simplest approach.

Conditioning

The fish swim together as a group and pair off to spawn, retaining the pair bond for future spawns. Keep a colony in hard, alkaline Tanganyikan water and condition on small invertebrate-based foods reflecting their natural diet of small crustaceans and plankton.

Breeding Setup

Provide rocky structure with caves and crevices so pairs can claim a spawning site, ideally with the cave roof and walls available as egg-laying surfaces. The species is non-aggressive away from the nest but defends the immediate breeding territory.

Spawning Behavior & Trigger

A pair deposits up to about 200 eggs (but usually far fewer) on the walls or roof of a cave. The female tends the eggs while the male guards the area around the cave.

Egg & Fry Care

Eggs hatch in two to three days and the fry become free-swimming at around the seven-day stage; they are large enough to take brine shrimp nauplii from birth but grow slowly. Brood care is long-lived and cooperative: the entire group helps the parents guard the fry, and once the parents stop protecting a brood those offspring are allowed to remain and actively help guard the next generation.

Common Challenges

Extended families coexist peacefully until space runs out, at which point crowding can trigger reproductive suppression or cannibalism of the smallest fish, so colony size must be matched to the tank.
