No, unless their lesbian.
No. Betta fish will attack each other no matter the sex.
Female beta fish are better in this way, they don't fight, allowing you to put them in a tank with each other as well other fish!
yes if they are too close
No, they can live alone or with other female bettas. They might bite each other but won't kill.
Np, but they will bite. Yes, they will fight to the death.
The simple answer is no.
yes betta fish have to live alone or one will kill the other.
no because the male and femalebetas are the type of fish that live alone. therefor since their opposite sex then there is a chance of them being OK with each other, so if there is another fish with them then they will attack it and eventually killing each other.
Betta's are pretty good with other fish, it's rare that they will fight, maybe with other betta's
No. You need one of each.
Well, betta arn't the smartest fish. It probably spreds its fins out because it "thknks" there is another male fish in their so it wants the female to pick him... Also I advise you don't put 2 male betta fish together because they will REALLY TEAR EACH OTHER APART!
no because male betta's are really aggressive to other betta's which plakats are male's. but female betta's can stay with other females. don't try to, one of your betta's are going to end up dead.
