⚔️ Assassin Snail (Clea helena)
Size: 1-1.5cm
The Assassin Snail is the most effective and natural solution for controlling nuisance snail populations in freshwater aquariums. Unlike other snails, Clea helena is carnivorous, feeding on pest species such as bladder snails, ramshorn snails, and pond snails — making it highly valued in planted tanks, shrimp colonies, and established aquascapes.
With its distinct yellow-and-brown banded shell, this snail is not only functional but also visually appealing. Calm, efficient, and purposeful, the Assassin Snail makes a powerful addition to tanks that need balance and cleanup support.
