Can Shovelnose Sturgeon and Sunset Hap Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 11, 2026
Not Recommended

Shovelnose Sturgeon and Sunset Hap 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 Shovelnose Sturgeon and Sunset Hap?

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

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

Shovelnose Sturgeon and Sunset Hap 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: Shovelnose Sturgeon is a known jumper, so a tight-fitting lid is essential.

Water Parameters

There is no temperature overlap between Shovelnose Sturgeon (10–22°C) and Sunset Hap (24–28°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 7.6 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 10–20 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Shovelnose Sturgeon and Sunset Hap 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). 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

Shovelnose Sturgeon and Sunset Hap 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 Shovelnose Sturgeon and Sunset Hap live together?

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

What size tank do Shovelnose Sturgeon and Sunset Hap 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 Shovelnose Sturgeon and Sunset Hap together?

Unfortunately, there is no temperature range that satisfies both species. Shovelnose Sturgeon requires 10–22°C, while Sunset Hap needs 24–28°C.

Are Shovelnose Sturgeon or Sunset Hap aggressive?

Shovelnose Sturgeon is generally mild-mannered (3/10) and Sunset Hap is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Shovelnose Sturgeon and Sunset Hap need?

Both species overlap in the 7.6–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

How do I manage Sunset Hap's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Sunset Hap space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
