Can Elongatus Cichlid (Pseudotropheus Elongatus) and Shovelnose Sturgeon Live Together?

Elongatus Cichlid (Pseudotropheus Elongatus) is a semi-aggressive species (8/10), while Shovelnose Sturgeon is generally mild-mannered (3/10). This notable difference means Elongatus Cichlid (Pseudotropheus Elongatus) may occasionally assert dominance over Shovelnose Sturgeon.

Elongatus Cichlid (Pseudotropheus Elongatus) and Shovelnose 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: Shovelnose Sturgeon is a known jumper, so a tight-fitting lid is essential.

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

Both fish can tolerate a pH between 7.5 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 10–20 dGH. Regular testing will ensure conditions stay within this range.

To house Elongatus Cichlid (Pseudotropheus Elongatus) 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), Established Algae (Otocinclus), Smooth Gravel (Sensitive Barbels). 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.

Elongatus Cichlid (Pseudotropheus Elongatus) 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.
