Males are usually bigger and more colorful than females.
you can tell if its a boy or girl by the fins the male Betta has long fins and the female Betta has small fins
A girl Betta is dull and not as pretty as the male. But, a boy Betta is colorful and pretty to attract the female mate.
Yes.
Boys have more colors than girls....THE PRETTIER ONE
A female betta has very small fins with a long body while the male betta have lots of nice flowing fins.
No, they are fighting fish. They will kill each other no matter what sex they are.
If it is a fantail betta, the boy will have very large, flowing fins. If it is a girl, the fins will be short and not very fancy.
It's all in the tail. the males is larger and longer and the females is shorter.
yes
No, they can live alone or with other female bettas. They might bite each other but won't kill.
it depends the species but most of the time...no. males are way aggressive. unless you are an expert aquarist i wouldn't
Maybe your female betta is a lesbian lol
