Strange "things" in my tank.

I can't get a good picture of them but there are prob. 10-20 of them now. They are small clusters of tentacles. The tentacles are green/yellow, segmented and hair thin. They are only about an inch across. The base is only about 1/8 of an inch round, fuzzy, and orange with the tentacles coming from it. They also seem to move around the tank. I have asked around and no one knows what I'm talking about. What the hell are they and are they dangerous. I suck them out with a syringe whenever I see them but they seem to reproduce rapidly. All my coral seems to be doing well and multiplying but I'm worried these "things" will take over. Maybe some sort of anemone?

 

It's way to small to tell anything from that pic, can you try and get closer? Doesn't look or sound like aiptasia, but again it's hard to see.

 

Spaghetti worm.....I had posted on it already. I have one sticking out of my sand right now. Let me take a pic and post it to see if it's the same thing.

 

They are very small

 

Here is the pic of the one in my tank. They are good guys. Mine buried itself right on the bottom edge right where the glass is.


Here is a link that Cannedmulder had sent to me on my post.
Spaghetti worms utilize tentacles in amazing ways

 

Yeah thats it. Thanks.

 

Glad I could be of use!
