I couldn't find them in a town of 150,000! I accidentally found a woman an hour away who had started breeding hers and would sell me some. Breeders and Fish Swaps would be the way to go. AquaBid.com often has them up for bid. A guy named ApistoDave (David Soares)
My Webpage often has them listed at less than he sells them on his website (that has a min. purchase amount); and man, are they beautiful! Do some hunting online and you might find some breeders. I have other links if you'd like them.
Edit: I'm not sure why they aren't found too much around here, but I really don't think they are considered "rare". I am, however, planning on introducing them to my community.
