a female Betta is always pregnant!! But u will start to notice vertical lines on its body like this!!!!!!!!!! not like this ---------. if they are horizontal then your fish is stressed out
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.
It's impossible for a female to be pregnant. They are egg layers. Females can be eggy, though.
No, they can live alone or with other female bettas. They might bite each other but won't kill.
No they don't get pregnant. A female produces eggs, then during mating a male will squeeze those eggs out of the female and fertilise them. The eggs are then put in a bubble nest by the male who cares for them until they hatch.
