The Assassin Snail ($\text{Clea helena}$) is the natural, chemical-free solution for controlling pest snail populations (like Ramshorn, Bladder, and Trumpet snails) in your freshwater aquarium. Unlike most snails, the Assassin Snail is carnivorous and will actively hunt and consume smaller snails, helping to bring infestations under control. They are also highly attractive, featuring a distinct yellow and black banded shell. While they are great pest control, they are safe for all fish, shrimp, and healthy plants. They will also scavenge leftover fish food. Price: $200\text{ Tk}$ per pair snail.
