Those are popular at my club auctions. I love them- 3 pair that are about 2 years old. The colors get better over time- they're really active and fun. Buddy at the club said they're easy to breed if you pull the female when she's showing (which is pretty much always), but I haven't bothered to try. I got 6 butterfly goodeids from the same guy and ended up with 80 of them in a 29 gallon tank- they just went crazy. I have 6 in there now LOL.
