Betta fish enthusiasts all want to breed beautiful and strong betta fish with great fighting spirit. However, for beginners, breeding betta fish is not an easy task. In this article, we will guide you on how to breed betta fish from A to Z, as well as share some effective tips to help you succeed and achieve the highest number of betta fish.


Step 1: Preparation

Before breeding betta fish, you need to prepare a plastic tray or container with a water capacity of 15 to 20 liters. You can also add a betel leaf to create a place for the male fish to blow bubbles, and some small pebbles to provide hiding spots for the female fish after breeding.

Step 2: Introduce the male and female fish

Next, introduce the male fish first. Then, cut a plastic tray and place the female fish inside to let the male and female fish get acquainted with each other for about 5 to 7 days to reduce their aggressiveness.

Step 3: Release the female fish

When you see the male fish blowing a lot of bubbles, it’s time to release the female fish. The male fish will usually chase and nip the female fish, but eventually, when the female fish swims under the bubble nest, they will embrace each other, and you will notice the presence of eggs.

Step 4: Remove the female fish after laying eggs

After laying eggs, the female fish may become motionless, while the male fish quickly picks up the eggs and places them in the bubble nest. They will embrace each other a few more times until the female fish stops laying eggs. In some cases, the female fish may help the male fish pick up the eggs, while in others, she may eat the eggs. Therefore, it is best to gently separate the female fish and place her in a separate tank.

Step 5: Wait for the eggs to hatch

It takes about 2 to 3 days for the eggs to hatch. During this time, you can feed the male fish a small amount of food. If the male fish does not eat, you can use a dropper to remove any uneaten food. The male fish will also constantly change the broken bubbles as the baby fish cling to them. After a few days, the baby betta fish will start swimming horizontally and leave the nest.

Step 6: Remove the male fish

At this stage, you should separate the male fish from the fry and allow him to return to his normal living environment for feeding and rest.

Tips for breeding betta fish:

  • After breeding and separating the male and female fish, observe their health. If you notice any injuries on the female’s fins or the male fish appears exhausted, you can add a few drops of Maroxy solution to the tank to help them recover and heal.

  • When removing the male and female fish from the fry, do it gently and minimize strong water movement to reduce the impact on the baby fish and prevent any casualties.

  • During the first 3 days after hatching, baby betta fish are very small, around 1mm in size, and they rely on the yolk sac for nutrition, so there is no need to provide external food. When the yolk sac is absorbed, you can start feeding them with small live foods such as micro worms, brine shrimp larvae, or daphnia.
