worms? are they bad?

[mr.sneakysnacky]

So I have worms in my sand and I know this because I can see them... through the glass... but are these bad things? and I also have bristleworms living in my live rocks as well so I was wondering if bristle worms were bad things too?

all the information i can get will help! thanks

The worms in the sand probably good, but we need a better description. What do they look like? I think bristle worms r good, as long as they r not at plague numbers. But that would probably be caused by another problem, like over feeding. They r good detrivores, but can cause irritation if you touch them when moving rock around.

They are not bad for your tank, but not the prettiest inhabitants of your tank. If I see one in my tank he's a goner. Creepy little buggers are not welcome in my tank
