Can Assassin Snail and Checkerboard Cichlid Live Together?

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

Assassin Snail and Checkerboard Cichlid both frequent the 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 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

The pH requirements of Assassin Snail (7–8) and Checkerboard Cichlid (4.5–6.5) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Assassin Snail needs 8–15 dGH while Checkerboard Cichlid requires 1–5 dGH.

To house Assassin Snail and Checkerboard Cichlid 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.

Assassin Snail and Checkerboard Cichlid 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.
