picked up a piece of rock with some mushrooms on it, this one was sort of hanging off the back side and i have no idea what it is. the picture really doesn't do it justice, the little "bubbles" are florescent orange, very pretty! it's about 1.5" across. it was blowing around in the flow so i attached it with a little glue so a small piece of dead coral that had a "dent" in it, sort of like a little nest.
