Saulosi cichlid

About this species

The currently accepted name is Chindongo saulosi (Konings, 1990). Eschmeyer’s Catalog of Fishes confirms this combination; Pseudotropheus saulosi is the familiar former name still seen in aquarium books and shops. Use it as a search synonym, not as a separate species.

Natural habitat

The species is endemic to Taiwan(e)e Reef, a rocky reef in Lake Malawi northwest of Chizumulu Island. FishBase describes groups in the upper, sediment-free rocky zone, where currents are strong. The fish pick food from the biocover on rocks.

The IUCN assessment displayed by FishBase is Critically Endangered (CR), assessed in 2018. Its natural range is extremely small, and aquarium collection historically contributed to pressure on the population. Treat this as care guidance for existing captive stock: choose traceable captive-bred fish and do not buy wild-caught animals.

Aquarium and layout

Recommendations vary from about 128 litres to 150–200 litres, and from roughly 100 to 120 cm in tank length. Because Saulosi are territorial and limited shelter can intensify conflict, this guide uses about 200 litres and 120 cm as a cautious baseline. It is a planning recommendation, not a guarantee that every group will thrive together.

Build a stable rock structure with multiple caves, crevices and broken sightlines, while leaving open swimming space. Use sand or another fine substrate, strong filtration and good oxygenation. Secure rocks against digging fish to prevent collapse. Plants are not characteristic of the natural rocky reef and may be uprooted or damaged.

Water conditions

FishBase records natural conditions of 23–27 °C and pH 7.4–8.4. AquaInfo recommends 24–28 °C and pH 7.6–8.8 for aquarium care. We therefore show 24–27 °C and pH 7.6–8.4 as cautious working values consistent with both source ranges.

For GH, FishBase lists 7–30 dH and AquaInfo 10–25 dH; this guide shows 10–25 °dGH as an aquarium-oriented range. Keep the water hard, alkaline and above all stable. GH and KH are different measurements; do not make rapid adjustments to chase one target number.

Behaviour and group size

Saulosi is a territorial, rock-dwelling mbuna. An adult male may defend a site and repeatedly chase subordinate fish if the layout or group composition is unsuitable. A cichlid-focused source recommends a group and suggests starting with six juveniles; the eventual sex ratio and group size depend on behaviour and are not guaranteed by that starting point.

This is not a standard community fish. Avoid similarly dominant mbuna in small or sparsely furnished aquariums. If an experienced keeper mixes species, provide ample room, separate rock territories and several feeding points. Intervene if fish stop feeding, hide continuously or are injured.

Feeding

When keeping a group, spread small portions across several spots so subordinate fish can feed too. Offer only what is eaten promptly and remove leftovers to limit unnecessary waste and protect water quality.

Breeding

Chindongo saulosi is a maternal mouthbrooder. After spawning, the female collects the eggs in her mouth and protects the young there during early development. Timing and brood size vary; no fixed number of fry is guaranteed.

Leave a brooding female undisturbed where possible and do not routinely catch her. Young fish are yellow; males gradually develop blue colour and dark bars as they mature. Breed only from responsibly sourced captive stock and avoid mixing provenance lines when they are known.
