Kribensis
Also known as: Pelvicachromis pulcher
Pelvicachromis pulcher, commonly known as the Kribensis, is a small, colorful West African cichlid prized for its vibrant appearance and relatively peaceful nature. The Kribensis originates from West Africa, specifically Nigeria and Cameroon, inhabiting slow-moving rivers, streams, and floodplain pools with dense vegetation and sandy substrates., reaches Adult size: 8-10 cm in captivity, typically lives 5-8 years under optimal aquarium conditions., and is kept at 24-28°C (75-82°F); stable temperatures within this range are critical for health and breeding behavior.. Individual fish vary, so treat this as a general guide rather than a guarantee.
Key facts
- Lifespan: 5-8 years under optimal aquarium conditions.
- Adult size: Adult size: 8-10 cm (3-4 inches); males typically reach 10 cm, females slightly smaller at 8 cm.
- Temperament: Generally peaceful and territorial, especially during breeding; can be mildly aggressive toward conspecifics or similar-sized fish but rarely hostile toward dissimilar species.
- Minimum tank: Minimum 75 liters (20 gallons) for a pair; 115 liters (30 gallons) recommended for a group or community setup.
- Water temperature: 24-28°C (75-82°F); stable temperatures within this range are critical for health and breeding behavior.
- pH range: 6.0-7.5 pH; prefers slightly acidic to neutral water, tolerating mild fluctuations but thriving in stable conditions.

About the Kribensis
Pelvicachromis pulcher, commonly known as the Kribensis, is a small, colorful West African cichlid prized for its vibrant appearance and relatively peaceful nature. Males display elongated fins and iridescent blue-green bodies with red bellies, while females are smaller with a distinctive pinkish-red belly and rounded fins. They are substrate spawners, often laying eggs in caves or crevices, and exhibit strong parental care. In the wild, they forage along the bottom for small invertebrates and organic detritus.
Lifespan and health
With proper care, Kribs typically live 5-8 years, though exceptional specimens may reach 10 years in pristine conditions; longevity is strongly tied to stable water parameters, low stress, and a varied diet. Breeding can shorten lifespan slightly due to the energetic cost of parental care, so limiting breeding attempts to once every few months helps preserve health. Common health issues include ich (white spot disease) triggered by temperature fluctuations or poor water quality, treatable with gradual temperature increase to 29°C (84°F) and aquarium salt; bacterial infections such as fin rot often result from injury or degraded water, requiring immediate water improvement and antibacterial treatment; intestinal parasites may occur from live food sources, preventable by quarantining live feeds and using high-quality frozen alternatives. Regular observation for lethargy, clamped fins, or loss of appetite is essential for early intervention.

Care and tank setup
Tank setup should include a sandy or fine gravel substrate to mimic their natural habitat, along with plenty of hiding places such as driftwood, rock caves, and dense planting (e.g., Anubias, Java fern) to reduce stress and encourage natural behavior. Provide at least one cave per fish for territorial security, especially if keeping multiple individuals. Water conditions must be maintained with weekly 25% water changes to keep nitrates below 20 ppm; use a gentle filter to avoid strong currents, as they prefer calm waters. Feeding should occur 2-3 times daily in small amounts they can consume within 2-3 minutes; vary diet with protein-rich foods 4-5 times weekly and vegetable matter 2-3 times weekly to support health and coloration. Suitable tankmates include peaceful, similarly sized species such as tetras, rasboras, Corydoras catfish, and small gouramis; avoid aggressive cichlids, large predators, or fin-nippers like tiger barbs.
