Behaviour & Temperament

African Jewel Cichlid is a semi-aggressive species (8/10), while Peacock Cichlid (Aulonocara) is moderately assertive (6/10). This modest difference means African Jewel Cichlid may occasionally assert dominance over Peacock Cichlid (Aulonocara).

African Jewel Cichlid and Peacock Cichlid (Aulonocara) both frequent the Middle (Open Water) and Bottom (Substrate) 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 African Jewel Cichlid (6.5–7.5) 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 African Jewel Cichlid 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), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding). 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 African Jewel Cichlid 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 African Jewel Cichlid 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 African Jewel Cichlid 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 African Jewel Cichlid or Peacock Cichlid (Aulonocara) aggressive?

African Jewel Cichlid is semi-aggressive (8/10) and Peacock Cichlid (Aulonocara) is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do African Jewel Cichlid and Peacock Cichlid (Aulonocara) need?

Their pH requirements do not overlap. African Jewel Cichlid prefers 6.5–7.5, while Peacock Cichlid (Aulonocara) needs 7.8–8.6. This makes them incompatible in the same water chemistry.

How do I manage African Jewel Cichlid's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives African Jewel Cichlid 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.
