Stricks wrote What's strange is that I started my pond last September, and no
signs of
them whatsoever until about two weeks ago (and no new plants either). Where
did they come from?

I've never been able to keep snails with koi.
They ate them. But they survived in the filter.

They probably came in as eggs on plants when you put your pond together last
September and wintered over as eggs hatching out in the warm weather.
