Ok, getting really confused now! We have been keeping the viv at levels for what we assumed is a veiled, and he/she seems to be happy enough. We had just come back from picking her up at the vets so hence not the usual colours as a little unhappy. Had also had two calcium jabs. I wouldnt be happy either!

We put her in the viv, and she went straight down the bottom and started digging at the back of the ficus (made sure it was damp enough to hold itself) and has stayed there all night. can only see a coiled tail now. We have also put a large bucket with aquarium sand in which is also damp enough to hold itself.
With regards to the first tunnel, there were actually a few little holes dug right down to the bottom but were maybe 4cms. The actual tunnel was dug facing into the cage. she has never tried to get out of the cage since we had her. And does not like being handled!
Due to not liking attention, its hard to take pics, but as you mention the lump Juliers, do you see why we thought it was a male? Definately has bumps, but like i said, not as pronounced as the spur that was shown.
The chams relaxed colours are pale green, with pale yellow rectangles along the length of the body and white racing stripe down the side.
