Can Aequidens sp. Atabapo and Peppered Corydoras Live Together?

Aequidens sp. Atabapo is a moderately assertive species (6/10), while Peppered Corydoras is peaceful (0/10). This notable difference means Aequidens sp. Atabapo may occasionally assert dominance over Peppered Corydoras.

Large aggression gap (6 points) between Aequidens sp. Atabapo and Peppered Corydoras increases stress risk for the more peaceful fish.

Aequidens sp. Atabapo and Peppered Corydoras 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.

There is no temperature overlap between Aequidens sp. Atabapo (25–29°C) and Peppered Corydoras (18–24°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 6 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 2–8 dGH. Regular testing will ensure conditions stay within this range.

To house Aequidens sp. Atabapo and Peppered Corydoras together, plan for an aquarium of at least 110 litres with a minimum length of 90 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, Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

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