Snails for "pet" blueys is always a debate. Inverts make up most of a wild bluey's diet, but they also carry many parasites that may/may not be passed on to your pet that is not used to eating them.

If you can guarantee their origin and cleanliness by isolating them before feeding, I say go for it.
