Assassian Snails
Do you have snails in your aquarium that you just can't get rid of? Then get the assassin snails who will get rid of all your problems. Now I know what you're thinking, "but then won't I just have more snails''? NO! These assassins will kill them all and don't reproduce nearly as fast so eventually when all the others are gone you can just pluck out the few that are in there. Usually costing about $5 each they can get pretty expensive. Which is where it gets even better. Here is some more info on the ones that we can sell to you.
Only $2 each which is more than 50% off!
You can buy it on craigslist which has all the info.
I live in Texas,USA!

This is a fact!! These snails might as well have ninja bandanas because they go straight to work annihilating the other puny snails in the tank. And what you said is true.. they spend more time hunting and killing than reproducing.. These assassin snails are real men!
