be sure to rinse and inspect them as well, even before inserting them in a fishless tank, unless you want pond snails. rinse them under warm water and then feel every stem and leaf with your fingertips for anything that feels like jelly or snot. these will be pond snail egg clusters, and if they get in your tank they stand a chance of quickly overrunning it and driving your bioload through the roof.
So remember, when you're feeling very small and insecure,
How amazingly unlikely is your birth,
And pray that there's intelligent life somewhere up in space,
'Cause there's bugger-all down here on Earth.
