Sunshine Peacock (Aulonocara baenschi) Breeding Guide

How to breed the Sunshine Peacock (Aulonocara baenschi), a maternal mouthbrooder from Lake Malawi: sexing, harem setup, spawning and roughly four weeks of holding.

Overview

Aulonocara baenschi is a maternal mouthbrooder endemic to Lake Malawi, recorded from Nkhomo Reef and nearby areas, where it lives over sandy zones interspersed with rocks. Males are territorial while females live in small schools. In captivity it spawns readily in a harem arrangement.

Sexing

Adult males are larger and far more colourful than females, and they carry egg-like spots on the anal fin. Females remain plainer. Fish become reliably distinguishable by sex at around four months of age.

Conditioning

House a single male with four to six females to spread his attention and reduce harassment. Condition the group well before spawning so females come into breeding condition together.

Breeding Setup

Provide flattish rocks and open areas of sand to serve as spawning sites. Keeping several females per male is the key to a stable spawning group.

Spawning Behavior & Trigger

The male establishes a spawning site and performs courtship displays. The receptive female lays eggs and immediately takes them into her mouth. She is then drawn to the egg-spots on the male's anal fin; as she attempts to collect these, the male releases milt and the eggs are fertilised inside her mouth.

Egg & Fry Care

The female incubates the brood for up to about four weeks and normally does not eat during this period. Newly released fry may still carry yolk and need no supplemental food until it is absorbed; once that happens, Artemia (brine shrimp) nauplii or similar foods can be offered. Some breeders artificially strip fry at roughly the two-week stage to rear them separately.

Common Challenges

Excessive male aggression toward a lone female is the main risk, which the harem ratio addresses. A stressed holding female may swallow or spit the brood early, so minimise disturbance during the incubation period.
