Can African Jewel Cichlid and Fosso Cichlid (Fossorochromis rostratus) Live Together?
African Jewel Cichlid and Fosso Cichlid (Fossorochromis rostratus) 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 Jewel Cichlid and Fosso Cichlid (Fossorochromis rostratus)?
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 Jewel Cichlid is a semi-aggressive species (8/10), while Fosso Cichlid (Fossorochromis rostratus) is moderately assertive (6/10). This modest difference means African Jewel Cichlid may occasionally assert dominance over Fosso Cichlid (Fossorochromis rostratus).
African Jewel Cichlid and Fosso Cichlid (Fossorochromis rostratus) 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 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.
The pH requirements of African Jewel Cichlid (6.5–7.5) and Fosso Cichlid (Fossorochromis rostratus) (7.8–8.6) 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 Jewel Cichlid and Fosso Cichlid (Fossorochromis rostratus) together, plan for an aquarium of at least 680 litres with a minimum length of 180 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.
Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.
Suitable Tank Sizes
Standard aquarium sizes large enough for both African Jewel Cichlid and Fosso Cichlid (Fossorochromis rostratus).

Frequently Asked Questions
Can African Jewel Cichlid and Fosso Cichlid (Fossorochromis rostratus) live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do African Jewel Cichlid and Fosso Cichlid (Fossorochromis rostratus) need?
A minimum of 680 litres (tank length at least 180 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 Jewel Cichlid and Fosso Cichlid (Fossorochromis rostratus) together?
Keep the aquarium between 24°C and 28°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.
Are African Jewel Cichlid or Fosso Cichlid (Fossorochromis rostratus) aggressive?
African Jewel Cichlid is semi-aggressive (8/10) and Fosso Cichlid (Fossorochromis rostratus) is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do African Jewel Cichlid and Fosso Cichlid (Fossorochromis rostratus) need?
Their pH requirements do not overlap. African Jewel Cichlid prefers 6.5–7.5, while Fosso Cichlid (Fossorochromis rostratus) needs 7.8–8.6. This makes them incompatible in the same water chemistry.
How do I manage African Jewel Cichlid's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives African Jewel 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.
