What are these things?

[armywife022]

Hi everyone. Can someone tell me what these things are in my mantis tank?

I find it rather hard to describe them, but they are tiny, about an 1/8" and they are all over. On the rock, the glass, just everywhere. They almost look like little tube worms but I don't really see a feather.

I cant remember what they are called but I do know that they are a sign of a healthy tank, I had them real bad and hated it. Finally they jus up and left after about 6 months
