What is It?

[sandy]

Okay, I already checked the hitchhiker id link that I have. I have what I thought was a baby bristle worm... but now I'm pretty certain it is not. There are two...
Bright red, string/worm like things, very small but growing. One is on the glass on the back of the tank (just on the glass, not attached to rock), the other is between the glass and the sand (below the sand) with thread like parts reaching for the surface (for food I guess). The one on the back of the tank is growing thread-like arms.
What are they?

Hopefully this is not one of the questions you have answered more than 1000 times. If so, please indulge me with a link or something. Tanks.

Thanks Sammy. I don't have a camera that good! Threads all over the body. Well not really a 'body'. The more I look at it, the more it looks like a bunch of teeny weeny branches on a tree. I'll watch it. At first I thought it was a molted leg of a pepperment shrimp clinging to the glass... But it changed shape. It is red.
The other one may be sp. worm or hair worm. Are they red?
