Can African Pike and Pacific Sturgeon Live Together?

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

In terms of spatial distribution, African Pike 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: African Pike is a known jumper, so a tight-fitting lid is essential.

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

Both fish can tolerate a pH between 6.5 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 4–15 dGH. Regular testing will ensure conditions stay within this range.

To house African Pike 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.

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 - Floating, Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding), Sand (Sifters). 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.
