Male or female (A.norberti+A.bitaeniata)

[aquaeric13]

Hello,

a few weeks ago I bought A.norberti and A.bitaeniata.
Now of course I want to know which is male and which is female.
I hope you can help me,especially the A.bitaeniata are still very small.

Photos 1 - 3: probably female, but might also be a juvenile male.
Photos 4 - 6: male
Photo 7: male (right); probably a male (left)
Photos 8 - 11 males

FYI, female A. norberti rarely show markings in the caudal, definitely nothing prominent.
