Thank you all for your advice. I'm not certain of the method I'll use yet. I think, since I can't get a fish that will eat these guys, I'll just throw them out, bleach and rinse the tank really well, and sell it. My poor heart. I just feel bad killing the snails. But it is just a tank full of snails and I don't want it anymore.
I'm still looking for someone near me who has a snail problem, I want a bunch to start a breeding colony to feed my turtles. Throw some in a plastic bottle and mail it to me
