Unidentified wormy object

So for a while I have noticed this skinny long gray worm that loves in this like cave and at his mouth he had what looks kinda like a polyp, he is smooth and Grey video attacheshttps://vimeo.com/162007154

Also a long time ago I found this weird anemone and some people said it might be a Mojano but I don't think it is tbh it looks nothing like a Mojano, and in a year it hasn't moved or multiplied at all

That looks like a harmless peanut worm in the video. I'm not really sure about that anemone looking thing though.

That is definantly a peanut worm thanks for the id, and the anemone really has me stumped the Rock was Fiji premium and I tried researching all anemones native to Fiji and nothing came up that looked close to what I've got, is t possible it isn't an anemone or maybe something rare?

I looked up the peanut worm and it says they may bore into rock to make a home, I think I have at least two of these worms so if they reproduce could this be a problem if a bunch of them bore into my rock

Nah. Live rock is full of holes anyway, the holes increase the surface area and are part of the reason why it's live. There's no way peanut worms could cause structural problems unless you had dozens of adults on every piece of rock, and you'd have to have an immense amount of food just lying around for that many worms to grow up. As long as you don't overfeed to a ridiculous extreme, you're fine.
