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!

If it helps at all, I *think* the common Pond Snail that circulates around the aquarium trade is Lymnaea/Radix peregra.
 
Thanks, vampie! I saw peregra mentioned in a few places and some of the photos were a pretty good match, but some weren't. It seemed that a couple of different kinds of snails were getting labeled with that species name and I wasn't sure who to trust. If that's the most common one, that's probably what I have though. They were hitchhikers along with the bladder snails.
 
Common Pond Snail....

They should reproduce just fine but not as quick as the bladder snails so just give them time.
 
Yeah, I'm thinking peregra too.
It definitely doesn't look like the ones I have, which makes me even more inclined to thing I may have l. stagnalis.
 
I found a third one this morning, larger than the other two, so I'm hopeful that they are indeed breeding.

EDIT: Should have said "smaller than the other two." Doh!

Congrats! Do keeps us posted on those. :)

No clue on the sci name I'm still looking, but as you found it seems to be a jumbled mess as to what is what.
