Identifiyind Male Or Female Guppy Fry

[alexbinge]

hi guys i have had another batch or fry and i was wondering what the esetest whay off telling if they are male or female. I have tryed looking at there fins but it is still a struggle.

They will all look female for a good few weeks, or couple of months. You'll just have to keep inspecting them until the males start to form their gonopodia

impossible to sex until the male's fin develops from 5-6 week's on.

I can sometimes sex then from 3 weeks but it's difficult.
