Rainbow Kribs are the golden child of the Cichlid species. Where some Cichlids become giants, others inhabit high levels of undesirable rage. And, water conditions are never the same. In these regards, Rainbow Kribs are near perfect.
As omnivores, Kribs will accept a range of foods including, flake and pellet foods. Also feed them live or frozen brine shrimps and bloodworms. Though Kribs are good in a community tank, take care in choosing their neighbours. They are likely to nip the fins of slow-moving fish, like freshwater Angelfish. If you want other Cichlids species in your tank, try to pick ones who are not bottom dwellers. Kribs are also territorial of any caves you may have in your aquarium. They will need to be the only ones who enjoy this feature—even between Kribs.
Kribs will prefer shallow water populated with live vegetation. They are unlikely to destroy any vegetation. When it comes to caves, unless you are attempting to breed Kribs, they will need one or even two for themselves. One entrance will minimise light. Make sure the stones used in any caves are also smooth.
Females have shorter, rounded fins with a broad yellow across the top dorsal fin. Their bodies are smaller than males. During the breeding season, the female will display brilliant cherry-red colours on her belly. Males are longer bodies and have thinner fins. Unlike other species of fish, the males' colours are duller than the females. Rainbow Kribs are easy to mate. Once you have a pair, do not introduce any new fish. Males will become aggressive, and females will even quarrel with one another. Offer caves in the breeding tank for the pair and let them choose the best place for their young. Fry will need to stay with their parents as they mature. Both
parents will tend to the care of their fry. If one becomes more involved than the other, the attentive parent may become hostile and attack the other.
