Can Bee Shrimp (Crystal Red / Black) and Trapdoor Snail Live Together?

Both Bee Shrimp (Crystal Red / Black) and Trapdoor Snail are peaceful species with an aggression score of 0/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.

Bee Shrimp (Crystal Red / Black) and Trapdoor Snail 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.

Worth noting: Trapdoor Snail is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

The safe temperature window for both species falls between 18°C and 24°C. Aim for the midpoint of this range (around 21.0°C) for optimal comfort.

The pH requirements of Bee Shrimp (Crystal Red / Black) (5.5–6.8) and Trapdoor Snail (7–8.5) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Bee Shrimp (Crystal Red / Black) needs 3–6 dGH while Trapdoor Snail requires 8–20 dGH.

To house Bee Shrimp (Crystal Red / Black) and Trapdoor Snail together, plan for an aquarium of at least 38 litres with a minimum length of 40 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: Soil / Nutrient Rich, Plants - Densely covered, Driftwood (Digestion/Hiding), Leaf Litter/Blackwater, Established Algae (Otocinclus), Sand (Sifters). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Bee Shrimp (Crystal Red / Black) requires Soil / Nutrient Rich, while Trapdoor Snail requires Sand (Sifters). These substrate types may be difficult to provide simultaneously. Compromise where possible or prioritise the more critical need.

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

Bee Shrimp (Crystal Red / Black) and Trapdoor Snail 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.
