I picked these up a couple of days ago. I really likes this small piece of Branched Tonga rock in a small display tank at LFS. They had just sort of tossed in in the tank with some peppermint shrimp and hermit crabs. I noticed it was covered with what looked like closed up Zoa's. I asked if they knew what they were and they said, "no, haven't ever seen them open up." So I got it cheap. Took it home, gave is a good iodine dip and placed it in some good flow and this is what opened. :thumbsup:
Anyway, can anyone ID these for me please?
