Can Peacock Cichlid (Aulonocara) and Uaru Live Together?

Peacock Cichlid (Aulonocara) is a moderately assertive species (6/10), while Uaru is generally mild-mannered (4/10). This modest difference means Peacock Cichlid (Aulonocara) may occasionally assert dominance over Uaru.

Peacock Cichlid (Aulonocara) and Uaru 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.

The safe temperature window for both species falls between 27°C and 28°C. Aim for the midpoint of this range (around 27.5°C) for optimal comfort.

The pH requirements of Peacock Cichlid (Aulonocara) (7.8–8.6) and Uaru (5–7) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Peacock Cichlid (Aulonocara) needs 10–25 dGH while Uaru requires 1–8 dGH. An aquarium test kit is recommended for monitoring.

To house Peacock Cichlid (Aulonocara) and Uaru together, plan for an aquarium of at least 480 litres with a minimum length of 150 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.
