Can Peacock Bass Temensis and Shovelnose Sturgeon Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 11, 2026
Not Recommended

Peacock Bass Temensis and Shovelnose Sturgeon are not recommended as tank mates due to no temperature overlap. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Can your tank handle Peacock Bass Temensis 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

Peacock Bass Temensis is a semi-aggressive species (7/10), while Shovelnose Sturgeon is generally mild-mannered (3/10). This notable difference means Peacock Bass Temensis may occasionally assert dominance over Shovelnose Sturgeon.

In terms of spatial distribution, Peacock Bass Temensis prefers the Middle (Open Water) and Top (Surface) 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: Peacock Bass Temensis is a known jumper, so a tight-fitting lid is essential.

Water Parameters

There is no temperature overlap between Peacock Bass Temensis (26–30°C) and Shovelnose Sturgeon (10–22°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 6.8 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 8–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Peacock Bass Temensis 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: 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.

Why This Pairing Usually Fails in Practice

Peacock Bass Temensis 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.

Frequently Asked Questions

Can Peacock Bass Temensis and Shovelnose Sturgeon live together?

No. This combination is not recommended. Key incompatibilities — such as non-overlapping temperature ranges — make cohabitation unsafe.

What size tank do Peacock Bass Temensis 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 Peacock Bass Temensis and Shovelnose Sturgeon together?

Unfortunately, there is no temperature range that satisfies both species. Peacock Bass Temensis requires 26–30°C, while Shovelnose Sturgeon needs 10–22°C.

Are Peacock Bass Temensis or Shovelnose Sturgeon aggressive?

Peacock Bass Temensis is semi-aggressive (7/10) and Shovelnose Sturgeon is generally mild-mannered (3/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Peacock Bass Temensis and Shovelnose Sturgeon need?

Both species overlap in the 6.8–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
