Funny, someone posted that they have an algae problem but doesn't want snails b/c the don't like them! Aw!
I'm feeling terrible b/c my girls ate the baby snails I got for them. I guess it's better than a slow death in a dirty tank, but now I know: if I want (free) pond snails, I have to put them in a different tank and let them grow up. I happen to like pond snails b/c they're relatively small, so there's less of a bioload concern, and their egg clutches can make good fish food if you don't need 100 baby snails...
I used to pull mature pond snails from our fish pond. They don't have the long, yummy anntenae for munching.
