Thai betta can reproduce.

Put the male fish into the breeding tank first, and after 3 hours, the female fish (take a transparent box, put the female fish in the box and put it in the breeding tank) must be adult and bring egg. If the female fish has a marriage color, and the male fish is spitting bubbles, it means that the husband is in love with a concubine. When the male fish spit bubbles to a range of about 5*5, you can put the female fish in.

Usually they will mate the next day, so don't visit Thailand often after the tank is combined Betta, it is recommended to put Thai Betta in a quiet place.
