Female bettas are usually less colorful and have short fins.
Your betta fish is a female if she has smaller fins than an average male.
If you would like to know what gender your betta is, look for the egg spot. (for females) It should be a small white cloud between the head and body. If your betta has one, it's a female. If your betta doesn't have one, it's a male.
Maybe your female betta is a lesbian lol
Female beta is a murderer.
A female Betta in breeding condition will look plump and have a rounded tummy area.
Male betta's are more colorful then female's
From a female Betta. Then the male Betta fertilizes them when they breed together.
When a female beta is ready to breed she develops a horizontal line the length of her body.
If they are not too old and the female is ready, then they will mate.
If the female is chubby around the tummy area you could add her but be prepared to remove her if the male gets too boisterous. If he starts building a nest then you know you are in with a chance.
She breeds with a male Betta Fish.
