How to move a Clam? for future references.

[Douglas]

I tried to move my clam yesterday, due to an anenome moving to close. I have no sand, so it was just attached to the glass on the bottom. It spun around once, and unattached, but the next day it had died. I don't think that was a proper way to move it. I'm looking for advice, for future references, to move a clam, with out killing it. Thanks, Doug
