Nope. Just stick with the female sorority. Based on my research, I wouldn't mix guppies and bettas whether they're male or female or whatnot. I just don't like the mix, for behavioral, environmental, and aesthetic reasons. 10g is just too small a tank to play with that kind of community. If you get male guppies, the female bettas will nip, at least that is my impression. If you get female guppies, you have babies for 3 months or longer and then your tank will become overstocked. Keep it to six ladies as the other members have suggested and you'll have a nice, active, and fun tank to watch. Put hiding places and plants and it will be a pretty tank and your fish will love you.
