Sexing Platy Fry

[zig]

Hi all

I have platy fry that i inherited, well when i say inherited i bought 1 female platy at my lfs and she was obviously pregnant when i got her and now i have quite a few fry, i have no problem keeping them as i have enough room with a couple of tanks and another large tank on the way, so plenty of spare capicity.

But i really want to seperate the males from the females as soon as possible to stop having a potiential population explosion on my hands.

So my question is how soon should i be able to tell the male from the female fry (these fry are probably 5 weeks old at this stage) and how soon would platys start breeding normally.

Thanks alot.

i'd say after three months.

In my experience, platties take a little longer to develop... I would also say around 3-4 months.

Thanks for the replys guys, but do you mean to start breeding or to be able to sex.

My platies are about 3-4 months old now and you can clearly tell the males from females I never seperated males from females while raising them and now I've got them in my 55 gallon.

Whatever fry are born in the 55 gallon will most definitely get eaten so I'm not worried about keeping the males and females together.

Hi, I have found, in my experience, that the first sign is that the anal fin is larger on the female fry, and as for the males, once the anal fin starts to develop into a point you should then separate them, (before the gonopodium develops). Also remember that if you are not sure about any of the fry always keep them with the males.
