Care
The Tanganyikan Killifish is endemic to Lake Tanganyika, where it is most commonly found amongst the rocky habitats close to shore, and occasionally out in open water. This is a large, active, non-annual killifish that requires a spacious and mature aquarium. Hard, alkaline water is absolutely essential. The best choice of substrate would be either coral sand or aragonite which will help to keep the water hard and alkaline. Outcrops of rocks (ocean rock or tufa rock is ideal) can be assembled here and there, but remember to leave enough open swimming space along the front of the aquarium. Filtration should be efficient with moderate water movement and a good level of oxygenation. Frequent partial water changes are a must in order to keep nitrate to a minimum, as these fish are very sensitive to deteriorating conditions. When doing so, be very careful to match up the temperature, hardness, and pH of the new water to that of the existing tank water. Tanganyikan Killifish are best maintained in good sized groups, with at least 2 females to every male. Juveniles may be relatively drab in appearance, but the adults - particularly males in breeding condition - are absolutely dazzling. Although their native waters are full of cichlids, this is not always a good mix in the confines of the home aquarium. Only in very roomy quarters should you consider adding some of the more placid Tanganyikan species such as Cyprichromis or Paracyprichromis. Tanganyikan Killifish can be very delicate and should be acclimatised to the aquarium very carefully.
Feeding
These fish seem to prefer small frozen foods such as vitamin-enriched brineshrimp, bloodworm, white mosquito larvae, and Mysis shrimp. Over time, some aquarists find that their fish will also take dried foods.
Breeding
This species has been bred in the home aquarium. Following an elaborate courtship ritual in which the male entices the female to spawn, eggs are deposited in rocky crevices. The adult fish will predate on the eggs so will need moving to another aquarium.
