As my greenhouse nears completion, I'd like to do some research on a pet or a lizard that could do well in a high humidity environment. I spoke to my local lizard guy and he recommended house geckos. I looked them up, and they seem to be nocturnal, small, and overall not that interesting. I had dreams of a surly iguana with a designated branch that he hangs out on. Does anybody have a greenhouse pet that roams free? Any recommendations?
