New Astraea Snails Not Moving...

[Myka]

Try putting them on the rocks instead of the sand, they don't like being in the sand much, and won't go there very often on their own accord.

Thanks for the input!
The hermits I have are tiny so I don't think the snails are in danger quite yet. They are on rocks right now, but I thought maybe I would try different rocks, or maybe I should just leave them alone... Not sure.
