Hi All,

Both my new collared lizards are head bobbing, it seems to be the little one that starts it, then the bigger one follows, and they lick each other a few times before going back to whatever they were doing. No push ups or aggression, neither one backs away when they do it, they are always climbing all over each other... and seem otherwise very happy. The bigger one is more brightly coloured with a kind of metallic pale blue tail, the other is duller and a greyish green with less pronounced spots, however has developed white marks, not exactly SPOTS like the others over the past few days (in bands across its back ) whilst the bigger one has turned quite yellow on its throat and sides. Can anyone help me? If I have two males I dont want to cause trouble by leaving them together. The smaller one measures 9 inches and the bigger one 10 inches. They were sold as a M/F pair but I'm not convinced. Do Females head bob? These first pics are of the larger one

And these are of the little one......

These are both males, the coloration on the top is a dead give-away, the femoral pores look pronounced which is malke also.

I keep them in a viv 3ft x 1.5 x 1.5, is this likely to cause probles with only one basking lamp? There are several branches for them to bask on but I've read they are very territorial.
