Special RequirementsTanganyikan cichlid tank only.

Paracyprichromis nigripinnis are best maintained in large mixed-sex groups in a deep, spacious Tanganyikan themed aquarium. The tank should include plenty of rockwork, and this should be split into arrangements of sheer walls (ensure that such structures are very secure) and shady caves. These fish will spend a lot of their time hanging against these rocky walls, and the males will defend their chosen caves. Paracyprichromis nigripinnis are relatively peaceful and are best kept either in a species-only tank, or else with other Tanganyikan cichlids of a similar size and disposition, and with similar dietary needs. Some of the Cyprichromis species make good companions as they tend to occupy a different area of the aquarium, staying further out in mid-water. It is best to keep a group of at least 8 Paracyprichromis nigripinnis, with one male and several females. If two males are kept in the confines of the same tank, they are likely to argue. Hence we would recommend that either one male is kept, or several. This will help to spread out any possible aggression. Wherever possible, outnumber each male with 3 or more females. This does mean that if you plan on keeping more than one male, you will require a more spacious aquarium to accommodate the larger group which will consist largely of females. These fish are easily stressed, so care should be taken when catching, transporting, and acclimatising them to a new aquarium. Excellent water conditions must be maintained at all times, with plenty of frequent partial water changes to keep nitrates at a minimum. Add new (dechlorinated) water slowly and ensure it is of a similar temperature to that of the tank water. A large breeding colony of Paracyprichromis nigripinnis really makes for a spectacular display, and their colours are best shown off under subdued lighting. A rare albino variety is sometimes available.

These fish spawn in an upside down position near upright slates/vertical rock faces. The female mouthbroods the eggs. When the fry are released, they will be at risk in a Tanganyikan community tank. They will stand a much better chance in a species-only aquarium that has some fine-leaved plants such as Ceratophyllum demersum for the fry to hide amongst. There are actually many reports of older members of the colony looking after the young, even if they are not the parents.
