One of my favorite display herps of all time - rough green snake. Their small size and slender build make it possible to create an elaborate, planted vivarium without fear of the landscape getting destroyed. Being diurnal and arboreal, it's easier to show them off as they are often out and about - though sometimes it takes a bit of searching in heavily planted setups(Waldo makes an appropriate name for these little suckers). Most fun of all, when you want a snake that will perform like few serpents can - drop some bugs in the enclosure and enjoy the show. Their small size and general flightiness make them poor handlers. They're not aggressive at all, you just get the feeling they'd rather be gliding through some bushes than stuck in human hands. All in all, very graceful creatures that make amazing display subjects.
