And found these:

Not exactly sure what you found on the glass, I do see algae and the small white dots are feather dusters. The ones coming out of the sand also appear to be feather dusters.

Interesting seeing them so far from live rock!

Ya they pop up every where

so they're able to live on the glass? or should I try to move them into the sand?

If its on the back glass I would leave them, I have some starting to grow on my glass and I don't mind. The viewing glass is different, I wipe them off the front and sides.
