About the species
Altolamprologus calvus — the pearly or black calvus — is a slender, armor-scaled predatory cichlid found only along the rocky southwestern shore of Lake Tanganyika. Its body is so strongly flattened from side to side that it can slip into rock cracks too narrow for almost any rival or predator — a build that doubles as a hunting tool and as the basis of an unusual breeding trick, in which the female spawns inside a crevice too small for the male to follow. Patient, deliberate, and slow-growing, it ranks among the lake's most coveted aquarium fish, and its fortunes are now tied to the silting of the very shoreline it depends on.
