Oh, we are MOST DEFINITELY still in breeding season! Naida BFA is sitting on her second clutch as I type (she didn't sit on her first, she ignored the eggs completely).
It seems to me that he chose you as his human and is making sure your husband understand that you no longer belong to him
I had to laugh reading about his 'game' when he sneaks behind people's feet, bite them and then rans away calling for Mama

(smart cookies, aren't they? - they do something wrong but they are so cute about it that you can't help but not be mad at them).
And I had a very strong feeling that the enclosure was not going to work so I am not surprised at all. They like to be in the middle of things and isolating them, even if they can still see us, is never regarded as a good thing by them.
