Thai betta fish can reach adulthood in 4-5 months in general, and their growth and development speed is relatively short compared with other fish. But when you become an adult depends on the way you raise it. If the breeding environment is comfortable and the food is abundant, they can mature in 3-4 months. If they are raised in a harsh environment and lack food, it will take five months for them to mature.

In addition to the time of birth, breeders can also judge whether they are adults by their body length. Under normal breeding conditions, Thai betta can breed when its body length reaches 4 cm. Although they can reproduce when they are mature, breeders are not advised to let them reproduce immediately. Because they are just mature at this time, and their functions are unstable, immediate reproduction may affect the quality of reproduction. Therefore, it is suggested that Thai betta fish should be 5 cm long before breeding.

Thai betta reproduce about 7-10 days after the first production. Although their reproduction frequency is relatively high, it is not recommended to let them reproduce frequently. Because this will not only harm their bodies, but also affect their life span.

The captive Thai betta fish can be bred once every 1-2 months, and the number of breeding should not exceed 4 times a year. In this way, they will have enough time to recover, and their offspring will be healthier.
