Turbo have a big problem righting themselves if they get knocked over
ontheir backs. Astra a dn cerith and nassarius and also the mexican
margaritta all do good at righting themselves. I quite buying turbos
for just this reason., Its a heck of a note seeing a snail updside
down in an inaccessible place in a tank unable to right
itself.......Astrea do just as good at what snails do as a turbo does
without the inherint problems turbos have.

I never had turbo snails, but Astrea are having problems on the sand.
Usually when they drop in the fine sand area with no rocks/rubble
nearby they are stuck and waiting for my magic stick to do the trick.

I always introduce new snails the way they are right side up on the
rocks - this way they at least have good start in the new place...

Turbo/astrea snails are living in the reef area where there is
no sand - every surface is hard around them. They did not need
to develop the ability to right themselves up. Compare to ceriths
or nassarius which naturally live in sand - they can do the trick.
