Pelvicachromis

The yellow kribensis, Pelvicachromis humilis, is a cichlid from Sierra Leone, Liberia and Guinea, and the largest known species in its genus. Rare in the hobby, it is seen in several morphs including 'Guinea' and 'Liberia red', some of which may eventually be described as distinct species. It is more elongate than its relatives, with a comparatively long snout, and is aggressive towards conspecifics, so only a single pair should be kept unless the tank is very large.

The kribensis, Pelvicachromis pulcher, is a cichlid from Nigeria and Cameroon, found in still and slow-moving, heavily vegetated waters. One of the most common cichlids in the hobby since the 1950s, it is almost always captive bred, and farmed fish are far more adaptable to water chemistry than wild ones. A cave spawner that forms monogamous pairs, it is often the first fish bred by newcomers and becomes very territorial when breeding.

The ocellated kribensis, Pelvicachromis subocellatus, is a cichlid from Nigeria, Gabon and the Democratic Republic of Congo. It inhabits pools and slow-moving streams in coastal areas, some of them brackish. Less commonly seen than other Pelvicachromis, it is available in morphs such as 'Matadi' and 'Moanda', and has a higher, shorter body than its congeners with much lighter spotting in the upper part of the caudal fin.

The striped kribensis, Pelvicachromis taeniatus, is a cichlid from still and slow-moving forest streams and rivers in Nigeria and Cameroon. Over a dozen morphs are available, including 'Dehane', 'Moliwe', 'Lobe' and 'Nigeria Red', and these should not be cross bred if the lines are to stay pure. A more pronounced upper lip, often bright yellow, separates it from congeners, and unlike most Pelvicachromis the males rival the females in colour.
