Are we talking about sand bottom tanks ?
Because I would disagree with you then...

I have seen astrea snails being stuck on sand
turned upside down and not being able to
grasp anything hard in nearby to get leverage.

What is REALL hilarious is wathcing an astrea try to climb on something
that is lighter than itself. I once watch an astrea try to climb on top
of a nori clip that had come loose and fallen to the bottom of the tank.
Every time he'd start to creep over the edge to get on top, it'd flip
over (since he waieghed more). The persistent little mollusk kept at it
for a good 20 mins before *I* gave up wathing.



If you have sandy bottom in your tank never
just drop snails - place them on the rocks right
side up and watch them until they can walk...
I see many snails being stuck on the sand.

Depends on the smail type. Ceriths have no issue going on sand.
