Can African Pike and Chao Phraya Giant Catfish (Paroon Shark) Live Together?

African Pike is a semi-aggressive species (7/10), while Chao Phraya Giant Catfish (Paroon Shark) is semi-aggressive (8/10). This modest difference means Chao Phraya Giant Catfish (Paroon Shark) may occasionally assert dominance over African Pike.

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

African Pike and Chao Phraya Giant Catfish (Paroon Shark) both frequent the Middle (Open Water) 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: African Pike is a known jumper, so a tight-fitting lid is essential.

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 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 4–15 dGH. Regular testing will ensure conditions stay within this range.

To house African Pike 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.

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: Plants - Floating, 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.
