Can Duboisi Cichlid (Tropheus) and Pictus Catfish Live Together?

Duboisi Cichlid (Tropheus) is a semi-aggressive species (8/10), while Pictus Catfish is generally mild-mannered (4/10). This notable difference means Duboisi Cichlid (Tropheus) may occasionally assert dominance over Pictus Catfish.

Duboisi Cichlid (Tropheus) and Pictus Catfish 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.

Worth noting: Pictus Catfish is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

The safe temperature window for both species falls between 24°C and 26°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

The pH requirements of Duboisi Cichlid (Tropheus) (8–9) and Pictus Catfish (6–7.5) 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.

To house Duboisi Cichlid (Tropheus) and Pictus Catfish 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). 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.
