We all know how difficult it is to identify the sex of these fish, so please post a picture in here and we'll try to help you (or at least give an educated guess!).
Well I finally managed to get four more Zebras (to add to my lowly two) from a friend of mine and I would like to know people's opinions on their sex.
My Opinion (L to R)
1. Male
2. Male
3. Female
4. Female
I have no other pictures of them as I still do not have them yet. But the original picture is much bigger (2022 x 1288) and actually shows details such as the facial region, maybe you can zoom in and it won't distort or resize it in photoshop.
