I have a bunch of regular bladder snails, but lately I noticed that some of them looked decidedly bigger. I investigated more closely and found two that are definitely NOT bladder snails, and I grabbed a few snapshots of one of them. Based on the "donkey ears" and the right-spiraling shells, I'm guessing they're some kind of pond snail (Lymnaea), but they don't look like Great Pond Snails (Lymnaea stagnalis) and I can't seem to find much info on other kinds. Ideas?
I think they're cute and they don't seem to be eating my plants, so I'd like more of them. They're definitely way outnumbered by the bladder snails and I can't find any babies of this type. Do I need to do anything special to encourage them to get busy?
Thanks!
