I bought a new frag today at LFS. It was labled as flowerpot coral or goni. I picked it up and once I dipped and acclimated it to the tank noticed something comming out. It looks like a white hand similar to a feather duster but not the same. Please let me know what it is and if i need to do anything. The goni has not opened yet but its literally been in my tank for an hour lol.
