Can Banded Gourami and Demasoni Cichlid (Mbuna) Live Together?

Banded Gourami is a generally mild-mannered species (4/10), while Demasoni Cichlid (Mbuna) is highly aggressive (9/10). This notable difference means Demasoni Cichlid (Mbuna) may occasionally assert dominance over Banded Gourami.

Banded Gourami and Demasoni Cichlid (Mbuna) both frequent the 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.

Worth noting: Banded Gourami is a known jumper, so a tight-fitting lid is essential.

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 Banded Gourami (6–7.5) and Demasoni Cichlid (Mbuna) (7.6–8.6) 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.

To house Banded Gourami and Demasoni Cichlid (Mbuna) together, plan for an aquarium of at least 200 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: Plants - Densely covered, Plants - Floating, Sand (Sifters), Established Algae (Otocinclus). Meeting these requirements will help both species thrive.

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

Banded Gourami prefers Low (Still Water) flow while Demasoni Cichlid (Mbuna) needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.

Banded Gourami and Demasoni Cichlid (Mbuna) 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.
