Assassin Snail (Clea helena) - Small/Medium

Clea helena is a snail that eats other snails, which makes it one of the few truly effective biological solutions to a pest snail bloom instead of just another mouth competing for the same algae. It hunts by tracking scent trails through the substrate and will happily take down snails several times its own size given enough patience.

Care level: Easy · Temperament: Semi-aggressive to other snails · Max size: ~1" · Min tank: 10 gal · Diet: Carnivore, snails + sinking meaty foods
