bettas are usually 2-2.5 gals each. You want to do the full size that the fish can get per gal. So guppies would be 1-2 inch so 1-2 gal per fish.
You could have max of 7 or so guppies with 6 female bettas. If you don't want to have any guppy fry, you could always just get female guppies as well. :)
Just because I don't type with candy and rainbows doesn't mean I'm being mean.
My opinions are based on research and experience. Ask for help!
