Species Overview
Assassin snails (Clea helena) are beneficial molluscs used to control pest snails in aquariums. Their conical shells sport yellow bands with dark stripes, adding subtle appeal.
Tank Requirements
- Aquarium: A group of three can thrive in a 10‑gallon tank. Provide sandy substrate for burrowing.
- Water: Keep temperatures of 68–80 °F and a pH of 7.0–8.0. Ensure good oxygenation and gentle flow.
Diet and Behaviour
Unlike many snails, assassin snails are carnivores. They hunt pest snails like ramshorns and bladder snails. Supplement their diet with sinking pellets, bloodworms or fish food when pest numbers are low. They bury themselves by day and emerge at night to hunt.
Assassin snails coexist with most community fish but may eat small shrimp. Use them in heavily planted tanks to prevent algae outbreaks. Incorporating live plants for fish tanks provides hiding places and enhances water quality, creating an attractive environment where these miniature predators can work effectively.
