Breeding Basics
Adding guppies to your aquarium opens up exciting possibilities for breeding these colorful fish. Guppies are livebearers, which means they give birth to lively fry instead of laying eggs. Under the right conditions, you could see 20 to 100 new guppies every 4 to 6 weeks—now that's a lot of little swimmers!
To keep things smooth during breeding, aim for a ratio of one male to two or three females. This helps reduce stress and aggression from the males, keeping your tank a peaceful place.

Maintaining stable water conditions is key! A pH of 6.8 to 7.8 and a temperature around 75 to 82°F will help ensure your guppies thrive and your fry survive.
Once the fry are born, feed them fine crushed flakes or specialized fry food to support their growth.

In a community tank, rasboras are the friendly neighbors you want. Generally peaceful, they get along well with various community fish, adding harmony to your underwater world.
