The Mdoka population

Protomelas insignis "Mdoka" is the Mdoka population of Protomelas insignis, a geographic colour form from the Malawi coast of Lake Malawi in the far northern part of the lake. It is the same species as Protomelas insignis, distinguished by its collection locality and local coloration; aquarists keep and breed it as a discrete, provenance-labelled line.

About the species

Protomelas insignis is a mid-sized haplochromine cichlid endemic to Lake Malawi with a behavioral habit that sets it apart from nearly every other hap in the lake: it makes its living stealing eggs. Rather than grazing algae or sifting sand, it cruises above rocky breeding arenas, watching the spawning activity of other cichlids, and darts in at precisely the right moment to snatch freshly laid eggs before the mouthbrooding female can collect them. This specialization has shaped everything about the fish — its body plan, its hunting patience, and its comparative rarity across a lake that holds hundreds of other cichlid species.
