Kribensis Care Guide - Aquarium Setup, Diet & Breeding

Kribensis are small, vividly coloured African cichlids known for their bold personalities and attractive breeding behaviour. Their bodies are usually olive-brown to grey, with a dark lateral stripe, iridescent blue markings and a striking reddish or purple belly, especially in females ready to spawn.

Although modest in size, Kribensis display the confident, territorial character associated with cichlids. They spend much of their time around the lower levels of the aquarium, investigating caves, roots and open patches of substrate. A bonded pair becomes particularly fascinating to watch as they court, defend a spawning site and care for their young.

In nature, these fish live in shaded, slow-flowing waters where submerged roots, leaf litter and rocky crevices provide shelter. Their surroundings can vary from relatively soft, acidic forest streams to more mineral-rich coastal waterways, which helps explain their adaptability in captivity.

Pelvicachromis pulcher has been popular in the aquarium hobby for decades and is often regarded as one of the most approachable African cichlids. Despite their reputation as community fish, they remain territorial around a chosen cave, particularly while breeding.

Kribensis are native to West Africa, particularly southern Nigeria and parts of Cameroon. They inhabit slow-moving rivers, forest streams and lowland waters associated with the Niger Delta and nearby coastal drainage systems.

A pair should have at least 80 litres, with a footprint of around 80 x 30 cm or larger; a bigger aquarium is preferable for a community setup. Use fine sand or smooth gravel so they can sift and move the substrate without injuring their mouths. Include caves, clay pots, coconut shells, rocks, driftwood and dense plants, while leaving open areas for foraging. Arrange decor to break up sight lines and provide separate territories if other bottom-dwelling fish are present.

Males reach up to about 10 cm (4 inches), while females usually grow to around 7 cm (2.8 inches).

Kribensis are omnivores and should receive a varied diet of quality cichlid pellets or granules, supplemented with frozen or live foods such as brine shrimp, daphnia, bloodworm and mosquito larvae. Small portions of spirulina-based foods and occasional blanched vegetables can add useful plant matter. Feed modest amounts that they can consume promptly, as they often forage through the substrate for fallen food.

Kribensis can live with peaceful, similarly sized community fish that occupy the middle and upper levels, including Congo tetras, larger rasboras, peaceful barbs, rainbowfish and robust livebearers. Avoid very timid species, slow-moving long-finned fish and other bottom-dwelling or territorial cichlids, as Kribensis may defend their cave aggressively. During breeding, their territory can expand considerably, so tankmates need plenty of room to retreat.

Kribensis are cave-spawning cichlids that usually breed readily when kept as a compatible pair. Provide a small cave, such as an upturned flowerpot or coconut shell, with a narrow entrance. The female lays her eggs inside while the male guards the surrounding territory. The eggs usually hatch within two to three days, and both parents may protect the free-swimming fry, which can be fed newly hatched brine shrimp or other suitably fine foods.

Females are smaller and usually have a fuller, more rounded body with a prominent red or purple belly, particularly when mature. Males are larger, more elongated and often develop extended points on the dorsal and anal fins, while females generally have shorter, rounder fins.
