I've been through the PDF care sheets and I still have questions. If there is no "preferred" habitat listed, should I just assume they're terrestrial? Is there a definitive list of arboreal species out there? And finally, almost every single species of PDF I've read about can be found up to at least a meter or two off the ground in the wild. Some go much, much higher. Given the size of our vivariums, wouldn't any PDF we keep utilize all parts of the enclosure, high or low?
