Can Peacock Cichlid (Aulonocara) and Red Tupfel Shrimp Live Together?

Peacock Cichlid (Aulonocara) is a moderately assertive species (6/10), while Red Tupfel Shrimp is peaceful (0/10). This notable difference means Peacock Cichlid (Aulonocara) may occasionally assert dominance over Red Tupfel Shrimp.

Large aggression gap (6 points) between Peacock Cichlid (Aulonocara) and Red Tupfel Shrimp increases stress risk for the more peaceful fish.

Peacock Cichlid (Aulonocara) and Red Tupfel Shrimp both frequent the Bottom (Substrate) and 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.

The safe temperature window for both species falls between 24°C and 25°C. Aim for the midpoint of this range (around 24.5°C) for optimal comfort.

The pH requirements of Peacock Cichlid (Aulonocara) (7.8–8.6) and Red Tupfel Shrimp (6–7.5) do not overlap, making it impossible to satisfy both species simultaneously.

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

To house Peacock Cichlid (Aulonocara) and Red Tupfel Shrimp together, plan for an aquarium of at least 200 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), Smooth Gravel (Sensitive Barbels), Established Algae (Otocinclus), Plants - Densely covered, Leaf Litter/Blackwater. 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.

Peacock Cichlid (Aulonocara) and Red Tupfel Shrimp 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.
