I know Frank the owner of VIP Reefs. I worked (now retired) for one of his vendors and he is a good guy. He collects his own RFA's along with a staff member at the store. I bought about 12 from him way back when these really colorful RFA's were still pretty new and he was getting $80 to $100 each for the really colorful ones.
That was a few years ago and I sold many of them to friends (not what I intended, but I have persistent friends!). In the last year mine have spawned twice and I now have 5 full size adults, a dozen that are a year old and the size of a quarter and another dozen or more (they are very hard too find) that are babies from a new spawn. They are smaller than this (o) when they are released from the mother. And in a tank full of colorful zoas that makes them hard to find! There is more info here:
