Its all marketing: fancy names, descriptions and back stories. I sell a lot of frags locally of this colony (it grows like a bad weed) which I call "Doug's Zoa's" because I got them from a local guy named Doug. I ask between $5 and $10 for 10-30 polyps. Or you can buy something that looks exactally the same to me from one of the online dealers called Sunshine Zoas for $5 per polyp. I've got a lot more examples if anyone wants to hear them...
