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 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. To replicate their natural habitat, the tank should include sand (sifters), driftwood (digestion/hiding), shells (breeding/hiding), and plants - densely covered.

Kribensis can be kept singly or in a group, making them flexible additions to most setups. Keepers should be aware that this species is not safe with ornamental shrimp, can be aggressive toward its own kind, and will defend a territory within the tank. 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.

7.5 cm Mostly Peaceful

A peaceful, colorful dwarf cichlid from West Africa. Unlike many cichlids, it is plant-safe and generally suitable for community tanks. It is famous in the hobby as an efficient biological control for pest snails.

German Blue Ram

Mikrogeophagus ramirezi

Cichlids - South American
6 cm Mostly Peaceful

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.

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.

Dwarf Gourami

Trichogaster lalius

Anabantoids
7.5 cm Semi-Aggressive

A peaceful to semi-aggressive labyrinth fish native to South Asia. Famous for their brilliant metallic blue and red stripes. While generally suitable for community tanks, males are territorial toward each other and similar-looking fish. They are sensitive to water quality and prone to Iridovirus if stressed. Requires access to the surface to breathe.

Texas Cichlid

Herichthys cyanoguttatus

Cichlids - Central American
30 cm Aggressive

The Texas Cichlid is the only cichlid species native to the United States. Known for their striking pearlescent blue/green spots and extreme territorial behavior, they require large tanks and robust filtration. They are notorious for rearranging aquariums, digging massive pits, and destroying live plants.

Yellow Lab (Mbuna)

Labidochromis caeruleus

Cichlids - African
10 cm Semi-Aggressive

The Electric Yellow Lab is one of the most popular and widely kept African Cichlids from Lake Malawi. Classified as an Mbuna (rock-dwelling cichlid), they are famous for their vibrant yellow coloration and striking black dorsal stripes. While considered one of the most 'peaceful' Mbuna, they are still highly territorial cichlids that require hard, alkaline water, a sandy substrate for digging, and abundant rockwork to establish territories.
