Female beta is a murderer.
Ur betta is ready to breed
The male will try to spawn with her. If she is not in breeding condition she needs to hide to stay alive.
It means they are getting ready to MATE
It probably means that your female (girl) Betta is a male that has not yet fully matured.
It means he hates you. Bettas flare their gills out when they're trying to scare another betta away, or to impress a female with how large he is.
Do you mean female and male? If so, then the female betta fish is smaller and less elaborate than the male.
It is courtship but be careful during the mating the male will kill the female then the male will make a bubble nest. When the babies hatch be shure to separate the babies or they will eat each other hope this helps
If you mean 2 other female bettas, probably not. Females generally are non aggressive and do fine with other females.
No they cannot. But if you're planning on breeding your betta fish I suggest you don't let the male and female share a bowl all the time. Because the female may not be particularly nice to the male. By that I mean she'll probably bite at him and other things so just be aware of that. Hope this helps :)
Betta's are super Territorial once they see another one they go for the kill and one they do their is no stopping it they stop until one is dead even with cory catfish's the will kill anything ( fish) in my book their the king of the world ( and by world i mean tank) so i wouldn't even risk it weather male or female a betta is a betta
I guess your Betta has a roundish tummy. That is its normal body shape. Bettas certainly can not be pregnant because they are egg layers and don't get pregnant.
