Q: Can my female bettas live in a species tank?
A: Yes, but you need at least 10 gallon. And no more than 6 girls, no less than 4 will usually get along. Make sure you watch close to make sure no one gets ganged up on. You can keep a ton of girls together, it is really unlimited. but I wouldn't ever keep more than 6 in something as small as a 10 gallon.
