No all male bettas should be seperate! If you have 4 or more girls you can start a sorority, which is just a tankful of females coexisting. But if you don't have at least 4 girls you should just give each female a seperate tank, and not start a sorority as you would need at least 4 girls. A 4 girl sorority would need an 8-10 gallon tank, and each seperate betta needs at least a 2 gallon tank. Find out more about sororities by looking around on this website, people talk about them all the time. Hope this helps.
I like bettas. Why would I be here if I didn't?
