Few questions here.

I have posted here before and was in need of help again. I have a 20 gallon saltwater tank. In the tank is 3 pieces of live rock, a few crabs, a horseshoe crab, 2 damsels, a tomato clown, rosebud anemone, a wrasse, and a foxface. The past few days I have noticed something in my sand. It looks like worms almost. They are in patches and are light green with dots on them. They move like worms would. Also I have a wierd looking algea on my rock. It almost looks like mold. Any ideas? Should I be concerned? Any cures? Thanks.

Ok. It is some sort of worm. I pulled one out. It is a dark body with long hairy looking strands on it. Any ideas?

A pic would help for a positive id.

Sorry. the pics are large, but I wanted to show the problem. The hair looking things are the worms. The last pic is a bit of the moldy looking substance on the rock.

I can pull one out of the sand. I was just in a hurry this morning. Let me know if I need to. I will post a pic of one out of the sand. I can't find anything on this. I have searched the web for worms and parasites. Nothing matches this image. There are about 6 in the tank.

Ok I had someone on another site say they were spaghetti worms. They did not say if they were bad or good. I have no idea what to do. Would you leave them?

[saltjunkie]

that person is correct.. and they are good to keep around....
they just further the breakdown process...
big food is eaten by big fish..
then broken down further and further....

very simple explanation, but im not a scientist or anything..

bottom line..
they are good to have.. keep emm..
