Assassin Snail (Clea helena) 0.5-1″ for Sale in Canada

The Assassin Snail (Clea helena) is one of the most popular freshwater aquarium snails for controlling unwanted pest snail populations naturally. Known for its attractive yellow and dark brown spiral shell pattern, this small but effective predator snail helps aquarists manage overpopulation of nuisance snails while adding unique beauty to freshwater aquariums.

Unlike many aquarium snails that reproduce quickly, Assassin Snails are carnivorous snails that feed primarily on other snails, leftover food, and organic debris. Their peaceful nature toward fish and shrimp makes them a valuable addition to many community aquariums.

Monster Aquarium Canada proudly offers healthy Assassin Snails (Clea helena) 0.5–1 inch with professional live aquatic animal shipping throughout Canada.
