Varanus panoptes horni, to be exact.
We bought 2.1, and have the 1.1 bonded pair set up in the large enclosure. The pictures don't show the enclosure well, perhaps some of you remember seeing pictures of it when it was set up for other monitors.
I didn't take many pictures of them just yet, they didn't seem to mind the ones I did take however.
They've been busy exploring, digging and climbing. I was afraid they wouldn't make use of the vertical height, but they have been so far (to bask)
