worm like bugs in my live rock?

[drummerj]

hi everyone! Im kinda curious about these little wormy like bugs all over my live rock. theyre pretty small, maybe no more than a quarter of an inch, they have a bunch of little legs and are light gray or white and move very fast. Can anyone tell me what they are?

Thanks!

in any event, are they bad?

They are beneficial and a food source for some of your critters.
