Can you identify this worm?

Hey Guys! I've noticed my tank has a lot of these worms under the rocks in the the sand. What are these? And are they good or bad for my tank?

Thanks!

Bristleworm. Usually good to have depending on its size.

dont touch them, they will sting you all joking aside.

if you have alot of them, it's a good indication that you are overfeeding.

+1, if they get too big, then you should remove them!

That's a bristleworm (as stated first by Dean). Again, they are good (if not too big). They are the sign of a healthy tank and add a good biodiversity to your system.
