Maylandia

Genus Overview: Maylandia (Zebra Mbuna)

The genus Maylandia represents one of the most foundational, diverse, and dominant forces within the rock-dwelling Mbuna complex of Lake Malawi. Highly celebrated for their bold vertical striping and explosive territorial personalities, these heavy-set cichlids are the architectural anchors of shallow rocky reefs across the entire lake ecosystem.

The Great Synonym Debate & Scraping Mechanics

For decades, this group sat at the heart of one of the most famous debates in cichlid taxonomy. While many hobbyists and commercial importers became accustomed to the name Metriaclima (established in 1997), global scientific catalogs and ichthyological databases firmly recognize Maylandia as the senior valid name.

Anatomically, they possess broad, blunt heads with straight, wide jaws lined with thousands of microscopic bicuspid teeth. In their natural wild biotope, they are obligate herbivores that graze heavily on the sunlit upper rock tiers. They swim up to a boulder, align their mouths firmly against the stone, and violently close their jaws while pulling backward—combing out massive quantities of loose algae, diatoms, and tiny invertebrates trapped in the rocky carpets.

Valid Species Directory

With massive evolutionary radiation, there are currently over 35 scientifically validated species and hundreds of distinct geographic island variations:

• Maylandia aurora (Burgess, 1976) – The Aurora Mbuna, noted for its bright yellow chin and throat.
• Maylandia barlowi (Mckaye & Stauffer, 1986)
• Maylandia callainos (Stauffer & Hert, 1992) – The classic Cobalt Blue Zebra.
• Maylandia chrysomallos (Stauffer, 1997)
• Maylandia emmiltos (Stauffer, 1997) – The Red-top Zebra cichlid.
• Maylandia estherae (Konings, 1995) – The world-famous Red Zebra.
• Maylandia flavifemina (Konings & Stauffer, 2006)
• Maylandia greshakei (Meyer & Foerster, 1984) – The Ice Blue / William's Mbuna.
• Maylandia hajomaylandi (Meyer & Schartl, 1984)
• Maylandia lombardoi (Burgess, 1977) – The Kenyi Mbuna, famous for reversed dimorphism; females are striped blue, while males turn vibrant yellow.
• Maylandia mbenjii (Stauffer, 1997)
• Maylandia phaeos (Stauffer, 1997)
• Maylandia pyrsonotos (Stauffer, 1997)
• Maylandia sandaracinos (Stauffer, 1997)
• Maylandia zebra (Boulenger, 1899) – The absolute type species of the genus.

This genus displays profound polymorphism. Populations naturally throw diverse mutations, ranging from classic dark-barred "BB" phases to solid pinkish-orange "O" phases and highly prized, black-blotched "OB" configurations.

Aquarium Husbandry

Adult lengths run from 4.5 to 6 inches (11–15 cm). Because males are hyper-dominant and display extreme aggression toward conspecifics (similar-looking species), they demand spacious aquariums measuring at least 4 to 5 feet long (75 to 125 gallons).

An absolute abundance of heavy rockwork forming structural cave matrices is vital to block lines of sight and manage aggression. Because they are obligate herbivores, they require a strict, high-fiber vegetarian diet rich in spirulina. Heavy-protein or mammalian fats will break down their lengthy digestive tracts, triggering fatal swellings known as "Malawi Bloat".
