Although the island Magdagascar appears geopraphically close to Africa, Malagasy fish are more closely related to the fishes of India, so not really as compatible as the geography suggests.
The plate techtonics reveal that Madagascar more recently broke off from India ibstead of Africa and drifted east.
Some Madagascan species appear to have mirror images in India, and share the same unigue auditory hearing system as species from India.

Not that geography means a lot to most aquarists, but (being a biotope guy), Madagascar and Africa are like world apart as far as cichlids compatabillity goes.
