What is this snail?

[callisto9]

I'm used to see ramshorns, pond and MT freeloader snails on plants, but this is the first time I've seen this snail.

I've found three of them so far and they are about the size of a pea or smaller right now. Looks like an assassin snail to me, but not sure. Coloring is brown and offwhite/yellow. White snail bits with a little siphon of sorts.

Any ideas?

That's an Assassin snail.

OK, cool. That's what I though. Surprised to see them as freeloader snails!
