Behaviour & Temperament

Duboisi Cichlid (Tropheus) is a semi-aggressive species (8/10), while Flowerhorn Cichlid is highly aggressive (10/10). This modest difference means Flowerhorn Cichlid may occasionally assert dominance over Duboisi Cichlid (Tropheus).

Both Duboisi Cichlid (Tropheus) and Flowerhorn Cichlid are highly aggressive, increasing the risk of violent confrontations.

Duboisi Cichlid (Tropheus) and Flowerhorn Cichlid 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.

To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Duboisi Cichlid (Tropheus) and Flowerhorn Cichlid to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations.

Water Parameters

The safe temperature window for both species falls between 26°C and 28°C. Aim for the midpoint of this range (around 27.0°C) for optimal comfort.

Both fish can tolerate a pH between 8 and 8. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 10–20 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Duboisi Cichlid (Tropheus) and Flowerhorn Cichlid 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.

Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Sand (Sifters), Established Algae (Otocinclus), Smooth Gravel (Sensitive Barbels). 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 Duboisi Cichlid (Tropheus) and Flowerhorn Cichlid live together?

What size tank do Duboisi Cichlid (Tropheus) and Flowerhorn Cichlid 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 Flowerhorn Cichlid together?

Keep the aquarium between 26°C and 28°C. A target of around 27.0°C sits comfortably within both species' preferred ranges.

Are Duboisi Cichlid (Tropheus) or Flowerhorn Cichlid aggressive?

Duboisi Cichlid (Tropheus) is semi-aggressive (8/10) and Flowerhorn Cichlid is highly aggressive (10/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Duboisi Cichlid (Tropheus) and Flowerhorn Cichlid need?

Both species overlap in the 8–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

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.
