    I was wondering at what age can I start tell which sex my fry are? They are 2 weeks old today and I really do not want more than the mom is gonna have(I know she will drop for awhile and I plan on only keeping a few of the female fry and selling the rest my LFS will pay me 20 cents for female and 80 cents for males).

    If you have a lot of practice sexing guppy fry you can usually sex them at around 10-15 days old. Just take a clear glass with a little bit of water in it, put the fry in there, and use a magnifying glass to find the gonopodium or gravid spot to distinguish between males and females. If your not so good at sexing you can pretty easily tell the difference between the fish at around 21-35 days old.

    Mine are just over 2 weeks and I am starting to suspect gravid spots on some of my larger ones but I am not 100% sure (with the naked eye... really need a magnifying glass...)
