How to Breed Betta Fish

Betta fish, also known as Siamese fighting fish, are popular freshwater aquarium fish. They are native to Southeast Asia and are known for their bright colors and long, flowing fins. Betta fish are popular pets because they are relatively easy to care for and can thrive in a small tank. Their beautiful features and appearance is what makes it so appealing to watch and has gained enough attention among the fish keeping community.

About Betta Fish

Betta fish are territorial and can become aggressive towards other males, which is why it is generally recommended to keep only one male betta per tank. Female bettas can also be territorial, but they are generally more peaceful than males and can be kept in a community tank with other non-aggressive fish.

Betta fish have a lifespan of 3-5 years, although some individuals have been known to live longer with proper care. They are sensitive to changes in water quality and temperature, so it is important to maintain a consistent environment and to perform regular water changes.

Betta fish are omnivorous and should be fed a varied diet of both plant-based and protein-based foods. They can be fed a combination of pellets, flakes, and live or frozen foods such as brine shrimp, daphnia, and bloodworms.

How to breed Betta Fish

Betta fish are one of the easiest fish to breed for hobby and profit. You can breed them from the comfort of your homes and still manage to create a small passive income by selling them at your nearest pet store or any online platform.

Tools needed

  • Thermometer
  • Heater
  • Breeding tank
  • Divider
  • Air pump


  • Breeding pair of Betta fish
  • Brine shrimp
  • Fresh water

Setting up separate breeding tank

Start by setting up a separate breeding tank. This should be at least 10 gallons and should have a heater to maintain a temperature of 78-82 degrees Fahrenheit. It should also have a sponge filter and a removable divider to separate the male and female.

Choose a Breeding Pair

Choose a healthy male and female betta. Look for fish that are colorful, have long fins, and are active. It is best to choose fish that are at least 6 months old, as younger fish may not be fully mature and may not breed successfully.

Separate the Bettas with divider

Place the male on one side of the tank and the female on the other side, separated by the divider. This will allow the fish to get used to each other’s presence before breeding. you can use any thin cardboard piece as a divider.

Bubble Nest

After a few days, the male will start to build a bubble nest. This is a good sign that he is ready to breed. The bubble nest is made up of small bubbles that the male blows and sticks together with saliva. It serves as a place for the female to lay her eggs, and the male will later use it to transport the eggs to a safer location.


When the female is ready to lay eggs, she will appear swollen and have vertical stripes on her body. This is known as “barring” and is a sign that the female is ready to breed.

Remove the Divider

Remove the divider and allow the male and female to breed. The male will wrap his body around the female and fertilise the eggs as she lays them. This process is called the “spawning embrace.”

Eggs are placed in bubble Nest

As soon as the eggs are laid, the male will pick them up in his mouth and place them in the bubble nest. He will continue to do this until all the eggs have been collected.

After breeding, remove the female from the tank and leave the male to care for the eggs. The male will fan the eggs with his fins to keep them oxygenated and will also guard the nest from predators.

Hatching of the eggs

The eggs will hatch in about 48-72 hours. 

Care for the Fry

When the fry are free swimming, you can start feeding them small amounts of betta fry food or newly hatched brine shrimp. I would suggest brine shrimps as the best source of food to feed your betta fish fry because they are easy to hatch, feed and high in nutrients. The process of hatching brine shrimps is easy and has no mess involved.

As the fry grow, you will need to gradually increase the size of their tank and provide them with proper care and nutrition. It is important to maintain proper water quality and to keep the tank clean to prevent the spread of diseases.
