I have two ( originally three but haven't seen a third in quite a while now ) guppy fry that came from one or more of 5 females in my 10 gallon. They are about two months old now and I am thinking that I should sex them before I have a fry boom. Or is it too late now?

Anyways, I tried to get pictures of the fry but they are both very agile and quick so bear with me on the poor quality. What are they?

They are still too young...

Okay. At which age can I sex them then?

Is the gravid spot visible? Usually it is the first sign that you have a female and can be visible pretty early. I can sex mine in as little as 3-4wks sometimes. The method however, is not perfect. The gravid spot just could take a little longer to show in some cases.

In 4 months even the males will have near full colors and may have a gonopodium visible. It can be done much earlier.

Aren't gonopodiums distinguishable before 4 months? I'd go by gonopodiums to confirm males- at the point where you can see gravid spots, chances are excellent that female is already gravid LOL
