Ok I just noticed this on a rock with one of my mushrooms.

I'm not sure how long it's been on there, just noticed it now. It doesn't seem to move but looks like a coral of some sort. Just dark with little spikes
 
Cool specimen! Try not to take it out of the water or it could harm it. Some sponges can die pretty easily when exposed to air. I'm a little jealous. Never ran across that sponge in 15 my years.
