Assassin Snail (Clea helena)
Assassin Snail (Clea helena) are very easy to care for. Its not as easy as caring for some other types of snails, but as long as water conditions are right, and food is plentiful, Assassin Snail care does not take much effort. The keys are tank size and stability. When adding new Assassin Snails to a tank, do so slowly and gently. Try to make sure the display tank water in the plastic bag matches the new tank water parameters as closely as possible.
WARNING: They hunt and kill other snails!

McMerwe Review: These are some of our favorite snails! Not only can they keep your unwanted snail population in check, but they look fantastic and breed very slow. They are the best way to get rid of other snails. We don’t like adding chemicals to the water to kill pest snails, as the pest snails usually die with a day or two. This will result in an ammonia spike in the water. This ammonia spike might kill your other livestock as well. Therefore Assassin Snails are the more natural and slow way to kill unwanted snails.THEY DO NOT HUNT SHRIMP. They might kill/eat weak or dead shrimp, but in our experience they are perfectly shrimp compatible.

I bought 2 Assassin Snails. They have already started to get rid of the unwanted guests in my tank.

Love these snails! They quietly go about the business and clean up anything in the aquarium! I throw in ramshorn snails to see how fast they get to work! 5 snails take out atleast 50 snails in one week

Can wait to see my Assassin go. Came very well packed. expected it to be a bit bigger, but not the end of the world. Gives more time to see them grow up. Currently feeding mine small pieces of beef while I am waiting for my MTS to grow up so I can add them.

The prettiest snail I own, and also the least troublesome. Beware to not keep these guys with any other ornamental snails that you want to keep
