can anyone point me in the right direction in identifying this:

Sorry the picture isn't better, my D70 is in the shop for repair.

We found this little guy on a piece of Tonga rock we got from one of the LFS sump rubble buckets. he is about 1mm in size, has a translucent pinkish center and little tiny arm extensions with little white tips to them. doesn't look anything like a glass anemone, but with all the different possible subspecies, who knows. this little guy looks more like a small zoo polyp or even a really small mushroom, but again, its so small i dont' know.

Anyone have anything like this in their tank?
