Can Auratus Cichlid (Mbuna) and Silver Prochilodus Live Together?

Auratus Cichlid (Mbuna) is a highly aggressive species (9/10), while Silver Prochilodus is generally mild-mannered (4/10). This notable difference means Auratus Cichlid (Mbuna) may occasionally assert dominance over Silver Prochilodus.

Auratus Cichlid (Mbuna) and Silver Prochilodus 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: Silver Prochilodus is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 23°C and 28°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

The pH requirements of Auratus Cichlid (Mbuna) (7.6–8.6) and Silver Prochilodus (5.5–7.5) 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.

To house Auratus Cichlid (Mbuna) and Silver Prochilodus together, plan for an aquarium of at least 450 litres with a minimum length of 150 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), Established Algae (Otocinclus). 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.

Auratus Cichlid (Mbuna) and Silver Prochilodus are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.
