Im not exactly sure what this is. It came on a rock i got. The guy said he had seen in for a long time, but it never did anything. Since i have put it in my tank, its been opening and growing, and another one has sprouted up right next to it as well. Guess it pays to have decent lighting. lol

I know the pix are horrible, had my sister take them really quick. If better pics are needed let me know.

Any idea what this is?
Thanks
