As many have said, red is common because of how dominant it is. It's why I'm trying to keep red out of my lines.
If you want purple, I suggest going to Chard and asking if they have any purples left. They have some very nice fish. This is their AquaBid link: http://www.aquabid.com/cgi-bin/aucti...seller&Chard56
At the moment, I see them with black orchids, a marble, various reds, and 2 purples.
Wow she's done some work with those purples! I'm excited to start to see these more. They got to be a bear to try to breed though...
Feel free to message me any questions, I'll try to help the best I can!
