The time for Thai betta to pair fish cannot be determined. How long it takes depends on their pairing. If it goes well with fish, they can succeed in a few hours or a night. If it doesn't go well with the fish, it may take 1 day or several days.

When Thai fighting fish are confronted, the male fish will keep dancing to attract the attention of the female fish. If the female fish accepts it, it means that the pairing is successful, and the male fish will spit out follicles. If the female fish doesn't accept it, the male fish will keep dancing. Some male fish may also take a tough approach to pairing. Breeders should pay attention to observation when they are paired. If male fish attacks female fish or female fish is injured, they need to fish out the female fish as soon as possible to avoid more serious injuries.

Thai betta begins to breed after successful pairing. When female fish produce eggs, it is best for breeders to fish them out and raise them in other containers. Because they may get hurt when they breed and pair.

Be careful not to fish out the males together, because they have the habit of protecting eggs. When the fish nest breaks, they will come forward to repair it. But also fanning the water with double fins to provide oxygen for fish eggs. At this time, be careful not to make too much noise to avoid scaring the male fish.
