Can Mokele-mbembe Bichir and Socolofi Cichlid (Pseudotropheus Socolofi) Live Together?

Mokele-mbembe Bichir is a moderately assertive species (6/10), while Socolofi Cichlid (Pseudotropheus Socolofi) is semi-aggressive (8/10). This modest difference means Socolofi Cichlid (Pseudotropheus Socolofi) may occasionally assert dominance over Mokele-mbembe Bichir.

Mokele-mbembe Bichir and Socolofi Cichlid (Pseudotropheus Socolofi) 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: Mokele-mbembe Bichir is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Mokele-mbembe 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 Mokele-mbembe Bichir (6.5–7.5) and Socolofi Cichlid (Pseudotropheus Socolofi) (7.6–8.6) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–19 dGH. Regular testing will ensure conditions stay within this range.

To house Mokele-mbembe Bichir and Socolofi Cichlid (Pseudotropheus Socolofi) together, plan for an aquarium of at least 336 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), Plants - Densely covered, Established Algae (Otocinclus). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Socolofi Cichlid (Pseudotropheus Socolofi) is a plant destroyer, which conflicts with Mokele-mbembe Bichir's requirement for live plants. Compromise where possible or prioritise the more critical need.

Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

Mokele-mbembe Bichir and Socolofi Cichlid (Pseudotropheus Socolofi) 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.
