Can Common Synodontis (False Upside Down Catfish) and Cupid Cichlid Live Together?

Common Synodontis (False Upside Down Catfish) is a generally mild-mannered species (4/10), while Cupid Cichlid is generally mild-mannered (3/10). This modest difference means Common Synodontis (False Upside Down Catfish) may occasionally assert dominance over Cupid Cichlid.

Common Synodontis (False Upside Down Catfish) and Cupid Cichlid 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: Common Synodontis (False Upside Down 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.

Both fish can tolerate a pH between 6.5 and 7. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–8 dGH. Regular testing will ensure conditions stay within this range.

To house Common Synodontis (False Upside Down Catfish) and Cupid Cichlid together, plan for an aquarium of at least 250 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), Driftwood (Digestion/Hiding), Leaf Litter/Blackwater. 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.
