Before they paired there was a lot of chasing between my females and males - mostly the female going after the female.Back when i had more pairs i tried a male with two different females. I did see them dig pits but no actual breeding behavior, but i guess there could be many different reasons why they didn’t succed. Water values, food, etc.
I think the male chased the first female more than the second.
I believe all the females where the same age.
