ID Please

Would someone ID these little white barnacles looking things on base of coral. Dipped it in Koral md, didn't seem to have any effect. Seems to be inhabiting coral growth.

Looks like vernetid snails to me. They burrow into surfaces (harmless on rock, but can damage coral) and send out webs of mucus to help collect food which can also irritate corals. What kind of coral are they attached to?

Only on 3 arcos, but this one the worse. The pic is Northern Lights acro. What will kill them, koral md coral dip didn't seem to do anything. Thanks for any suggestions

Super glue the hole they come out of, or scrape the tube off at the base

Do little feather dusters or thread like strings come out of tubes?
