Nyasa Blue Cichlid, Zebra M (Maylandia zebra (syn. Pseudotropheus zebra)) — 4-5cm

Overview

The Zebra Mbuna (Maylandia zebra, syn. Pseudotropheus zebra), also known as the Nyasa Blue Cichlid, is one of Lake Malawi's most iconic and popular rock-dwelling cichlids. Prized for its vivid blue-and-black barring, lively personality, and hardy nature, this mbuna thrives in hard, alkaline water and rewards dedicated aquarists with stunning colour displays and fascinating mouthbrooding behaviour. With an adult size of around 11.3 cm, M. zebra is ideally suited to well-planned Malawi mbuna aquariums.

Appearance

Maylandia zebra displays striking vertical blue-and-black bars that create a bold, high-contrast pattern. Colour morphs vary widely, with individuals ranging from solid blue to barred blue-and-black, depending on locality and breeding line. Males are typically more intensely coloured with brighter blues and more defined barring, while females are often more subdued. The body is robust and stocky, with well-proportioned fins and a strong jaw adapted for grazing on aufwuchs (algae and microorganisms) on rocks.

Natural Habitat

This species is endemic to Lake Malawi, where it inhabits rocky shorelines and boulder fields at shallow to moderate depths. The lake's ancient, stable chemistry—characterised by high mineral content, exceptional clarity, and warm temperatures—has shaped the evolution of hundreds of endemic cichlid species. In nature, Zebra Mbuna graze on aufwuchs, defend small territories among rocks, and engage in complex social and breeding behaviours.

Aquarium Setup

Recreate a Malawi mbuna biotope with plenty of rockwork arranged to form caves, crevices, and line-of-sight breaks. Use a sandy or fine gravel substrate and ensure stable water chemistry: pH 7.5–8.6, hard water (GH 10–20°), and a temperature of 24–28°C. A minimum of 150 litres is recommended for a small group, with larger tanks supporting additional tankmates. Provide strong filtration, regular water changes, and moderate lighting to encourage natural grazing behaviour on algae-covered rocks.

Water Parameters

Like all Malawi mbuna, the Zebra Mbuna demands pristine, stable conditions. Aim for 24–28°C, pH 7.5–8.6, and high hardness. Conduct weekly partial water changes (20–30%) to maintain low nitrate levels and replenish essential minerals. Use a high-quality filter rated for the tank volume, and consider adding crushed coral or Malawi cichlid salts to buffer water chemistry. Stability is critical—avoid sudden fluctuations in temperature or pH.

Feeding

This species is a primarily herbivorous grazer that feeds on aufwuchs and algae in the wild. In captivity, offer spirulina-based flakes or pellets, blanched vegetables (such as spinach, courgette), and occasional protein-rich foods in moderation to avoid digestive issues. Avoid high-protein diets, which can lead to bloating and Malawi bloat disease. Feed small portions once or twice daily. A balanced, algae-rich diet supports vibrant coloration, healthy growth, and successful breeding.

Behaviour

Zebra Mbuna are aggressive and highly territorial, especially when guarding a chosen territory or preparing to spawn. Males establish and defend territories vigorously, and may become particularly assertive towards rivals and other tankmates. This species is best suited to a Malawi mbuna setup with robust, similarly sized cichlids and plenty of rockwork to establish territories and line-of-sight breaks. Careful stocking and observation are essential to reduce aggression.

Tank Mates

Suitable companions include other Lake Malawi mbuna of similar size and temperament, such as Pseudotropheus, Melanochromis, or Labidochromis species. Robust, fast-moving cichlids from Lake Malawi and species that tolerate hard, alkaline water and can hold their own are also compatible. Avoid small peaceful fish, slow-moving fish, long-finned species, shrimp and other small invertebrates, or aggressive species that are much larger or more dominant. Careful planning and adequate space ensure a harmonious mbuna community.

Breeding

Maylandia zebra is a maternal mouthbrooder. A dominant male courts females and the female carries the eggs and fry in her mouth for about three weeks. Provide rockwork, stable water conditions, and separate fry if needed to prevent predation by tankmates. Fry can be fed newly hatched brine shrimp or specialist fry foods once released. Stable water conditions and excellent filtration support successful breeding. Consider a species tank or carefully managed mbuna setup with multiple females per male to reduce aggression.
