Can Afra Cichlid and Pacific Sturgeon Live Together?

Not Recommended

Afra Cichlid and Pacific Sturgeon 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 Afra Cichlid 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

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

Afra Cichlid 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.

Water Parameters

There is no temperature overlap between Afra Cichlid (24–28Β°C) and Pacific Sturgeon (10–22Β°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 Afra Cichlid 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), 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.

Frequently Asked Questions

Can Afra Cichlid and Pacific Sturgeon live together?

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

What size tank do Afra Cichlid 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 Afra Cichlid and Pacific Sturgeon together?

Unfortunately, there is no temperature range that satisfies both species. Afra Cichlid requires 24–28Β°C, while Pacific Sturgeon needs 10–22Β°C.

Are Afra Cichlid or Pacific Sturgeon aggressive?

Afra Cichlid is semi-aggressive (8/10) and Pacific Sturgeon is generally mild-mannered (3/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Afra Cichlid and Pacific Sturgeon need?

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

How do I manage Afra Cichlid's territorial behaviour?

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