Sexing... thats a tough one. The facial banding is very thick and dark which points to male. The vertical lines appear to be fading which also indicates male, but the lateral line remains dark which females tend to have. The head is also slender which makes me think female...
If I had to make a wild guess in the dark right now I would say female, but I am not sure about that.
Edit: Ok, I just compared pics of my old male and I do think female more convincingly now. Here's a pic for comparison.
I can't help you with the sexing but I wanted to say that both of you are very, very mean people. Posting pics of amazing jags like that. You should be ashamed of yourselves. Beautiful big barbs too. Tsk, tsk...... :wink:
