Yes, but fry rearing is time consuming, and, IMO, breeding them isn't worth it all except the experience. If it's for money, you'll be lucky if you make the money back you spent on the parents with all the fry combined.
You'll need 50+ mason jar sized jars to seperate males into once they start maturing. You'll need to keep those in a warm place wear the ambient temperature is around 75F-80F and you'll need to change water out of the jars on a daily to twice daily basis. You'll be raising fry for at least 3-4 months.
You should condition the male in female at least 2 weeks prior to breeding, and it should be done in seperate tanks. Feed them good foods, live/frozen foods as the main part of the diet will provide the best condition. The tank level should be no more than 6'' high and there should be plenty of floating plants. The male should be in the tank meant for breeding before the female. Use a vase or floating guppy breeder (the plastic ones that float in the tank, but allow water to pass through them). I prefered the guppy breeder to the vase when I bred them. You'll put the female in the breeder so the male can see her but not get to her. He should start building a bubble nest. When it's finished, he will try to draw her to it, when he starts doing this, release her. If the male betta starts attacking her heavily, place her back in the breeder. If no, let them be. If he does though, wait for him to start enticing her, then try again.
When they start spawning, you should be there, because when their done, he will start attacking her. She will need to be removed with care so as not to disturbe the nest with eggs in it.
The fry hatch in 2-3 days, dad should be left with them until they are free swimming; then he should be removed. Feed them a very finely powdered fry food. I haven't tried liquid fry food, but it may work also.
It may take the male a few tries at spawning to get the hang of things, so if he eats the eggs or ignores them, whatever, don't worry about it.
The female and male should get a 2 week break in between breedings if there is no fry/eggs.
If you have anymore questions please ask.
