I use common pond snails instead of ramshorn snails because the latter grow large enough that I think ingestion might produce an impaction. But the common pond snails stay fairly small. Also, they are hermaphrodites and reproduce prolifically, so if a few get eaten it's not a big deal. And if you have too many, floating some prewashed organic romaine lettuce or spinach attracts them and you can just pull them out in a bunch. My tanks are planted and the snails seem to be attracted only to grasses.
I read somewhere, i think on the Caudata.org forums, and have heard from friends, that ghost shrimp are handy because when more than just a few individuals are added, some invariably manage to escape being eaten by the tank captives.
