Can Auratus Cichlid (Mbuna) and Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) Live Together?

Auratus Cichlid (Mbuna) is a highly aggressive species (9/10), while Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) is generally mild-mannered (4/10). This notable difference means Auratus Cichlid (Mbuna) may occasionally assert dominance over Barlow's Dwarf Cichlid (Apistogramma Maulbrüter).

Auratus Cichlid (Mbuna) and Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) 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: Aggressive fish may bully and stress shy, slow-moving species. Hyperactive swimmers can stress shy, slow-moving species through constant motion. Two territorial species may clash over territory, especially in smaller tanks.

The safe temperature window for both species falls between 23°C and 28°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

The pH requirements of Auratus Cichlid (Mbuna) (7.6–8.6) and Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) (4.5–6.5) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Auratus Cichlid (Mbuna) needs 10–25 dGH while Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) requires 1–5 dGH.

To house Auratus Cichlid (Mbuna) and Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) together, plan for an aquarium of at least 252 litres with a minimum length of 120 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

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), Established Algae (Otocinclus), Driftwood (Digestion/Hiding), Leaf Litter/Blackwater. 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.

Auratus Cichlid (Mbuna) and Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.
