Not sure if Nudibranch or Stomatella, or something esle

I found a couple of these guys in my glass.  Been doing a bit of research and I'm not sure if Nudibranch, stomatella , or something else.

Could it be baby astrea?  Very tiny and pick was with camera zoomed al the way.  I have spotted about 4.  they seem to like the glass.

 

Any ideas would be appreciated!

Need to see the shell to determine what kind of snail.  Can you get a top and side shot? Defintely not a nudi.

Doesn't look like either, the stomatella always have a fleshy foot the extends past their half shell.  Could it be a colonista snail?

I think you are right, Well done Granite Reefer.  

 

Here is a better pic.  It matches well with pics from internet.
