Green snakes are normally considered to be difficult snakes to keep and those who are new to snake keeping hobby are often recommended to not start out with them. These snakes are not readily bred in captivity so usually what you see available in the pet trade are wild-caught specimens which do not easily adapt to a life in captivity, not to mention a life infested with internal and external parasites. They are also naturally shy animals and quite high-strung, thus making it necessary to restrict handling to the absolute minimum needed to ensure their care and well-being. In other words, these are definitely a "look, but don't touch" type of pet. However, while these snakes are challenging and often frustrating, they can also be rewarding when you finally hit on a successful method for keeping them.
