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.
Q: can my females live in my community tank?
A: I have found that females can live with exactly what males can. They are aggressive too. They might not fight other girl bettas, but they are fiesty little buggers. Once again, some people have kept them no problem with other things, but it isn't always a good idea, nor is it usually safe.
