Tiny white baby snail things?

[Cantareadio]

What are these and are they safe? There are three that I can see. I dont know of they're hitch hikers (haven't gotten LR since November) or babies of my snails...
Just want to be sure they're safe for my tank

They are fine. I can't tell from the pic exactly what kind they are, but I don't know of any harmful snails that are white with round shells. Generally, if they were a problem, they would be on whatever is threatened by them- another snail, a clam, coral...Snails on the glass tell me they are algae eaters.

Great! Thanks!
I wonder if they're hitch hikers or if my snails made babies...if so then they're probably turbo snails.
Very exciting
Thanks Doug!
