Can Checkerboard Cichlid and Rummynose Rasbora Live Together?

Checkerboard Cichlid is a generally mild-mannered species (3/10), while Rummynose Rasbora is peaceful (2/10). This modest difference means Checkerboard Cichlid may occasionally assert dominance over Rummynose Rasbora.

Checkerboard Cichlid and Rummynose Rasbora both frequent the 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.

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion.

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 Checkerboard Cichlid (4.5–6.5) and Rummynose Rasbora (7.3–8.5) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Checkerboard Cichlid needs 1–5 dGH while Rummynose Rasbora requires 10–20 dGH.

To house Checkerboard Cichlid and Rummynose Rasbora together, plan for an aquarium of at least 60 litres with a minimum length of 60 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), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Plants - Densely covered. Meeting these requirements will help both species thrive.

Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

Checkerboard Cichlid and Rummynose Rasbora 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.
