Can Bucktooth Tetra (Exodon) and Socolofi Cichlid (Pseudotropheus Socolofi) Live Together?

Bucktooth Tetra (Exodon) is a highly aggressive species (9/10), while Socolofi Cichlid (Pseudotropheus Socolofi) is semi-aggressive (8/10). This modest difference means Bucktooth Tetra (Exodon) may occasionally assert dominance over Socolofi Cichlid (Pseudotropheus Socolofi).

Both Bucktooth Tetra (Exodon) and Socolofi Cichlid (Pseudotropheus Socolofi) are highly aggressive, increasing the risk of violent confrontations.

Bucktooth Tetra (Exodon) and Socolofi Cichlid (Pseudotropheus Socolofi) 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: Two aggressive species housed together increases risk of fighting.

Worth noting: Bucktooth Tetra (Exodon) 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 Bucktooth Tetra (Exodon) (5.5–7.5) 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 10–15 dGH. Regular testing will ensure conditions stay within this range.

To house Bucktooth Tetra (Exodon) and Socolofi Cichlid (Pseudotropheus Socolofi) together, plan for an aquarium of at least 379 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: Driftwood (Digestion/Hiding), Sand (Sifters), Established Algae (Otocinclus), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

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

Bucktooth Tetra (Exodon) 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.
