Thanks for the info Robert. The Advanced Aquarist article points out that Black Pearls stopped producing flames, I guess if I had looked harder I wouldn't have had to email them.
My first fish were a pair of tank bred black and white clowns, and those guys were practically bulletproof. If anything showed me that tank raised was the way to go, that was it. The extra money spent on them was definitely worth it. Likewise, I would have paid the extra cash to get three flames, like I was planning to. It's just disappointing that this isn't even an option now.
