I'm half-desperate to find a breeding pair of Betta brownorum. I absolutely adored that little guy. He was so shy, and spent most of his time sleeping inside his little tiny round pot, and he NEVER ate flakes, pellets, or anything but live and frozen food, but he was one of the cutest little fish I've ever had. I was always looking for a mate for him, and could never find one.
I want a pair of Betta imbellis, too. Been looking for them for ages, and been virtually begging the fish store on the other side of the valley (big valley, mind you, and I drive there every week) to order them in for me. So far...no luck. The owner THOUGHT she had some, and was so proud that she had gotten them for me, but they turned out to be Croaking Gouramis....
