Can Kribensis and Peacock Cichlid (Aulonocara) Live Together?

🔴Not Recommended

Kribensis and Peacock Cichlid (Aulonocara) are not recommended as tank mates due to conflicting pH requirements. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Behaviour & Temperament

Both Kribensis and Peacock Cichlid (Aulonocara) are moderately assertive species with an aggression score of 6/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.

Kribensis and Peacock Cichlid (Aulonocara) both frequent the Bottom (Substrate) and Middle (Open Water) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

Additional behavioural considerations to keep in mind: Two territorial species may clash over territory, especially in smaller tanks.

Water Parameters

The safe temperature window for both species falls between 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

The pH requirements of Kribensis (5.5–7.5) and Peacock Cichlid (Aulonocara) (7.8–8.6) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.

Tank Setup

To house Kribensis and Peacock Cichlid (Aulonocara) together, plan for an aquarium of at least 240 litres with a minimum length of 120 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

Providing a mix of open swimming space and sheltered areas with rocks, driftwood, or plants will keep both species comfortable and allow natural behaviour.

Specific environmental needs for this combination include: Sand (Sifters), Driftwood (Digestion/Hiding), Shells (Breeding/Hiding), Plants - Densely covered, Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.

Frequently Asked Questions

Can Kribensis and Peacock Cichlid (Aulonocara) live together?

No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.

What size tank do Kribensis and Peacock Cichlid (Aulonocara) need?

A minimum of 240 litres (tank length at least 120 cm) is recommended. This provides enough space for both species to establish their own areas and reduces the likelihood of territorial disputes.

What water temperature is best for Kribensis and Peacock Cichlid (Aulonocara) together?

Keep the aquarium between 24°C and 28°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.

Are Kribensis or Peacock Cichlid (Aulonocara) aggressive?

Kribensis is moderately assertive (6/10) and Peacock Cichlid (Aulonocara) is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Kribensis and Peacock Cichlid (Aulonocara) need?

Their pH requirements do not overlap. Kribensis prefers 5.5–7.5, while Peacock Cichlid (Aulonocara) needs 7.8–8.6. This makes them incompatible in the same water chemistry.

How do I manage Kribensis's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Kribensis space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
