No, you should never keep a male and female betta fish together for long time periods. They should only be put in the same tank for breeding purposes and then separated after.
Np, but they will bite. Yes, they will fight to the death.
No. Betta fish will attack each other no matter the sex.
Only female Bettas can be kept together. That too will only work if they are given reasonably roomy conditions and plenty of cover (plants) and hidey holes. Male betta fish can/ will fight to death if there is another male fish in the tank, a male will sometimes eat a female so your best bet is to have a single betta or a female and a female.
The simple answer is no.
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 betta fish have to live alone or one will kill the other.
Betta's are pretty good with other fish, it's rare that they will fight, maybe with other betta's
No, unless their lesbian.
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.
No, they can live alone or with other female bettas. They might bite each other but won't kill.
Yes all bettas can mate with other bettas. " regular betta fish" there are different types and they can all breed together.
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.
