Hi. I'm trying to breed with guppy's. i have bred some but my female guppies never have more than 2-15 babies at 1 birth. I want to know if a bigger guppy female have more babies than smaller females? I have bought 2 female guppies about 2 weeks ago. both of them are alreary pregnant they are about 7cm lang wiht there tails. And the guppy females i alreary have and that have bred are all 3cm with tails. That the one's that only have birth to about 2-15 babies at a time. So will the new guppy females i have now have more babies? Please help!!!!
