Common name:
Scientific name:Altolamprologus calvus
Synonyms:(none)
Size:Up to 6" (15cm), female smaller - 4" (10cm).
Origin:Lake Tanganyika, E.Africa
Tank setup:Piles of rocks, with sand or fine gravel substrate. Shells can also be added.
Compatibility:Not for the community tank, keep with similar sized Tanganyikan cichlids, which are not overly aggressive, such as Julidochromis or larger shell dwellers.
Temperature:24-27oC (75-81oF)
Water chemistry:Hard and alkaline: pH 7.8-9.0, GH 12-20, KH 14-20
Feeding:Will take most aquarium foods, but frozen or live foods are preferred, such as bloodworm and brine shrimp (Artemia).
Sexing:Males are usually significantly larger in established pairs. Mature males will also appear deeper bodied with more elongated finnage. These differences are not apparent in juveniles.
Breeding:Substrate spawner, the female will usually select a cave with a very narrow entrance, which the male cannot enter. The male will guard the surrounding territory. The female will guard the eggs and fry until they are free swimming.
Comments: A. calvus is a slow-growing cichlid, but becomes a truly stunning fish and a superb addition to a Tanganyikan setup. There are a number of colour variants, such as the 'white' calvus and the stunning 'black' form. Altolamprologus may eat very small fishes and fry, but are not generally a danger to adult Tanganyikan cichlids. They should not be kept with boisterous fishes such as Tropheus and the Malawi mbuna.
