Sometimes they will but not offen very few times will the male betta not bother the female to sickness or death but if you provied a place for her to run away to like a plant.
Male bettas should be kept alone. Female bettas can sometimes be kept with other fish, but in a large community tank. Bettas need their space!
yes, if you put another male in the tank they will kill each other, if you put a female in the tank and they are not ready to breed the male may attack the female and kill her.
Only male Bettas fight and they will only fight with other male Bettas. A male Betta will kill the female if she will not spawn with him. He will also kill her after she has spawned if she is not removed.
His gills will flare up.

The male will puff up his gills to scare the female by looking bigger. If the male betta looks straight at you when he is flaring, it makes him look bigger. He follows the female to scare it away.
Generally they will not get along.
the males have longer fins
Like almost all animals, bettas can be male or female. Adult female bettas typically have shorter fins than adult male bettas, and are often less "showy" or brightly colored than the males (though colorful females definitely exist). Female bettas have a white bump on their stomachs, called the ovipositor-- this is where the eggs are stored, and where they are released from when mating occurs.
They will both eat about the same.
No they cant. Female bettas carry eggs that the males squeeze out of them during mating, then the males fertillise them.
You can NOT keep female and male bettas together! Male bettas can get very aggressive and will fight to the death. Make sure to separate your bettas.
