Cook, not all polythoa are from the Pacific, we have polythoa and zoanthis, right here in Florida waters. Very similar to yours in fact. If yours are purple(they look a little purple,) they will be worth more than brown or grey ones. The brighter ones always are the best sellers. Some people just have to have the newest things out, then in a year, everyone will have them. If you do trade or sell, ask for a reasonable amount, but dont sell your self short. They look good from here. Steve.
