Can African Butterfly Cichlid and Altolamprologus Calvus Live Together?
African Butterfly Cichlid and Altolamprologus Calvus are not recommended as tank mates due to conflicting pH requirements. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.
At a Glance
Can your tank handle African Butterfly Cichlid and Altolamprologus Calvus?
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
African Butterfly Cichlid is a generally mild-mannered species (3/10), while Altolamprologus Calvus is moderately assertive (5/10). This modest difference means Altolamprologus Calvus may occasionally assert dominance over African Butterfly Cichlid.
African Butterfly Cichlid and Altolamprologus Calvus 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: Hyperactive swimmers can stress shy, slow-moving species through constant motion. Two territorial species may clash over territory, especially in smaller tanks.
Water Parameters
The safe temperature window for both species falls between 24°C and 27°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.
The pH requirements of African Butterfly Cichlid (5.5–7.5) and Altolamprologus Calvus (7.8–9) do not overlap, making it impossible to satisfy both species simultaneously.
For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house African Butterfly Cichlid and Altolamprologus Calvus together, plan for an aquarium of at least 114 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), Smooth Gravel (Sensitive Barbels), Plants - Densely covered, Driftwood (Digestion/Hiding), Shells (Breeding/Hiding). 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 African Butterfly Cichlid and Altolamprologus Calvus live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do African Butterfly Cichlid and Altolamprologus Calvus need?
A minimum of 114 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 African Butterfly Cichlid and Altolamprologus Calvus together?
Keep the aquarium between 24°C and 27°C. A target of around 25.5°C sits comfortably within both species' preferred ranges.
Are African Butterfly Cichlid or Altolamprologus Calvus aggressive?
African Butterfly Cichlid is generally mild-mannered (3/10) and Altolamprologus Calvus is moderately assertive (5/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do African Butterfly Cichlid and Altolamprologus Calvus need?
Their pH requirements do not overlap. African Butterfly Cichlid prefers 5.5–7.5, while Altolamprologus Calvus needs 7.8–9. This makes them incompatible in the same water chemistry.
How do I manage African Butterfly Cichlid's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives African Butterfly Cichlid space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
