Your female Betta can not be pregnant because bettas do not get pregnant. If she is plump and full of eggs(ova) don't worry. If she is not spawned out by a male, her body will naturally reabsorb the unreleased ova when it is good and ready.
She breeds with a male Betta Fish.
they are spawners. they dont get "pregnant"
It's impossible for a female to be pregnant. They are egg layers. Females can be eggy, though.
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
No.
Np, but they will bite. Yes, they will fight to the death.

No. Betta fish will attack each other no matter the sex.
Your betta fish is a female if she has smaller fins than an average male.
Yes they will.
