Can Shovelnose Sturgeon and Whiteseam Fighter Live Together?

Both Shovelnose Sturgeon and Whiteseam Fighter are generally mild-mannered species with an aggression score of 3/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.

Shovelnose Sturgeon and Whiteseam Fighter 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.

There is a critical concern: the Piscivore (Eats small/nano fish) behaviour of one fish directly conflicts with the Nano / Bite-sized (Predation Risk) trait of the other — piscivorous fish will prey on nano-sized tank mates..

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion. Shrimp eaters may also prey on very small nano fish.

Worth noting: Shovelnose Sturgeon is a known jumper, so a tight-fitting lid is essential.

There is no temperature overlap between Shovelnose Sturgeon (10–22°C) and Whiteseam Fighter (23–28°C). This fundamental mismatch makes long-term cohabitation impractical.

The pH requirements of Shovelnose Sturgeon (6.8–8) and Whiteseam Fighter (4–6.5) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Shovelnose Sturgeon needs 8–20 dGH while Whiteseam Fighter requires 1–5 dGH.

To house Shovelnose Sturgeon and Whiteseam Fighter 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: Sand (Sifters), Smooth Gravel (Sensitive Barbels), Leaf Litter/Blackwater, Plants - Densely covered, Plants - Floating. Meeting these requirements will help both species thrive.

Shovelnose Sturgeon prefers High (River/Stream) flow while Whiteseam Fighter needs Low (Still Water) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.

Shovelnose Sturgeon and Whiteseam Fighter 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.

Feeding time deserves special attention with this pairing. Shovelnose Sturgeon is a known shrimp eater and may prey on small invertebrates or nano fish like Whiteseam Fighter.
