Bought 10 female betta

Only 2 manage to survive ..

Question to ask ..

1 . How come my male betta nest breaks from day to day , and he has to rebuild it ?

2 . A female betta release its egg , even before spawning ? How come is this so .. *was separeted in a transparent container from the male as an introduction*

3 . What is the water PH level , temperature for breeding betta ? different source gave me different value , so I am confuse

My parents betta died after spawning =(

Another 9 female betta died .. no idea why
