Can African Lungfish and Pacific Sturgeon Live Together?

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

Large aggression gap (7 points) between African Lungfish and Pacific Sturgeon increases stress risk for the more peaceful fish.

African Lungfish and Pacific 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.

Worth noting: African Lungfish is a known jumper, so a tight-fitting lid is essential.

There is no temperature overlap between African Lungfish (24–30°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 8. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–20 dGH. Regular testing will ensure conditions stay within this range.

To house African Lungfish 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: Sand (Sifters), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.

African Lungfish prefers Low (Still Water) flow while Pacific Sturgeon needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.
