I have two rough green snakes now and they are an awesome display snake. I have their tank set up with perches and vines and they climb all over.They are active most of the day and even when they are sitting still they strike poses...
The downside is I have been unable to find then captive bred and the wild caught ones at pet stores are very frail. I had one die and I felt awful. I avoid handling them now and I plan on getting a huge tank for them in a few weeks, with soil and a lot of plants and vine to climb on.
