Can Agassiz's Dwarf Cichlid and Peacock Cichlid (Aulonocara) Live Together?

Agassiz's Dwarf Cichlid is a moderately assertive species (5/10), while Peacock Cichlid (Aulonocara) is moderately assertive (6/10). This modest difference means Peacock Cichlid (Aulonocara) may occasionally assert dominance over Agassiz's Dwarf Cichlid.

Agassiz's Dwarf Cichlid and Peacock Cichlid (Aulonocara) both frequent the 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.

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 Agassiz's Dwarf Cichlid (4.5–7) and Peacock Cichlid (Aulonocara) (7.8–8.6) do not overlap, making it impossible to satisfy both species simultaneously.

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

To house Agassiz's Dwarf 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), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Plants - Densely covered, Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

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