tiny little worms...are they bad?

[Evil McToast]

I was looking very closely at my rocks when I noticed a few tiny little worms wiggling around. At first I thought they were pieces of hair algae blowing in the current, but then I saw them move a short distance. They are about 3/4" long and very skinny. They are a light shade of brown and move like caterpillers. Should I be worried?

Nope....no worries.....sounds like little bristleworms. they eat detritus and dont harm any corals unless they have died or have dead stuff on them.
