ID Please?

[fireman26m]

Just setup the tank a few days ago. Have a few hitchhikers popping up. This one's ID eludes me. At first I thought flatworm when I saw one on the glass. But seeing them on the rock they have more of a grub shape. They are 1/4" long, white-gray with a gray stripe along the side. No protuberaces (ie. antennae, siphon). They have no shell that I can see, however, each has what looks like a small bundle of rock or algae on its back. This is the best pic I could get. Thanks in advance.

Update. I touched one and it has a hard smooth, rounded shell but seems to be covered by it's mantle. The rock/algae was exactly that. It fell off once I touched it. Baby Cowrie's maybe?

Got a much clearer pic of one of the little critters.

It doesn't look like a cowrie, maybe a snail or limpet. It is still hard to tell by the pic. Possibly a top crown snail....

Stomatella is my guess

 

[roka64]

That might be a good guess Allen.
Does the bottom have a line running up the middle, like two separate "feet"?

 

[fireman26m]

No line. Solid white bottom.

It's hard to tell, how about anything on this site:

Ok....I'm pretty sure it's a Stomatella after looking at more pics of them. Good call Ziggy!

+1 on Stomatella Varia. I had one that rode in on my LR and now, 4 months later, I have about 8 of the little buggers. They seem to move fast and eat slow!! Very beneficial to my system!!
