I've had my female GTP for over 5 years and although they do require more care, humidity, proper perching, temps etc. I wouldn't really say they are not for beginners. They can be snippy but as previously stated it helps to make sure they are aware of what is approaching them before you stick your hand in their enclosure. Take it slow and give them time to adjust. Watch for the tongue, slow long flicks seem more investigatory, short quick more of a hunting mode. They can literally go for being still Yo striking within seconds, this really goes for any snake but gtps can be aggressive.

As babies, not a good idea to handle them too much, as stated before their tails are very fragile as are their bodies really. Then are built light and thin. Sub adults are no problem, I take mine out probably once a week without issue to clean her enclosure etc. Let her loose for a bit

I will say there have been times at dawn when feeding, her feeding response is very aggressive, she strikes fast and hard, I wouldn't want her to snag me that's for sure. Overall, it's a beautiful animal but deserves respect for what they are, ball pythons they are not. Hope this helps
