Can Auratus Cichlid (Mbuna) and Checker Barb Live Together?

Auratus Cichlid (Mbuna) is a highly aggressive species (9/10), while Checker Barb is peaceful (2/10). This notable difference means Auratus Cichlid (Mbuna) may occasionally assert dominance over Checker Barb.

Large aggression gap (7 points) between Auratus Cichlid (Mbuna) and Checker Barb increases stress risk for the more peaceful fish.

Auratus Cichlid (Mbuna) and Checker Barb 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.

The safe temperature window for both species falls between 23°C and 25°C. Aim for the midpoint of this range (around 24.0°C) for optimal comfort.

The pH requirements of Auratus Cichlid (Mbuna) (7.6–8.6) and Checker Barb (6–7.5) 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.

To house Auratus Cichlid (Mbuna) and Checker Barb together, plan for an aquarium of at least 257 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), Plants - Densely covered. Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Auratus Cichlid (Mbuna) is a plant destroyer, which conflicts with Checker Barb's requirement for live plants. Compromise where possible or prioritise the more critical need.

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 Checker Barb 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.
