Thai betta can reproduce 4-6 times a year, each time can lay 10-100 eggs. Their growth and development speed is relatively fast compared with other fish, and it usually takes only 4-8 months from birth to maturity. If properly raised, it may be possible to breed in 3-4 months. Their reproduction is not restricted by seasons and time, and they will reproduce as long as the breeding environment is proper.

1. Pairing: When Thai betta breeds, breeders need to prepare a separate fish tank for them, and then put mature male and female fish into it. At this time, the male fish will dance a courtship dance until the female fish accepts their pursuit. This completes the pairing.

2. Reproduction: After successful pairing, males spit out bubbles and build nests one by one. Then dance with the female fish. When dancing, the male fish will wrap the female fish tightly with its tail, and the female fish will produce eggs under the wrap of the male fish. After the female fish lays eggs, the male fish will immediately go to the front row of sperm, and the reproduction is completed at this time.

3. Hatching: After the male fish is spermatized, the fertilized eggs will be put into the built fish nest one by one. And they will always be there to guard. If the nest breaks, they will come forward to repair it, and they will fan the water with their fins to provide oxygen to the eggs. The small fish will not leave until they hatch successfully.
