Breeding Guppies
Hello D...
A few ideas for the future. You don't need to buy male Guppies. Just buy the females. Males and females are raised together, so the females are already pregnant.
Since you already have a male, you need to get a couple of more females, so the male can take turns chasing one female at a time. This gives the other females a lot of rest.
Float some plants in the tank. Water sprite is the best. It provides nourishment for the fish and cover for the females and eventual fry.
You really need a larger tank. The smallest I'd recommend is 20 gallons. A 30 G is better. I keep Fancy Guppies, but in much larger tanks. Guppies need a lot of room to swim.
One other thing. If conditions aren't right, the females can put a hold on giving birth. Just something to keep in mind if you want to consider giving your Guppies a larger home.
