Can Demasoni Cichlid (Mbuna) and Tinfoil Barb Live Together?

Demasoni Cichlid (Mbuna) is a highly aggressive species (9/10), while Tinfoil Barb is generally mild-mannered (3/10). This notable difference means Demasoni Cichlid (Mbuna) may occasionally assert dominance over Tinfoil Barb.

Large aggression gap (6 points) between Demasoni Cichlid (Mbuna) and Tinfoil Barb increases stress risk for the more peaceful fish.

Demasoni Cichlid (Mbuna) and Tinfoil Barb both frequent the Bottom (Substrate) and 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: Tinfoil Barb 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 Demasoni Cichlid (Mbuna) (7.6–8.6) and Tinfoil Barb (6.5–7.5) 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. An aquarium test kit is recommended for monitoring.

To house Demasoni Cichlid (Mbuna) and Tinfoil Barb together, plan for an aquarium of at least 816 litres with a minimum length of 180 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), Established Algae (Otocinclus), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Both species do well with high (river/stream) water movement, so a standard filtration setup rated for the tank volume should suffice.
