Help with hitchhiker ID

[jldb97]

Hello,

I’m new to the hobby and have just got a new coral in my tank, I’ve noticed what looks like some kind of worm attached and wondered if anyone can help with ID? Can’t seem to find it anywhere, wanted to know if it’s something I need to worry about.

Thanks

Looks like a feather duster worm to me, harmless filter feeder. I think they're quite pretty!
