Can Buettikoferi Bichir and Tropheus Moorii Live Together?

Buettikoferi Bichir is a moderately assertive species (6/10), while Tropheus Moorii is highly aggressive (9/10). This modest difference means Tropheus Moorii may occasionally assert dominance over Buettikoferi Bichir.

Buettikoferi Bichir and Tropheus Moorii 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.

Worth noting: Buettikoferi Bichir is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Buettikoferi Bichir 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 Buettikoferi Bichir (6.5–7.5) and Tropheus Moorii (8–9.5) 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 Buettikoferi Bichir and Tropheus Moorii together, plan for an aquarium of at least 373 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), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding), Established Algae (Otocinclus). Meeting these requirements will help both species thrive.

Buettikoferi Bichir prefers Low (Still Water) flow while Tropheus Moorii needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.

Buettikoferi Bichir and Tropheus Moorii 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.
