Baby snails - special care?

[OCSREEFER]

I posted a thread about possible snail eggs a few day ago..
since then I have found this little guy moving around trying no the become lunch, for my crabs.

I about five different types of snails
Nassarius vibex snail
star snails
nerite snails
cerith snails
turbo (astrae) snails

Not really sure what type this is, or is there something special I should do to help its chances. Its hard tell by the picts but its only about 3mm across...

It has moved about 5 inchs along the sand since Saturday night..
What do you all think???

Thanks
Nick
