What are these white & black worm-like things?

Have had these in my tank for a little while now and haven't been able to figure out what they are for sure. They're white and black stripped and like to collect around this coral and I'm not sure if they're benign or something I should be removing.

Here's an image, please ignore the turf algae explosion:

Possibly a spaghetti worm (taxonomic family Terebellidae) - I'm not entirely sure though.

I agree with spaghetti worms…harmless detritus feeders.
