Kribensis

Pelvicachromis pulcher

Cichlids - African

A vibrant and highly popular dwarf cichlid native to the slow-moving rivers of West Africa. Unlike Rift Lake African cichlids, they prefer soft, slightly acidic water and densely planted tanks. They are generally peaceful in a community tank but become fiercely territorial and aggressive when breeding, often digging pits in the substrate and claiming the bottom zone. They are cave spawners and require hiding spots like driftwood or coconut shells.

Available Varieties

Each variety inherits the species defaults above. Only differences are highlighted.

Unsexed / Juvenile

Typically sold in stores at 3-5cm before sexual characteristics fully develop. At this stage, they are relatively peaceful bottom dwellers that will readily form pairs as they mature.

Same care requirements as the base species

Also known as: Standard, Juvenile Krib

Male

Noticeably larger and more elongated than females, featuring pointed dorsal and anal fins, often with distinct eye-spots (ocelli) on the dorsal fin and tail. Highly territorial when protecting a breeding site.

Differs in 2 traits from base species

Also known as: Male

Adult Size10 cm
TemperamentAggressive

Female

Smaller, stockier, and arguably more colorful than the males. Females develop a brilliant, deep cherry-red or purple belly, especially when conditioning to spawn. They take the lead in initiating courtship.

Kribensis Care Guide Summary

The Kribensis, scientifically known as Pelvicachromis pulcher, belongs to the Cichlids - African family group. Adults reach a maximum size of approximately 10 cm and have a fusiform body shape with a moderate growth rate. Classified as semi-aggressive, this species primarily occupies the bottom and mid-level zones of the aquarium and produces a high level of biological waste.

To thrive, the Kribensis requires a freshwater only aquarium with a minimum volume of 75 litres and a tank length of at least 60 cm. Water temperature should be maintained between 24°C and 28°C, with a pH range of 5.57.5 and a general hardness of 415 dGH. A moderate water flow is preferred. An aquarium test kit can help you monitor these values.

Due to its specialist needs, the Kribensis is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 3 varieties: Unsexed / Juvenile, Male, and Female. Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.

Kribensis Habitat Setup

When setting up an aquarium for the Kribensis, a moderate water flow best suits their natural preferences. Because this species occupies the bottom and mid-level zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour, driftwood, which can serve as both a hiding place and a dietary supplement, shells for breeding and shelter, and dense planting to provide cover, break sightlines, and reduce stress. Keepers should note that expect substrate disturbance, so lightweight décor should be secured. Browse aquarium sand substrate options to find the best fit.

Kribensis Compatibility Notes

Classified as semi-aggressive, the Kribensis is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, ornamental shrimp are not safe companions, conspecific aggression can be intense, especially in smaller tanks, and territorial behaviour may cause issues if hiding spots or floor space are limited. Selecting tankmates that favour different water layers from the bottom and mid-level zones can help reduce competition and territorial overlap.

Kribensis Feeding & Diet Considerations

The Kribensis will hunt and eat ornamental shrimp, making it unsuitable for shrimp-focused setups and will eat fry, so breeding efforts in the same tank are unlikely to succeed. Find quality Kribensis fish food for this species.

A strikingly colorful dwarf cichlid native to the Orinoco River basin. Famous for its vibrant blue spangles and peaceful demeanor compared to larger cichlids. They are strictly thermophilic (require high temperatures of 27-30°C / 81-86°F) and thrive in soft, acidic water. As 'earth-eaters' (Mikrogeophagus), they sift sand for food and form monogamous pairs.

Bolivian Ram

Mikrogeophagus altispinosus

Cichlids - South American
8 cm Mostly Peaceful

A hardy and relatively peaceful dwarf cichlid native to the Amazon river basin. Compared to the popular German Blue Ram, the Bolivian Ram is larger, much more forgiving of water parameters, and prefers slightly cooler temperatures. They are eartheaters (geophagine) that sift through the substrate for food, making soft sand an absolute requirement to prevent gill damage.

A stunning South American dwarf cichlid known for its distinct spade-shaped tail and brilliant color morphs. They are bottom-dwelling micro-predators that sift sand for food. While generally peaceful in community tanks, they are highly territorial when breeding. They thrive in soft, acidic blackwater conditions.

African Jewel Cichlid

Hemichromis bimaculatus

Cichlids - African
14 cm Aggressive

A strikingly beautiful but notoriously aggressive West African riverine cichlid. Unlike the alkaline-loving Rift Lake cichlids (e.g., Mbuna), Jewel Cichlids prefer neutral, softer water parameters. They are renowned for their brilliant red breeding dress and iridescent blue spots, but also for their extreme territoriality, especially when forming pairs and spawning. They are avid diggers and will uproot most plants.
