Can Socolofi Cichlid (Pseudotropheus Socolofi) and Twig Catfish Live Together?

Socolofi Cichlid (Pseudotropheus Socolofi) is a semi-aggressive species (8/10), while Twig Catfish is peaceful (0/10). This notable difference means Socolofi Cichlid (Pseudotropheus Socolofi) may occasionally assert dominance over Twig Catfish.

Large aggression gap (8 points) between Socolofi Cichlid (Pseudotropheus Socolofi) and Twig Catfish increases stress risk for the more peaceful fish.

Socolofi Cichlid (Pseudotropheus Socolofi) and Twig Catfish both frequent the Middle (Open Water) and 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.

Worth noting: Twig Catfish is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

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 Socolofi Cichlid (Pseudotropheus Socolofi) (7.6–8.6) and Twig Catfish (6–7.5) do not overlap, making it impossible to satisfy both species simultaneously.

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

To house Socolofi Cichlid (Pseudotropheus Socolofi) and Twig Catfish together, plan for an aquarium of at least 268 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), Established Algae (Otocinclus), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding), Plants - Densely covered. 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 Twig Catfish's requirement for live plants. Compromise where possible or prioritise the more critical need.

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

Socolofi Cichlid (Pseudotropheus Socolofi) and Twig Catfish 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.
