First, Select Some Quality Brooders

To have a successful breeding of any fish, you need to select the best brooders from the bunch. This will ensure that you pass down strong genes and traits to the next generation of fish.

Here are some ways that you can select the best brooders from a group of Guppy fish.

Observe The Physical Health Of Fish

When selecting brooders, we must always look for the best and the fittest of the group of fish. By choosing these strong individuals, we could know how the next generation will be.

Check For Bright Colour Patterns

When choosing brooders, we must look for the best color patterns or the most attractive color patterns of a fish.

Consider The Size And Age

As Guppy fish reach sexual maturity at about 3-4 months, isolating fish about that particular age will give you the best crop of the available bunch. Because if you choose a younger or older gish, the success of the fish breeding will be lowered.

How to Separate Males and Females in Guppy Fish?

After selecting the best brooders from your fish group, let’s see how to separate the males from females in Guppy fish.

Males are usually more colorful and smaller than females. Female fish tend to have more dulled coloring compared to the male. Males also will have long-flowing fins, and the caudal fins of males are ornately shaped.

Females have shorter fins, and their anal fin is fan-shaped. Anal fin males are modified into a thin rod-like structure.

One of the most successful ways to identify a female fish when close to the breeding season is by the gravid spot. A gravid spot is a dark spot near the anal fin. This will be darker when they are ready to mate and much darker when they are pregnant.

Tanks Setup for Guppy Fish Breeding

When setting up the tanks for Guppy fish, ensure enough room for them to breed. At least a tank with a capacity of 20 gallons or 76 liters is needed for optimum reproduction. Then, it would be best to focus on maintaining a cleaner tank by adding a filter.

When choosing a filter, use a filter that is not too powerful, like a sponge filter. Then, the water temperature of the tank should be maintained at 24-28 ℃ for optimum breeding conditions. Make sure to keep the pH level of water at 7-8 and water hardness between 10-20 dGH.

The tank should look and feel like the natural environment. You can lay some fine-grained substrate, like sand or small gravel. And complete the setup by adding some live plants to make the background look more natural.

Plants like java moss and floating plants work well with Guppy. You can also add a light to stimulate the day-night cycle, which will help speed up the breeding cycle.

Breeding Process of Guppy Fish

Guppy Fish are livebearers. That means they give birth to live and free-swimming fry rather than eggs.

  • After setting up the tank, then place the selected male and female brooders into the tank.
  • After acclimating to the new environment, the male fish will start chasing the female in courtship behavior.
  • If the breeding is successful, the female fish’s gravid spot will become even darker, and her belly will swell.
  • After mating, you can remove the female fish into a separate tank, reducing stress on the female fish. If the mating was successful, you will be able to see guppy babies after 4-6 weeks. 
  • During this time, it is essential to feed the female with high-quality feed because it will determine how healthy the baby will become. Make sure to constantly check on the conditions of the female and maintain the water quality parameters like temperature, pH, and dissolved solid levels at optimum levels.

How good is Guppy Fish in Baby Care?

Guppy fish take good care of their young ones compared to most other species. As these give birth to free swimming fry rather than eggs, the tendency of the female to eat their own eggs is reduced.

While giving birth, the female will choose a hiding spot covered from the outer world. Once fries are released, they will have natural camouflage to protect them from predators.

Guppy females will sometimes eat the weaker offspring, which will lead to having a generation of good fish with natural selection.

Final Thoughts

So, this is the end of today’s article. We have talked about everything you need to know about guppy fish breeding. As these fish are easy to care for and even the breeding process is much easier, breeding guppy fish can be done by a beginner as well.

I hope I covered all you wanted to know about guppy fish breeding. I invite you to get some guppy fish and try out the breeding process, and it will be so fun.
