Can Rosy Red Minnow / Fathead Minnow and Shovelnose Sturgeon Live Together?

Rosy Red Minnow / Fathead Minnow is a peaceful species (1/10), while Shovelnose Sturgeon is generally mild-mannered (3/10). This modest difference means Shovelnose Sturgeon may occasionally assert dominance over Rosy Red Minnow / Fathead Minnow.

In terms of spatial distribution, Rosy Red Minnow / Fathead Minnow prefers the Top (Surface) and Middle (Open Water) zones, whereas Shovelnose Sturgeon occupies the Bottom (Substrate) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

Worth noting: 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 Rosy Red Minnow / Fathead Minnow and Shovelnose Sturgeon 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.

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: Smooth Gravel (Sensitive Barbels), Sand (Sifters). 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.

Rosy Red Minnow / Fathead Minnow and Shovelnose Sturgeon work best when the tank gives each fish enough room to use its preferred level of the aquarium and enough cover to avoid constant visual contact. The score matters, but the real-world success usually comes from matching their pace, keeping water stable, and resisting the urge to crowd the tank just because the pair looks safe on paper.
