Description
Cross River Kribensis (Pelvicachromis pulcher “Cross River”) is a distinct and highly prized variant of the popular Kribensis cichlid, native to the Cross River basin in Nigeria and Cameroon. While closely related to the regular Kribensis (Pelvicachromis pulcher), the Cross River variant exhibits several notable differences in coloration, size, and behaviour, making it a sought-after species for aquarists interested in more vibrant and region-specific African cichlids. It is known for its striking red, purple, and gold hues, particularly pronounced in males, and a more elongated body shape compared to the typical West African Kribensis.
Features of Cross River Kribensis
-
Slightly larger than regular Kribensis, reaching 12–13 cm in length
-
More intense coloration: males display deep reds, purples, and golds, females have vibrant belly colours
-
Elongated and streamlined body shape compared to the stockier regular Kribensis
-
Similar peaceful temperament but with slightly more territorial tendencies during breeding
-
Exhibits complex courtship and parental care, with both parents guarding the fry
Differences from Regular Kribensis
-
Cross River Kribensis has richer and more vivid coloration, especially in breeding males
-
Body shape is more elongated and less robust than regular Kribensis
-
Originates specifically from the Cross River drainage, whereas regular Kribensis populations are more widespread across West Africa
-
Cross River variant often demands slightly higher water quality and stable conditions
The best aquarium size for Cross River Kribensis
A minimum tank size of 80 litres is recommended for a pair. For a community or breeding setup, a 120-litre aquarium or larger is preferable to provide adequate territory and reduce aggression during spawning.
Tank Mate Compatibility for Cross River Kribensis

Diet for Cross River Kribensis
Omnivorous with a preference for protein-rich foods. Feed a varied diet consisting of high-quality cichlid pellets, frozen bloodworms, brine shrimp, and occasional vegetable matter such as blanched spinach or spirulina flakes. Multiple small feedings daily encourage optimal growth and vibrant colouration.
Aquarium Setup Cross River Kribensis
Aquarium Filtration
Moderate to strong filtration is necessary to maintain clean, well-oxygenated water. Canister filters or high-quality internal filters work well, combined with regular water changes.
Aquarium Plants
Dense planting with species such as Vallisneria, Anubias, and Java Fern provides cover and helps define territories. Floating plants can reduce light intensity, creating a more natural environment.
Aquarium Lighting
Moderate lighting supports plant growth without stressing the fish. Avoid overly bright conditions to maintain natural behaviour.
Aquarium Heating
Maintain temperatures between 24–27°C with a reliable heater. Stability is key to prevent stress and encourage breeding.
Aquarium Substrate
Use fine gravel or sand substrate, allowing natural digging and foraging behaviours.
Aquarium Decorations
Provide plenty of caves, rocks, and driftwood to establish territories and breeding sites. Open swimming areas should be maintained to allow natural movement and social interactions.
