Pelvicachromis pulcher (Kribensis) is one of the most colourful and manageable freshwater dwarf cichlids popular with fishkeepers worldwide. This guide covers everything you need to know about their care, natural habitat, breeding, and tank compatibility.
If I had to recommend one fish for both beginners and experienced aquarists, it would be the Kribs cichlid. Their friendly personality, compact size, and vibrant colours make them a joy to keep. Kribensis recognise their owners, usually as a food source, and exhibit far more intelligence than typical aquarium fish.
Their coloration is truly striking: a creamy white body marked by a bold black horizontal stripe, a deep red or purple belly especially vivid in breeding females, and flashes of iridescent blue on their pelvic fins. Additionally, healthy fish show green or blue cheek tints. When stressed, such as in fish stores, their colours are subdued but return quickly in a calm aquarium.
Kribs originate from southern Nigeria and coastal Cameroon, typically inhabiting calm or slow-moving waters rich with dense vegetation. Natural water tends to be warm (24–26°C), soft, and acidic with pH around 5.6 to 6.2. Mimicking this environment is key to their wellbeing.
A 100-litre aquarium is ideal for a pair, as they establish territories. They thrive in soft, slightly acidic water, but accept a range of parameters. A sandy substrate encourages natural digging and cave building behaviours.
Your tank should contain several caves or hollow structures to serve as safe retreats. Bogwood is a great addition, as it releases tannins that mildly tint the water, have antiseptic properties, and create a natural aesthetic. Plants are welcomed but be aware Kribensis may uproot them while digging; positioning plants around the edges helps.
Omnivorous and bottom-oriented, Kribs consume high-quality cichlid pellets as a dietary staple, supplemented a couple of times weekly with live or frozen foods such as brine shrimp or bloodworms. Target feeding may be necessary to ensure they receive adequate nutrition, especially if housed with larger, more aggressive feeders.
The easiest way to form a pair is start with 6 or more juveniles and allow pairs to form naturally. Alternatively, select a male (larger, pointed fins) and a brightly coloured female from a shop. Wild-caught pairs tend to show more reliable breeding and parenting behaviours.
Set up a tank with caves and maintain stable water conditions: 24-26°C, slightly acidic pH (5.6-6.2), with soft water. Provide lots of hiding spaces and keep tankmates peaceful or breed them separately.
Kribs are cave spawners; females lay eggs on the roof of a chosen cave. The male fertilises the eggs and defends the territory, while the female guards the eggs inside the cave. Monitor for aggression; some farm-raised fish females may attack males during breeding, so provide ample cover for escape.
After hatching, fry typically stay close to the mother, recognizable by her distinctive purple belly. Feed newly hatched brine shrimp and, after a few weeks, crushed high-quality flake food to encourage growth. Introduce the fry to a varied diet to support healthy development.
Because their natural habitat is similar to South American species, Kribensis can live alongside a variety of peaceful fish. Scholarly dither fish like tetras help keep them visible as they feel more secure. Bottom dwellers that might eat eggs should be avoided in breeding setups, but in community tanks, as long as the tank isn't overstocked, Kribs coexist well with most small to medium peaceful fish.
The Kribensis is a splendid, colourful freshwater fish that's rewarding to keep and breed. Ensuring compatible water parameters, a rich environment with hiding spaces, and a nutritious diet will keep your Kribs thriving. When selecting fish, opt for responsible sources to support ethical breeding and avoid releasing aquarium fish into the wild to protect ecosystems.
