About the species

Maylandia cyneusmarginata is a narrowly distributed mbuna cichlid endemic to a short stretch of the Malawian western shoreline of Lake Malawi. Known from only three sites — Nkhotakota, Nkhomo Reef, and Chidunga Rocks — it is one of the lake's most range-restricted members of the Pseudotropheus zebra complex, and its Near Threatened IUCN status reflects just how exposed such a small-footprint species is to sedimentation and collection pressure. The name refers to the blue marginal band on the dorsal fin that distinguishes it from most congeners at a glance.
