Can Blue Point Cichlid and Duboisi Cichlid (Tropheus) Live Together?
Blue Point Cichlid and Duboisi Cichlid (Tropheus) 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 Blue Point Cichlid and Duboisi Cichlid (Tropheus)?
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
Blue Point Cichlid is a moderately assertive species (6/10), while Duboisi Cichlid (Tropheus) is semi-aggressive (8/10). This modest difference means Duboisi Cichlid (Tropheus) may occasionally assert dominance over Blue Point Cichlid.
Blue Point Cichlid and Duboisi Cichlid (Tropheus) 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 Blue Point Cichlid (6–7.8) and Duboisi Cichlid (Tropheus) (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 Blue Point Cichlid and Duboisi Cichlid (Tropheus) together, plan for an aquarium of at least 328 litres with a minimum length of 120 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, Established Algae (Otocinclus), Smooth Gravel (Sensitive Barbels). 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 Blue Point Cichlid and Duboisi Cichlid (Tropheus) live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Blue Point Cichlid and Duboisi Cichlid (Tropheus) need?
A minimum of 328 litres (tank length at least 120 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 Blue Point Cichlid and Duboisi Cichlid (Tropheus) 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 Blue Point Cichlid or Duboisi Cichlid (Tropheus) aggressive?
Blue Point Cichlid is moderately assertive (6/10) and Duboisi Cichlid (Tropheus) is semi-aggressive (8/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Blue Point Cichlid and Duboisi Cichlid (Tropheus) need?
Their pH requirements do not overlap. Blue Point Cichlid prefers 6–7.8, while Duboisi Cichlid (Tropheus) needs 8–9. This makes them incompatible in the same water chemistry.
How do I manage Blue Point Cichlid's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Blue Point 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.
