Can Long-Finned African Tetra and Pacific Sturgeon Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 7, 2026
Possible with Caution

Keeping Long-Finned African Tetra and Pacific Sturgeon together is possible but requires caution, though some care is needed. Provide a spacious tank of at least 20000 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.

Can your tank handle Long-Finned African Tetra and Pacific 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

Long-Finned African Tetra is a peaceful species (2/10), while Pacific Sturgeon is generally mild-mannered (3/10). This modest difference means Pacific Sturgeon may occasionally assert dominance over Long-Finned African Tetra.

In terms of spatial distribution, Long-Finned African Tetra prefers the Top (Surface) and Middle (Open Water) zones, whereas Pacific 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: Long-Finned African Tetra is a known jumper, so a tight-fitting lid is essential.

Water Parameters

The safe temperature window for both species falls between 22°C and 22°C. Aim for the midpoint of this range (around 22.0°C) for optimal comfort.

Both fish can tolerate a pH between 6.5 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 5–19 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Long-Finned African Tetra and Pacific Sturgeon together, plan for an aquarium of at least 20000 litres with a minimum length of 600 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Driftwood (Digestion/Hiding), 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 Needs Extra Planning in Practice

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Long-Finned African Tetra and Pacific Sturgeon need extra room, more cover, and closer observation during the first few weeks so small aggression, feeding, or territory issues do not snowball into a long-term problem.

Frequently Asked Questions

Can Long-Finned African Tetra and Pacific Sturgeon live together?

They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 20000 litres), plenty of hiding spots, and watch for signs of stress or aggression.

What size tank do Long-Finned African Tetra and Pacific Sturgeon need?

A minimum of 20000 litres (tank length at least 600 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 Long-Finned African Tetra and Pacific Sturgeon together?

Keep the aquarium between 22°C and 22°C. A target of around 22.0°C sits comfortably within both species' preferred ranges.

Are Long-Finned African Tetra or Pacific Sturgeon aggressive?

Long-Finned African Tetra is peaceful (2/10) and Pacific Sturgeon is generally mild-mannered (3/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Long-Finned African Tetra and Pacific Sturgeon need?

Both species overlap in the 6.5–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
