Uniidentified pest?

I have these little pointed things on my rock and on some coral frags. Anybody know what they are?

vermetid snails, they can be annoying. They emit a slime that catches food and they suck it back in to eat it

They don't really harm anything. You can use wire clippers to grab them and pull them out

They can irritate corals, especially zoas. I remove them. Careful breaking them off, they can be sharp.
