Overview
What to know before you buy.
Known for their conical, bumblebee-striped shells, Assassin Snails are prized for their ability to control populations of pest snails. They are carnivorous and will hunt down other snails, but will also eat leftover meaty foods. They are slow breeders and a natural, effective solution for snail infestations.
Key traits
Care guide
Keeping Assassin Snail healthy in a South African setup.
Tank setup
Add it only to a fully cycled, mature tank: invertebrates tolerate ammonia and nitrite far worse than fish. Keep a lid on: many snails climb out.
Water parameters
Keep pH 6.5–7.5 and 22–27°C. Never use copper: most fish medications and some plant fertilisers contain it and it kills invertebrates. Drip-acclimate over at least an hour. Enough calcium and hardness keeps shells from pitting.
Feeding
Carnivore. Remove uneaten food within a few hours so it doesn't foul the water.
Behaviour
Most activity happens at night and around feeding.
Tankmates
Many fish eat snails (loaches and puffers in particular). Keep it with small, peaceful fish, or on its own.
Breeding
Assassin Snail breeds readily in a stable, predator-free tank.
