Mantis or Kool Algae?

[Siderjan]

I was looking at my tank last night with a flashlight and saw something either coming from under a rock or growing on the rock that looked like the picture below.  Tonight I looked in the same spot with the lights on, and my LED flashlight but it was gone.  Any suggestion what it might be?  Sorry I'm not an artist and at 1:30am didn't want to wake the wife up getting the camera.

I like your daughter's tastes.  I'm gonna have to get my Grandma to knit me some mittens that look like that.
