Anentome helena — Assassin Snail

The Assassin Snail is a predatory freshwater snail with a striking cone-shaped shell banded in yellow and brown. It actively hunts pest snails such as Malaysian trumpet snails and bladder snails, making it a popular biological control agent. Native to Southeast Asian rivers, it is peaceful toward fish and shrimp but will methodically reduce unwanted snail populations.
