L46 - 28pics to sex 7pcs, thank you

[awth]

Recently, I have acquired 2 more wild caught zebra, in addition with my 5pcs, now I have total 7pcs of them. I strongly believe that I have read almost all the threads about how to sex them in this forum, however, I still don't have a clue on their gender. The more I look at them and the more I read about how to sex them, the more confuse I am!!!

Behaviour:
Ind #1-4 and 6, like to hide among the rock and I never seen them in the caves.

Ind#5, the Youngster, it would ocassionally go inside the cave, but not very often.

Ind#7, I just bought it recently, and when I released it to the tank, it went directly into a cave, and I feel that it spend more time inside a cave than any of the rest.

Please, could anyone kind enough to help me sex them and tell me why you think so. Thank you very much.

My guesses are as follows:
1 don´t know, but I lean towards female
2 don´t know
3 male based on the shape of the genital papilla
4 female based on the shape of the genital papilla and overall body shape.
5 male based on the shape of the genital papilla and head shape.
6 female based on the shape of the genital papilla. The shape of the body tells me little. Pectoral fin spine is thin.
7 male for sure. That kind of heavy odontal growth only occurs in males. Genital papilla is also definetely male like. He is way to thin, but you already know that.

Haavard Stoere: Thank you very much, I just bought #7 for couple of days, his is picking up his appetite, I hope he will gain some weight very soon.
