Coral Hitchhiker?

[Eaglepenguinz]

Hello,

I’ve recently gotten into the hobby of keeping marine fish instead of freshwater fish, and I’ve got some weird coral looking things growing from the live rock and I can’t seem to find out what they are.
Any help is appreciated, and first answer gets a cookie

thanks,

Its a tiny feather duster worm. Harmless but you can remove/kill it easily. They just sit there and filter feed.

Welcome to Reef2Reef! That is a harmless feather duster worm, super cool hitchhikers.
Keep safe and God bless you!
