Watch were you buy snails

[PSH]

Or you may have snails on your snails.

Astraea snail with Pyramid snail:

and sine astrea snails are colder water snails, we should probably be avoiding them all together..
but that said, good advice and another reason to QT everything you get..

[saxman]

nice pic! nasty little vampires...

whenever you buy snails, particularly Astrea and turbos, you should inspect them with a mag. glass and give them a scrub with a soft toothbrush and a good swish in SW before the QT begins.
