Vermetid Snails Hitchhiking on Snails

[Spartanwarrior]

Hey All,

So I've been slowly chopping off all the Vermetid snails I find on rocks, frags etc as I see them, but noticed a lot of my Astrea snails have them attached as hitchhikers. Should I also chop them off these too? How quickly do they spread/reproduce? i'm guessing this could be the way they've been spreading around the tank in the first place...
