I haven't been really able to tell. Is there a picture that has the difference between a male and female platy? I think they're both the same gender, but one is smaller and darker so I always thought that was the female and they both have white poop.
Using this picture:
I think they're both females. But they've pooped 3 or 4 times and each time it looks white or clear and it's long and sometimes it has some specks of color in it which I'm hoping is the food.
You can sort of see one of the back tails in this picture
And in this one
Do they look like females to you? Do they red absorb babies that many times?
