Multiple hitchhikers needing ID

[EchoRomeo]

Have 2 protrusions sticking out of scoly that I just bought and dipped. Also a threadlike worm protruding from under the base of my acan. Please help identify and let me know if they'll cause any issues.

3rd picture is a chiton. I don’t really see anything else in the other pictures.

The scoly has 2 protrusions in the center that disappear when I get close and the acan I circled in red have a threadlike protrusion.

I added a video to be more clear.

The scoly protrusion looks like a vermitid snail. And I’m not to sure what the other thing is. It kind of looks like a spaghetti worm but it’s a little different.

It looks like spionid worms on the scoly, and branching hydroids for the white string like ****heads.
