Zebra Mbuna

Maylandia zebra comes from the rocky shorelines of Lake Malawi in East Africa, one of the oldest and deepest lakes in the world. In the wild, they live in the surge-battered shallows, picking algae off rock faces. Males flash brilliant blue with bold vertical black bars, while females and juveniles typically show a more muted brownish or tan coloration, though some populations throw out orange-blotched females that are genuinely striking in their own right.

These are hard-water fish through and through. They want a pH north of 7.8, good mineral content, and temperatures in the mid-to-upper 20s Celsius. Crushed coral or aragonite substrate goes a long way toward keeping the buffering capacity where it needs to be, and heavy rockwork isn't just decorative but essential for breaking up lines of sight. Without plenty of caves and visual barriers, males will harass subordinates relentlessly.

Diet is mostly herbivorous. Spirulina-based flakes and pellets form the backbone of what they should be eating, supplemented with blanched vegetables occasionally. Avoid high-protein meaty foods, as a diet too rich in animal protein is linked to a condition called Malawi bloat, which can be fatal if not caught early. This is one of the most common mistakes new mbuna keepers make.

For temperament, expect real aggression. This is not a fish that settles down with age. Males claim territories and defend them hard, and they'll test every tankmate regularly. Kept right, though, there's nothing quite like a full mbuna display tank in full swing.
