Just thought I'd post something a little weird that I have been seeing with my spider lately.
To start off I was recently trying to breed him with my pastel female. I paired them for about a month and a half to see if she would accept him at all, but I knew she was a little young and I wasn't sure she was up to it yet. (She is 1400 grams otherwise) Turns out I never saw a single lock despite him laying with her constantly and coiling with her at times.
I decided to give it up and moved my spider back to his own cage for the last whole week and a half. During his longer time by himself I noticed that he seemed to be getting VERY stressed even thought it's his previous enclosure.
At least I -think- he is stressed because he was constantly wobbling and spinning in mid air as he tried to get out of the bin. He's never been this bad or wound up before IMO. He has also been very aggressive as of late and I figured it was to protect his woman!
Well, I didn't like the look of his crazy spinning so I tested it out and moved him back with my female pastel. Now he seems fine again. Still a bit aggressive and protective, but I think he was looking for his female in the other cage. He's always laying with her ect, but still I haven't seen a single lock. It's possible I might have missed one, but I don't think she is gravid nor ovulating. *shrug*
These are my observations. I'll probably let them go for a while longer to calm him down, but then move him back permanently to his own cage after that.
