Altolamprologus Calvus 'Congo Black' (Wild)
Common name: Congo black calvus
Scientific name: Altolamprologus calvus
Distribution: Lake Tanganyika
Habitat: Jumbled, rocky shores
Temperature: 76 – 80°F
pH: 7.5 – 9.0
Adult size: 4 inches (females), 6 inches (males)
Sexing: Males reach a larger adult size than females
Diet: Enjoys frozen and live foods but will usually take dried foods.
Conspecifics: Does will in pairs or larger groups.
Tankmates: Similarly-sized cichlids or other fish with the same water chemistry requirements, very suitable for a Tanganyikan biotope. Avoid very aggressive tankmates (such as mbunas) and tankmates small enough to be eaten (such as small shelldwellers).
Notes: Altolamprologus calvus is a very slow grower that can take more than 2 years to reach sexual maturity. This species can be distinguished from the very similar A. compressiceps by a lack of scales on its head and a shallower body. It is recommended to keep Altolamprologus calvus over a dark substrate, as a light substrate tends to wash out their stunningly contrasting scales.
