Ken f1s will have a big variation in charecteristics. Just like plants. When you start breeding the traits you want and start gettn into f2, f3, f4+ you can start to keep the traits you want. You gotta figure there were more than 1 pair of bahias around as well. THose are just the originals. So there will be differences in everyones bahias...just depends who bred them. Remember when your's were first imported @200ea. Now your seeing f2s in the US go as low as $40ea.....sometimes cheaper. In sg the prices are even lower....even on the azuls and other kelberi variants. ITs their ability to keep tropical fish outside in ponds. They are able to breed them much easier thus making the number of bass much more available. I wish we could do this on the mainland.
