Guppy question

[GuppyLover]

I was wondering when guppy fry become sexually mature. I lost all my males and am left with 6 females and I want to breed them to a lyretail as soon as I can. I am hoping to get atleast some lyretail fry, but if I dont I was wondering if I could breed then back to the lyretail.

Usually male guppies reach sexual maturity around three months, you'll start to see the gonopodium develop.
