Guppy Sex

[LilyRose Tank]

Hello there. I have a single guppy fry born 4/5 April 2010, so is a month old now. I realise that all fry look female but at what age do the males develop their gonadopodium? He/she has "female" anal fins at present

My 2/3 month old fry is just developing his gonopodium.
