When to Breed Guppy?

Guppies are typically four months old before they can be bred, so to repeat the above for three generations would take about 12 months before your first cross.

How do you know when guppies are ready to mate?

Know when your fish is about to give birth.

When your female guppy is ready to give birth, her stomach will be very large and her gravid spot will be a deep black (or dark maroon if you are breeding albino or blond guppies.) Her stomach will also square off like a cardboard box rather than growing rounder.

How do I encourage my guppies to breed?

When you are ready to breed them, raise the temperature 2° to 3°F. Guppies like having a handy hiding place or two, so you can make them very happy by building small openings with rocks, and then add a few spots of dense foliage accompanied by natural-looking gravel.
