Altolamprologus is a small genus
of pseudocrenilabrine
cichlid
s endemic to Lake Tanganyika
in eastern Africa
. They inhabit areas of the lake with large amounts of rock, most frequently in water two to ten metres in depth. Two formally described species comprise this genus, with perhaps one dwarf A. compressiceps-like species being considered an unedescribed species by some. Neolamprologus fasciatus is also considered by some to belong to this genus.
They are moderately-sized Lamrologines
, growing to a total length of 13-15 cm (c.5-6 inches) in adult males. Their bodies are laterally compressed and remarkably high-backed; hence the scientific name which means "high Lamprologus
" (from Latin
altus, "high"). They are predators which feed on large invertebrate
s and small fish, particularly crustacean

They can be a challenge to breed for the novice. These fish are cave spawners and will spawn under terracotta pot saucers or in large snail
shells. They are a rather slow growing Lamprologine taking approximately two years to reach sexual maturity.

In the aquarium
Altolamprologus are hardy at the standard Lake Tanganyikan water parameters. They are not particularly well-suited for beginners due to their predatory habits however. They can be picky eaters and demand a variety of appropriate living prey to thrive, but they are also prone to gorging themselves if they like the offered food and may become too fat. They also require large tanks – at least one meter/yard in length – to show their natural behavior, and cannot be kept together with small fish or shrimpShrimp
Shrimp are swimming, decapod crustaceans classified in the infraorder Caridea, found widely around the world in both fresh and salt water. Adult shrimp are filter feeding benthic animals living close to the bottom. They can live in schools and can swim rapidly backwards. Shrimp are an important...
