Pseudotropheus saulosi Breeding Guide

Breeding the dwarf mbuna Pseudotropheus saulosi, a highly productive maternal mouthbrooder from Lake Malawi with strong colour-based sexual dimorphism.

Overview

Pseudotropheus saulosi (also placed in Chindongo) is a dwarf mbuna cichlid endemic to Taiwan Reef in Lake Malawi, reaching about 8.6 cm total length. It is a maternal mouthbrooder and a highly productive one. The wild population is Critically Endangered, and captive-bred fish are being used in efforts to re-stock Taiwan Reef.

Sexing

The species shows strong colour-based sexual dimorphism. Fish are born yellow; as they mature, males turn blue with several vertical black bars, while females remain a vivid solid yellow. Some younger males can retain female coloration and only colour up and become dominant when the alpha male departs.

Breeding Setup

Maintain hard, alkaline Malawi conditions (24-27 °C, pH 7.8-8.6, GH 10-20) with a rocky aquascape that provides territories. As a rock-dwelling mbuna, it grazes algae and the small animals associated with it, so a herbivore-oriented diet supports condition for breeding.

Egg & Fry Care

After spawning the female holds the eggs in her mouth until the fry are able to swim, which normally takes 13-18 days. The species is very productive: even quite young females can produce broods of 20-25 fry, and it is not unusual to have four to five broods within just six months. Holding females may be moved to a separate tank to maximise fry survival.

Common Challenges

As with other mbuna, male aggression can be intense in confined quarters, so adequate rockwork and a suitable sex ratio are important. Given the species' Critically Endangered wild status, maintaining genetically diverse captive lines is a worthwhile goal for breeders.
