Can Aequidens sp. Atabapo and Walking Catfish (Clarias) Live Together?
Keeping Aequidens sp. Atabapo and Walking Catfish (Clarias) together is possible but requires caution, though some care is needed. Provide a spacious tank of at least 750 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.
At a Glance
Can your tank handle Aequidens sp. Atabapo and Walking Catfish (Clarias)?
Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.

Behaviour & Temperament
Aequidens sp. Atabapo is a moderately assertive species (6/10), while Walking Catfish (Clarias) is semi-aggressive (8/10). This modest difference means Walking Catfish (Clarias) may occasionally assert dominance over Aequidens sp. Atabapo.
Aequidens sp. Atabapo and Walking Catfish (Clarias) 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: Walking Catfish (Clarias) is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Walking Catfish (Clarias) is a known jumper, so a tight-fitting lid is essential.
To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Aequidens sp. Atabapo and Walking Catfish (Clarias) to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations.
Water Parameters
The safe temperature window for both species falls between 25°C and 28°C. Aim for the midpoint of this range (around 26.5°C) for optimal comfort.
Both fish can tolerate a pH between 5.5 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 2–8 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house Aequidens sp. Atabapo and Walking Catfish (Clarias) together, plan for an aquarium of at least 750 litres with a minimum length of 180 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.
Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.
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.

Frequently Asked Questions
Can Aequidens sp. Atabapo and Walking Catfish (Clarias) live together?
They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 750 litres), plenty of hiding spots, and watch for signs of stress or aggression.
What size tank do Aequidens sp. Atabapo and Walking Catfish (Clarias) need?
A minimum of 750 litres (tank length at least 180 cm) is recommended. This provides enough space for both species to establish their own areas and reduces the likelihood of territorial disputes.
What water temperature is best for Aequidens sp. Atabapo and Walking Catfish (Clarias) together?
Keep the aquarium between 25°C and 28°C. A target of around 26.5°C sits comfortably within both species' preferred ranges.
Are Aequidens sp. Atabapo or Walking Catfish (Clarias) aggressive?
Aequidens sp. Atabapo is moderately assertive (6/10) and Walking Catfish (Clarias) is semi-aggressive (8/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Aequidens sp. Atabapo and Walking Catfish (Clarias) need?
Both species overlap in the 5.5–7 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
How do I manage Aequidens sp. Atabapo's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Aequidens sp. Atabapo space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
Does Walking Catfish (Clarias) being nocturnal affect compatibility?
Walking Catfish (Clarias) is most active after lights-out, which naturally reduces daytime encounters with its tank mate. This can actually be beneficial, as both fish get undisturbed time to feed and explore. Just ensure food reaches Walking Catfish (Clarias) during evening hours.
