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

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

Large aggression gap (7 points) between Demasoni Cichlid (Mbuna) and Honey Gourami increases stress risk for the more peaceful fish.

Demasoni Cichlid (Mbuna) and Honey Gourami 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.

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.

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 Demasoni Cichlid (Mbuna) (7.6–8.6) and Honey Gourami (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 Demasoni Cichlid (Mbuna) and Honey Gourami 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: Sand (Sifters), Established Algae (Otocinclus), Plants - Densely covered, Plants - Floating, Smooth Gravel (Sensitive Barbels). 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 Honey Gourami's requirement for live plants. Compromise where possible or prioritise the more critical need.

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

Demasoni Cichlid (Mbuna) and Honey Gourami 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.
