Bettas can drop as many as 1000 eggs, but usually only about 100-200 make it to the nest. The largest spawn I've heard of contained about 800 fry.
Several hundreds
any where from 50-1000
a range to 50 to 1000
They can have 50 t0 1000. It really depends on how old the fish is, how big it is, and how well it was conditioned.
Male Betta's do not have babies. The female lays the eggs, the male fertilizes them and then takes care of them in a "bubble nest" that he builds until they hatch.
Yes
No. A male Betta is needed to spawn out the female and fertilise her eggs.
No, the male should be kept with the babies. Once the babies are adults, the mother can live with the females.
