Acquire the Fish
You will need to acquire a male and a female Chinese fighting fish. Make sure that you get ones that are healthy and it is best to get these from a reputable pet store. Keep them separately at the start. The ideal age for breeding is between three to eight months. Feed them well, mainly with food such as live brine shrimp to prepare them. The best time to breed will be when the female is fat as she is full of eggs at that time.
The Right Conditions
Make sure that the conditions are right for breeding. You will need the aquarium to have water with 7 PH and make sure that when spawning the temperature is 82 degrees Fahrenheit. Reduce it to 78 when the eggs are being incubated as a temperature of 82 degrees will kill the eggs. There should be some plants at the base of the aquarium though make sure that there is no sand on the bottom.
Add the female Betta to the tank and after a couple of days, put a glass chimney over her so that she can swim in it. Add the male to the tank afterwards. When the male is ready to spawn, he will blow bubblenest. Once the bubblenest has been made, remove the glass chimney and the fish will mate probably in two to three days.
Once the eggs have been released, remove the female from that particular tank. The male will fertilise the eggs at this point. The eggs will hatch in a day or so and will hang to the bubblenest for about 36 hours. Once the newborns start swimming horizontally, remove the male from the tank.
