Can Duboisi Cichlid (Tropheus) and Freshwater Angelfish Live Together?

🔴Not Recommended

Duboisi Cichlid (Tropheus) and Freshwater Angelfish 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.

Behaviour & Temperament

Duboisi Cichlid (Tropheus) is a semi-aggressive species (8/10), while Freshwater Angelfish is moderately assertive (6/10). This modest difference means Duboisi Cichlid (Tropheus) may occasionally assert dominance over Freshwater Angelfish.

Duboisi Cichlid (Tropheus) and Freshwater Angelfish both frequent the Middle (Open Water) 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 Duboisi Cichlid (Tropheus) (8–9) and Freshwater Angelfish (6–7.8) 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. An aquarium test kit is recommended for monitoring.

Tank Setup

To house Duboisi Cichlid (Tropheus) and Freshwater Angelfish together, plan for an aquarium of at least 336 litres with a minimum length of 120 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

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), Plants - Densely covered, Driftwood (Digestion/Hiding), Plants - lighly covered. Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Duboisi Cichlid (Tropheus) is a plant destroyer, which conflicts with Freshwater Angelfish's requirement for live plants. Compromise where possible or prioritise the more critical need.

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 Duboisi Cichlid (Tropheus) and Freshwater Angelfish live together?

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

What size tank do Duboisi Cichlid (Tropheus) and Freshwater Angelfish need?

A minimum of 336 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 Duboisi Cichlid (Tropheus) and Freshwater Angelfish 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 Duboisi Cichlid (Tropheus) or Freshwater Angelfish aggressive?

Duboisi Cichlid (Tropheus) is semi-aggressive (8/10) and Freshwater Angelfish is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Duboisi Cichlid (Tropheus) and Freshwater Angelfish need?

Their pH requirements do not overlap. Duboisi Cichlid (Tropheus) prefers 8–9, while Freshwater Angelfish needs 6–7.8. This makes them incompatible in the same water chemistry.

Will Freshwater Angelfish nip Duboisi Cichlid (Tropheus)'s fins?

Freshwater Angelfish is a known fin nipper. If Duboisi Cichlid (Tropheus) has long or flowing fins, there is a real risk of fin damage. Keeping Freshwater Angelfish in a larger group can help redirect nipping behaviour toward conspecifics.

How do I manage Duboisi Cichlid (Tropheus)'s territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Duboisi Cichlid (Tropheus) 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.
