My guppy fry are 10 days old now and i was wondering how long it will be before i can tell the sex of them. What sort of things do i look for when trying to tell them apart?
thanx

At 10 days old you're not gonna see alot of changes. At 3 months they will have gained alot more colour and they'll be sexually mature. At this time you can differ them by their colouring(females have little to no colour on their robust body, males bodies will be covered in colouring wiht longer fins ), they're body shape and fins(males have a gonopodium, a rod shaped belly fin and just guess whats it's used for ). Here's a link showing the different fins on the males from the female: http/www.showguppies.com/helpline.htm
