Any other Betta can kill a female. Bettas are so agressive that they will even kill their babies if they wanter to. Also, larger predators can kill.
A small filet knife!
Np, but they will bite. Yes, they will fight to the death.
yes betta fish have to live alone or one will kill the other.
The Betta fish want to kill eachother. That's what all Betta fish want to do, that's a natural thing.
it could be for territorial reasons.
My sugestion is that you sell them because the female wil try to eat them and the male will kill the female and you will loose you female betta fish so give them to a pet store or sell em
No, they can live alone or with other female bettas. They might bite each other but won't kill.
Probably not. The female is more streamlined and designed for a fast get away. She usually has to flee from any marauding male who may decide to 'have' her and/or kill her.
why would you want to kill a betta D:
a male Betta will usually like the company of other fish but will fight or kill others of their kind also they might fight guppies cause they look similar to a female Betta.
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.
yes
She breeds with a male Betta Fish.
