Assassin Snails — Nature's Pest Snail Control Assassin Snails (Clea helena) are the natural, chemical-free solution to pest snail infestations. With their striking yellow-and-brown striped shells, they actively hunt and consume bladder snails, ramshorn snails, Malaysian trumpet snails, and other small pest species — restoring balance to overrun aquariums. Once pest populations are under control, they switch to scavenging leftover food and detritus, never harming live plants or your fish. Care Guide Tank size: 10 gallons or larger; group of 3–6 for effective pest control Water parameters: Temp 75–80°F, pH 7.0–8.0, GH 8–18 (hard water supports shell health) Diet: Carnivore — pest snails are their preferred food. Once pests are gone, supplement with sinking pellets, bloodworms, and high-protein foods Tankmates: Safe with most community fish and live plants. Not safe with shrimp fry or other ornamental snails (mystery, nerite, ramshorn) — they will hunt them too Why Choose Our Assassin Snails Active hunters — ready to clear out pest snail populations Live arrival guarantee with fast US shipping Heat or cold packs included as needed
