Nyasa Blue Cichlid, Zebra M (Maylandia zebra) — 7-9cm

Overview

The Zebra Mbuna, or Maylandia zebra (formerly Pseudotropheus zebra), is one of the most iconic and widely kept Lake Malawi cichlids in the UK. Renowned for its bold blue coloration, striking vertical barring, and feisty personality, this hardy mbuna cichlid thrives in hard, alkaline water and rock-filled aquariums. Available for sale UK from Tropical Fish Co, the blue zebra cichlid is an excellent choice for aquarists seeking a vibrant, active African cichlid that brings energy and color to a well-planned mbuna community. With proper care, stable water parameters, and appropriate tankmates, Maylandia zebra is a rewarding, long-lived addition to any African cichlid setup.

Appearance

Maylandia zebra displays a brilliant electric blue body with bold black vertical bars running from head to tail. Coloration intensity varies with mood, dominance, and breeding condition—dominant males exhibit the most vivid blue and pronounced barring. Some individuals show orange or red blotches, particularly in certain geographic or selectively bred color morphs. Females are typically less colorful but still display the characteristic barring pattern. Adults reach up to 11.3 cm, with males slightly larger and more robust than females. The compact, muscular body and aggressive demeanor are typical of Lake Malawi mbuna. Juveniles are less vibrant but develop full coloration as they mature and establish social hierarchies.

Natural Habitat

Maylandia zebra is endemic to Lake Malawi, East Africa, where it inhabits rocky shoreline zones rich in algae-covered boulders and crevices. The lake's water is hard, alkaline, and exceptionally clear, with stable temperatures and high mineral content. Mbuna (meaning "rockfish") are specialized grazers that feed on aufwuchs—a biofilm of algae, diatoms, and microorganisms coating rocks. Maylandia zebra is highly territorial, with males defending feeding and spawning territories against rivals. The dense, rocky habitat provides shelter, feeding grounds, and spawning sites, all of which must be replicated in captivity.

Aquarium Setup

A minimum tank size of 189 litres (approximately 50 gallons) is recommended for a small group, though larger setups (250+ litres) are ideal for mixed mbuna communities. Provide extensive rockwork arranged to create caves, shelters, and distinct territories. Use limestone rocks, lava rock, or aquarium-safe slate to help buffer pH and maintain hard, alkaline water. Substrate should be sand or fine gravel—avoid sharp materials. Ensure powerful filtration capable of handling the bioload of these active, messy eaters. Perform frequent large water changes (30-50% weekly) to maintain water quality. Lighting should be moderate to bright. Avoid plants, as mbuna will uproot or eat them; use artificial or very hardy species like Anubias if greenery is desired.

Feeding

Maylandia zebra is a primarily herbivorous grazer adapted to feeding on aufwuchs in the wild. In captivity, provide a diet based on spirulina flakes, algae wafers, and high-quality herbivore cichlid pellets. Supplement with blanched vegetables such as spinach, zucchini, and peas. Offer small protein-rich foods (bloodworms, brine shrimp) sparingly and only occasionally—excessive protein can lead to digestive issues, bloat, and "Malawi bloat" disease. Feed small amounts 2-3 times daily, ensuring food is consumed within a few minutes. Overfeeding and poor diet are leading causes of health problems in mbuna.

Behaviour

Maylandia zebra is aggressive and highly territorial, particularly males. Dominant males establish and defend territories vigorously, chasing and nipping rivals and subdominant individuals. Aggression is most intense in cramped tanks or overstocked setups. Despite this, they are active, engaging, and colorful, making them a favorite among African cichlid enthusiasts. Females are less aggressive but still robust and competitive. These cichlids are constantly on the move, grazing, exploring, and interacting with tankmates. To reduce aggression, overstock slightly (with appropriate filtration) to spread out territorial behavior, and provide ample rockwork with multiple territories and sight breaks.

Tank Mates

Suitable tankmates include other robust Lake Malawi mbuna of similar size and temperament, such as Labeotropheus, Pseudotropheus, and Metriaclima species. Some Synodontis catfish can be housed with mbuna in appropriately large setups. Avoid small, peaceful fish, slow-moving species, long-finned fish, shrimp, and overly passive cichlids—these will be bullied, chased, or eaten. Do not mix with soft-water community fish or South American species, as mbuna require hard, alkaline water. Careful stocking, ample rockwork, and appropriate group sizes (multiple females per male) help reduce aggression and stress.

Breeding

Maylandia zebra is a maternal mouthbrooder, with females incubating eggs and fry in their mouths for approximately three weeks. Males display vibrant coloration and establish territories, courting females through elaborate displays and quivering. After spawning, the female collects the eggs and retreats to a sheltered area, where she fasts during incubation. Fry are released when fully developed and capable of independent feeding. Provide finely crushed spirulina flakes, baby brine shrimp, and microworms. Breeding occurs readily in well-maintained aquariums with stable conditions and appropriate sex ratios. Remove fry or use a separate rearing tank if selective breeding or fry survival is a priority.
