Hitch hiker on snails

[One Fish]

I found these on 2 snails in my invert QT. Might be vermetid snails, but not sure. I also have 6 coral frags in this tank, 20 days into my 76 day quarantine.

what do you think they are?

any advice for preventing them from getting into my DT?

thanks!

they’re verment snails, I recommend u to take it off they irritate corals and can even kill them.
