About the species

Reganochromis calliurus is a slender, silvery cichlid endemic to Lake Tanganyika, the sole member of its genus and one of the lake's understated sand- and mud-dwellers. It makes a living patrolling the gently sloping sediment of deeper coastal waters, hunting shrimp and other invertebrates well below the depths most aquarium-trade Tanganyikans inhabit. Its most surprising trait is its breeding strategy: it is a biparental mouthbrooder, with male and female taking turns carrying the eggs and fry inside their mouths, swapping the brood back and forth in a quiet rocky cave.
