How could you tell if your white female crowntail betta is ready for spawning?

Question

I know that female betta especially dark color are easy to identify when they are ready to breed. Because they have stripes on them. But the white ones are hard to identify. Are there any way where you could identify it?

The female will show her genital papilla, which will be a small, white tube protruding near her a**s.

Answer 2
