Swordtail Fry Grown Up?

[Keva]

I've got swordtail fry over 3 month old now and im just wondering when they start to show what sex they are?

Some take up to 8 months but you should be able to tell around about now by looking at the gonopodium.

thanks when do the males swordtails grow?

 

[Joshwainwright]

I think they should be visible around 5-6 months however that may vary if you have older males with tails in the tank with them. When it does happen, you could see them get slightly aggressive.
 
It's just a case of being patient
