I just got live rock and live sand today... now... can anyone tell me what the heck this is? It's very hard to get a good pic, sorry... basically, it looks like a couple of brown, dead leaves about 1" long that were stuck on the rock, but they are definitely growing out of it. I haven't seen anything that looks like it, so if anyone could tell me what it is I would be appreciative for curiosity's sake.
