Lake Managua

Lake Managua (Xolotlán), ~1,040 km² in the Nicaraguan depression, draining south to Lake Nicaragua via the Río Tipitapa. Shallow and, today, heavily impacted by the city on its shore, it still carries a Central-American cichlid assemblage — Amphilophus, Parachromis and relatives — and is ringed by volcanic crater lakes that hold their own endemic fishes (Bussing 1998).

A shoreline of separate worlds

Lake Managua does not have one habitat but a mosaic of them, and the boundaries are sharp. A cichlid adapted to grazing algae off boulders may never cross the few metres of open sand to the next reef — which is exactly why so many species here live nowhere else on Earth.
