Altolamprologus calvus
Altolamprologus calvus is a cichlid endemic to the southern shoreline of Lake Tanganyika in eastern Africa. The species has an extremely laterally compressed body and a high dorsal fin. Males may grow to 13 cm, while females are normally smaller.
It is physically similar to its close relative A. compressiceps, though it is less deep-bodied and has a longer snout.
A. calvus is commonly kept as an aquarium fish in setups devoted to East African fish. Several local variants exist. Examples include:
- 'Black Sambia'
- 'Black Pectoral'
- 'Black Zaire'
- 'Black Kapampa'
- 'Yellow'
- 'White'
