How do betta fish have a baby without?

Betta fish reproduce through a process known as spawning, where the male builds a bubble nest and entices the female to lay eggs. The female releases eggs, which the male fertilizes and then collects in the nest. After fertilization, the male cares for the eggs until they hatch, providing protection and maintaining the nest. This reproductive strategy allows bettas to successfully raise their young without extensive parental involvement from the female after spawning.
