Can American Grass Shrimp and Shovelnose Sturgeon Live Together?
American Grass Shrimp and Shovelnose Sturgeon are not recommended as tank mates due to piscivorous fish will prey on nano-sized tank mates.. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.
At a Glance
Can your tank handle American Grass Shrimp and Shovelnose Sturgeon?
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
American Grass Shrimp 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 American Grass Shrimp.
American Grass Shrimp and Shovelnose Sturgeon 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 Nano / Bite-sized (Predation Risk) behaviour of one fish directly conflicts with the Piscivore (Eats small/nano fish) trait of the other — piscivorous fish will prey on nano-sized tank mates..
Additional behavioural considerations to keep in mind: Shrimp eaters may also prey on very small nano fish.
Worth noting: American Grass Shrimp is a known jumper, so a tight-fitting lid is essential.
Water Parameters
The safe temperature window for both species falls between 15°C and 22°C. Aim for the midpoint of this range (around 18.5°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 8–15 dGH. Regular testing will ensure conditions stay within this range.
Tank Setup
To house American Grass Shrimp 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: Plants - Densely covered, Leaf Litter/Blackwater, 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
American Grass Shrimp and Shovelnose Sturgeon 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.
Diet & Feeding
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 American Grass Shrimp.
Frequently Asked Questions
Can American Grass Shrimp and Shovelnose Sturgeon live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do American Grass Shrimp and Shovelnose Sturgeon need?
A minimum of 3000 litres (tank length at least 300 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 American Grass Shrimp and Shovelnose Sturgeon together?
Keep the aquarium between 15°C and 22°C. A target of around 18.5°C sits comfortably within both species' preferred ranges.
Are American Grass Shrimp or Shovelnose Sturgeon aggressive?
American Grass Shrimp is peaceful (1/10) and Shovelnose Sturgeon is generally mild-mannered (3/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do American Grass Shrimp and Shovelnose Sturgeon need?
Both species overlap in the 6.8–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
