Funny i notice jungles morseo than other carpets like to rest their necks against the glass and walls and i used to think RTI all the time after having one animal with it and knowing the symptoms...i think the best lizard to try and see on a tree or background would be a leaftail,they're amazing animals and have perfect camoflage....
Also that's probably a good sign of a healthy animal not being stressed and comffortable to it's surroundings being out in the open without a worry!
