Can Agassiz's Dwarf Cichlid and Demasoni Cichlid (Mbuna) Live Together?

Agassiz's Dwarf Cichlid is a moderately assertive species (5/10), while Demasoni Cichlid (Mbuna) is highly aggressive (9/10). This notable difference means Demasoni Cichlid (Mbuna) may occasionally assert dominance over Agassiz's Dwarf Cichlid.

Agassiz's Dwarf Cichlid and Demasoni Cichlid (Mbuna) 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: 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 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 Demasoni Cichlid (Mbuna) (7.6–8.6) do not overlap, making it impossible to satisfy both species simultaneously.

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

To house Agassiz's Dwarf Cichlid and Demasoni Cichlid (Mbuna) 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, 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 Agassiz's Dwarf Cichlid's requirement for live plants. Compromise where possible or prioritise the more critical need.

Agassiz's Dwarf Cichlid 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.
