Overview

Kribensis (Pelvicachromis pulcher), also known simply as "Kribs," are colorful and peaceful dwarf cichlids originating from the rivers of West Central Africa. Their vibrant hues and manageable size make them a popular choice for both beginner and experienced aquarists. Known for their fascinating breeding behavior and strong parental instincts, Kribensis can thrive in a well-maintained community tank.

Origin and Natural Habitat

Kribensis are native to the slow-moving rivers and streams of West Central Africa, particularly in Nigeria and Cameroon. They inhabit areas with dense vegetation and soft, slightly acidic water.

Appearance and Size

Kribensis are known for their striking coloration. Females display a prominent purple or reddish abdomen, especially when ready to breed, while males are generally slimmer, larger, and less colorful but have longer dorsal and anal fins. In aquariums, they typically grow to about 8 - 10 cm (3.15 - 3.94 inches).

Tank Requirements

• Tank Size: A minimum of 75 liters (20 gallons) is recommended, especially if housing a pair or a small group.
• Water Parameters:
• pH: 5.0 - 7.5
• Water Hardness: 0 - 12°N (0 - 214 ppm)
• Temperature: 24 - 29°C (75.2 - 84.2°F)
• Tank Setup: Provide plenty of hiding spots using rocks, driftwood, and plants. Subdued lighting and a soft substrate will mimic their natural habitat. Include caves or structures like coconut shells or ceramic flower pots to encourage spawning.

Temperament and Tank Mates

Kribensis are generally peaceful and suitable for community tanks, but they can become territorial during spawning. They coexist well with other peaceful species such as tetras, rasboras, Corydoras catfish, and other non-aggressive dwarf cichlids. Avoid housing them with overly aggressive fish or fin-nippers.

While they can be kept as a pair or in a small group, ensure enough space and hiding spots to prevent territorial disputes, especially among males.

Feeding and Diet

Kribensis are omnivorous and thrive on a varied diet:

• High-quality sinking pellet food suitable for cichlids
• Live and frozen foods such as bloodworms, brine shrimp, and daphnia to enhance color and vitality
• Occasional vegetable matter like blanched spinach or spirulina-based foods

Breeding

Kribensis are among the easiest cichlids to breed in captivity. If provided with suitable conditions, it's common to find them spawning in the aquarium:

• Introduce a cave or hiding spot like an empty coconut shell or ceramic pot to encourage spawning.
• The female will display her vibrant purple abdomen to attract the male.
• After spawning, the female guards the eggs, while both parents fiercely protect the fry.
• Parents will take the fry on "tours" around the aquarium, demonstrating their devoted parenting behavior.

Lifespan

With proper care, Kribensis can live up to 5 years in captivity.

Conclusion

Kribensis (Pelvicachromis pulcher) are a colorful and engaging addition to any freshwater aquarium. Their peaceful nature, ease of care, and fascinating breeding behavior make them a favorite among aquarists. With the right environment and diet, these dwarf cichlids will thrive, offering both beauty and dynamic interaction in your tank.
