Can Chisumulu Pearl Cichlid and Ninja Shrimp Live Together?

Chisumulu Pearl Cichlid is a moderately assertive species (6/10), while Ninja Shrimp is peaceful (0/10). This notable difference means Chisumulu Pearl Cichlid may occasionally assert dominance over Ninja Shrimp.

Large aggression gap (6 points) between Chisumulu Pearl Cichlid and Ninja Shrimp increases stress risk for the more peaceful fish.

Chisumulu Pearl Cichlid and Ninja Shrimp 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.

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 Chisumulu Pearl Cichlid (7.6–8.6) and Ninja Shrimp (6.5–7.5) 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 Chisumulu Pearl Cichlid and Ninja Shrimp together, plan for an aquarium of at least 140 litres with a minimum length of 90 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), Plants - Densely covered, Leaf Litter/Blackwater, Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Chisumulu Pearl Cichlid is a plant destroyer, which conflicts with Ninja Shrimp'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.

Chisumulu Pearl Cichlid and Ninja 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.
