The compressed cichlid, Altolamprologus compressiceps, is a substrate-spawning cichlid endemic to Lake Tanganyika, where it lives among rocky rubble. Its colour pattern varies with locality, and many forms are traded under their own names, such as 'Burundi red fin' and 'black cheek'. Populations should be kept apart and labelled with their collection locality to avoid hybridisation. A smaller, shell-dwelling fish traded as A. sp. compressiceps 'shell' appears to be an undescribed species.

The humphead cichlid, Cyphotilapia frontosa, is a large cichlid endemic to the northern portion of Lake Tanganyika. Known in the hobby as 'frontosa' or 'front', it grows to 255 mm SL and is gregarious, forming a dominance hierarchy in groups of at least five. Populations are usually labelled by locality to preserve pure bloodlines, and forms referred to as 'Blue Zaire' belong to its only congener, C. gibberosa.
