Can Shovelnose Sturgeon and Yellow Bullhead Catfish Live Together?

Shovelnose Sturgeon is a generally mild-mannered species (3/10), while Yellow Bullhead Catfish is moderately assertive (6/10). This modest difference means Yellow Bullhead Catfish may occasionally assert dominance over Shovelnose Sturgeon.

Shovelnose Sturgeon and Yellow Bullhead Catfish 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: Yellow Bullhead Catfish is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Shovelnose Sturgeon is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 10°C and 22°C. Aim for the midpoint of this range (around 16.0°C) for optimal comfort.

Both fish can tolerate a pH between 6.8 and 8. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 8–20 dGH. Regular testing will ensure conditions stay within this range.

To house Shovelnose Sturgeon and Yellow Bullhead Catfish together, plan for an aquarium of at least 3000 litres with a minimum length of 300 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), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.

Both species do well with high (river/stream) water movement, so a standard filtration setup rated for the tank volume should suffice.

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Shovelnose Sturgeon and Yellow Bullhead Catfish need extra room, more cover, and closer observation during the first few weeks so small aggression, feeding, or territory issues do not snowball into a long-term problem.
