Help with hitchhiker ID

[jldb97]

Hello, I am quite new to the hobby and I’ve added another coral to my tank and I’ve noticed what looks like a worm attached to it. I can’t seem to find what it is, and wanted to know if it’s something I need to worry about. If someone could help ID?
Thanks

I think that’s a feather duster

+1 on feather duster, they are harmless filter feeders and are pretty cool to look at.
