Can your tank handle Buccochromis rhoadesii and Chao Phraya Giant Catfish (Paroon Shark)?

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

Both Buccochromis rhoadesii and Chao Phraya Giant Catfish (Paroon Shark) are semi-aggressive species with an aggression score of 8/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.

Both Buccochromis rhoadesii and Chao Phraya Giant Catfish (Paroon Shark) are highly aggressive, increasing the risk of violent confrontations.

Buccochromis rhoadesii and Chao Phraya Giant Catfish (Paroon Shark) 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: Chao Phraya Giant Catfish (Paroon Shark) is a known jumper, so a tight-fitting lid is essential.

Water Parameters

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 Buccochromis rhoadesii (7.8–8.6) and Chao Phraya Giant Catfish (Paroon Shark) (6.5–7.5) do not overlap, making it impossible to satisfy both species simultaneously.

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

Tank Setup

To house Buccochromis rhoadesii and Chao Phraya Giant Catfish (Paroon Shark) together, plan for an aquarium of at least 15000 litres with a minimum length of 600 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), Smooth Gravel (Sensitive Barbels). 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.

Why This Pairing Usually Fails in Practice

Buccochromis rhoadesii and Chao Phraya Giant Catfish (Paroon Shark) 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.

Frequently Asked Questions

Can Buccochromis rhoadesii and Chao Phraya Giant Catfish (Paroon Shark) live together?

No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.

What size tank do Buccochromis rhoadesii and Chao Phraya Giant Catfish (Paroon Shark) need?

A minimum of 15000 litres (tank length at least 600 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 Buccochromis rhoadesii and Chao Phraya Giant Catfish (Paroon Shark) together?

Keep the aquarium between 24°C and 28°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.

Are Buccochromis rhoadesii or Chao Phraya Giant Catfish (Paroon Shark) aggressive?

Buccochromis rhoadesii is semi-aggressive (8/10) and Chao Phraya Giant Catfish (Paroon Shark) is semi-aggressive (8/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Buccochromis rhoadesii and Chao Phraya Giant Catfish (Paroon Shark) need?

Their pH requirements do not overlap. Buccochromis rhoadesii prefers 7.8–8.6, while Chao Phraya Giant Catfish (Paroon Shark) needs 6.5–7.5. This makes them incompatible in the same water chemistry.

How do I manage Buccochromis rhoadesii's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Buccochromis rhoadesii 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.
