What is this?

I was wondering what this is in my tank. It looks like very long brownish strands/strings coming out of my live rock. It’s kind of hard to see in the picture below, but I did my best. I tried to circle where it is. Thanks for any help.

Spaghetti worm, harmless. I also see vermited snails in the bottom left and top right as well as bubble algae in the bottom left. Those, not so harmless.
