strange worms (?) in my tank...

Well, I'm not exaclty sure, what I got there. I don't think it is bad, but I thought I'd ask...

I guess it is a worm, but I don't see the body. Some of them are in holes in rocks, others are kinda building tunnels by collecting aragonite pieces and somehow "glueing" them together to a tube on one of the rocks. The only thing I see of them is their arms. And they got lots of them. Maybe 20? I can't count. They seem completely independent from another, and they are long, probably about 3 or 4 inches. About as thick as the antennas of my CBS buch much more soft and flexible. They move pretty fast, looks like they are looking for food (well, what else could they do anyway). And they are white with some darker spots or stripes on them.
I tried to take a picture of them, but can't get anything together.

 

I don't know the scientific name, but I' have had then in my tank for over two years with no adverse effects. The vast majority of polycheates, worms, are harmless or beneficial to your tank.

 

I think they r called peanut worms

 

Thanks Bruce!

well, so much about 4 inch arms... I think, 10 inches fits better. Amazing.

But my shrimp don't seem to care, they sit in a cave right next to a really big worm, with the arms of that thing all around them.

 

Are they spaghetti worms?

 

I don't know, the "arms" are pretty thick. thicker than I thaught at first. Maybe like those very thin spagetties ...
well, the name would fit

 

well, I just found a pic, I think that's, what it is. strange little things

 

Thin spaghetti, like angel hair?  [smiley=clown.gif]

I know there are some good pics or links on the board somewhere. I had to dig back 227 days to find that one though.

They are definitely strange.
