I dunno how he got it. I used to work for a live rock company out of Tarpon Springs, and there were some similar corals on the rock we cultued both in the gulf and in the keys, but yeah, never that large. I paid $75 for it.
He says he has more. Is anyone interested? If you want I can go check them out and post pics if you are. I calle my old boss from the LR company, he said they are the toughest corals available, and able to handle a almost any enviroment, and normal reef tank feedings will sustain it.
