the dominant male with the female.
I do not know if you noticed, I have a white females and two females of a pale yellow color.
It is very curious that difference.
the other male dominated, unfortunately he died after a fight with the dominant male, yet the aquarium was 200 liters.
For me it goby must have several females for one male.
White female and female pale yellow.
Although the lighting is different, you can see the difference in color.
