Weird snail on clam.

[SeanT]

I picked my crocea up to place it on a piece of shell...and I noticed this snail down near its foot.
Any ideas if this is a bad boy or not.
The body is shaped like a slug but the top half is definitely a shell.
He is banned to a baffle area right now until I get confirmation.
No need to kill an "Innocent until proven guilty" little fella'.

From the top and sides.

From on its back and side.

It looks like a Stomatella to me as well.
I have several in my tank, Stomatella's are great algae eaters.

Have you brought this to Dr. Ron's forum?
