Help ID a large snail

[Andy]

not sure what it is. i found 3 of these guys and took them home. they look like oversized snails with their meaty body overflowing their small shells (but when they retract they fit in the shell). Here are a couple of photos IMG-20111209-00192 | Flickr - Photo Sharing! and large snail abalone | Flickr - Photo Sharing! are they abalone? can you put them in your reef? thanks!

Hmmm, no idea from me. Pretty cool looking though. If you could take it out and get some close ups of it, might help.

Where did you find them?

I believe that they are Swollen Bubble Snails, family Hydatina
