I got mine from VIP Reefs in Miami and they are online as well. He doesn't buy them from a wholesaler, he collects them himself (I believe he sells to other online and LFS). I also got a couple nice ones from Cultivated Reef in Maine at their online site.
BTW, I went to Kush Corals and they don't even have any anemones in stock, RFA, RBTA or any others!
I’ve never bought from these folks before but they have some nice (not uncommon though) RFAs for real cheap. Most expensive I saw on the site was only $30 with some only listed for $15.
I have puchased rfas from gotcorals.com and reeftopia.com. I highly recommend both. Gotcorals is more expensive but you get nicer looking ones. If u just want ultra rock flowers, go for reeftopia, i got them for about 18 bucks a piece AFTER shipping but I had a large order (the bigger the order the cheaper the price, my order was over 200, they are well known for selling good cuc so I got some cuc as well).
