Can Aequidens sp. Atabapo and Altolamprologus Compressiceps Live Together?

Not Recommended

Aequidens sp. Atabapo and Altolamprologus Compressiceps are not recommended as tank mates due to conflicting pH requirements and incompatible hardness ranges. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Can your tank handle Aequidens sp. Atabapo and Altolamprologus Compressiceps?

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

Both Aequidens sp. Atabapo and Altolamprologus Compressiceps are moderately assertive species with an aggression score of 6/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.

Aequidens sp. Atabapo and Altolamprologus Compressiceps both frequent the Middle (Open Water) and 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.

Additional behavioural considerations to keep in mind: Two territorial species may clash over territory, especially in smaller tanks.

Water Parameters

The safe temperature window for both species falls between 25Β°C and 27Β°C. Aim for the midpoint of this range (around 26.0Β°C) for optimal comfort.

The pH requirements of Aequidens sp. Atabapo (4.5–7) and Altolamprologus Compressiceps (7.8–9) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Aequidens sp. Atabapo needs 1–8 dGH while Altolamprologus Compressiceps requires 10–25 dGH.

Tank Setup

To house Aequidens sp. Atabapo and Altolamprologus Compressiceps together, plan for an aquarium of at least 153 litres with a minimum length of 90 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), Driftwood (Digestion/Hiding), Leaf Litter/Blackwater, Shells (Breeding/Hiding). Meeting these requirements will help both species thrive.

Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

Frequently Asked Questions

Can Aequidens sp. Atabapo and Altolamprologus Compressiceps live together?

No. This combination is not recommended. Key incompatibilities β€” such as critical behavioural conflicts β€” make cohabitation unsafe.

What size tank do Aequidens sp. Atabapo and Altolamprologus Compressiceps need?

A minimum of 153 litres (tank length at least 90 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 Aequidens sp. Atabapo and Altolamprologus Compressiceps together?

Keep the aquarium between 25Β°C and 27Β°C. A target of around 26.0Β°C sits comfortably within both species' preferred ranges.

Are Aequidens sp. Atabapo or Altolamprologus Compressiceps aggressive?

Aequidens sp. Atabapo is moderately assertive (6/10) and Altolamprologus Compressiceps is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Aequidens sp. Atabapo and Altolamprologus Compressiceps need?

Their pH requirements do not overlap. Aequidens sp. Atabapo prefers 4.5–7, while Altolamprologus Compressiceps needs 7.8–9. This makes them incompatible in the same water chemistry.

How do I manage Aequidens sp. Atabapo's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Aequidens sp. Atabapo 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.
