Snail IDs

These little snails showed up the last 2 weeks. They are white in color and all over the place. On the rock and glass. I have a couple clams and Im getting a little worried if these could hurt them. Any Ideas? The pic acually shows 2 that are stuck together. They are not even 1/8" across so hard to get a real good pic. Any ideas?

Lets try again. Here is a pic. (hopefully)

 

Another snail I caught scaling the glass tonight. ???

 

Those are Tropical Abalones. Some people will call them stomatellas which are similar, but I have those exact ones and black ones, and have been positivly ID'd by 2 marine biologists as Tropical Abalones. The link is to a abalone fishery in Tasmania.

Sheeeesh! Here is another one never seen before. This stuff is coming out of nowhere! I think this is a Stomatella Varia but not sure. Any ideas?

 

Im sorry. Its late and Im bushed. Here is that Stomatella. I think.

 

EDIT:ya keep adding pics while Im typing, lol....

The first pic is a abalone, 2/3 is a stomatella, 4th pic is abalone.

 

both are beneficial, algae eaters.

 

lol. Im sorry. My brain and fingers are not attatched at this time of night. Thank you so much for the IDs.

 

You are thinking about the pyramid snail they look like little tiny pointed ice cream cones LOL cream to tan to light brown in color .. I did every clam we have up front before then enter out tanks.. I dipped clams daily at work until I get them under control last winter. I got 130 + from just one clam in a 10 mi test vial it was almost full of them..Set your clams on flat rock or old clam shells to help them ward off
