1/4" Size Snail ID

[Fort Salty]

The snail in question is riding on the left side of the Astrea. I first noticed it twice after dark on the sand bed a week or two ago. I figured it was eating detritus/food like a Nassarius, but I'm not sure now seeing it ride another snail. Your help identifying is much appreciated.

From other similar looking snail ids I’ve seen. Possibly a dove snail?

@WheatToast might know.

Thank you very much! It looks just like the pictures of Lightning Dove snails I am seeing online.
