Separate them in the tank by placing a glass partition between them. It is the males that fight.
No. Betta fish will attack each other no matter the sex.
Betta fish of the opposite sex will not always kill each other. It is actually an uncommon occurrence.
I have never seen any Betta fish's go crazy, but, it is possible.
yes
The Betta fish runs away when facing another Betta because its the first time facing another one. Or its just scared of it and doesn't want to fight since its not use to it and its a FIGHTING fish. But once its use to it the other Betta they well start getting up close to each other face to face and start ripping out each others fins out and basically trying to kill each other chasing each other around.
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.
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!
other Betta fish and the bigger fish.
No, they can live alone or with other female bettas. They might bite each other but won't kill.
No, unless their lesbian.
NO they will attack each other
No, they are fighting fish. They will kill each other no matter what sex they are.
