Well, I'm going to get a crested gecko or two in December, and would like to know how to properly set up the cage. i have a 21x21x18 exoterra glass terrarium and have a few questions. Would it be ok to have UVB lightbulbs i nthe enclosure? IS it a good idea to put moss in the setup? because the dead kind keeps in bacteria. Would it also be a good idea to keep a water dish in the setup? What kind of bedding should i use? I've used bark before but it can cause impaction and coconut fibers can casue eye infections.
