Behaviour & Temperament

Cuckoo Catfish is a moderately assertive species (5/10), while Pictus Catfish is generally mild-mannered (4/10). This modest difference means Cuckoo Catfish may occasionally assert dominance over Pictus Catfish.

Cuckoo Catfish and Pictus 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.

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

Water Parameters

The safe temperature window for both species falls between 24°C and 26°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

Both fish can tolerate a pH between 7.5 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Cuckoo Catfish and Pictus Catfish together, plan for an aquarium of at least 408 litres with a minimum length of 120 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

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), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding). 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.

Frequently Asked Questions

Can Cuckoo Catfish and Pictus Catfish live together?

Yes. Cuckoo Catfish and Pictus Catfish are considered ideal tank mates. Their water parameters, temperaments, and behaviour profiles are well matched for a community aquarium.

What size tank do Cuckoo Catfish and Pictus Catfish need?

A minimum of 408 litres (tank length at least 120 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 Cuckoo Catfish and Pictus Catfish together?

Keep the aquarium between 24°C and 26°C. A target of around 25.0°C sits comfortably within both species' preferred ranges.

Are Cuckoo Catfish or Pictus Catfish aggressive?

Cuckoo Catfish is moderately assertive (5/10) and Pictus Catfish is generally mild-mannered (4/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Cuckoo Catfish and Pictus Catfish need?

Both species overlap in the 7.5–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Does Cuckoo Catfish being nocturnal affect compatibility?

Cuckoo Catfish 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 Cuckoo Catfish during evening hours.
