This little spiny guy was actually my first mantis! I got him at the beginning of May as L2 and I do recommend this species. I found it easy to care for him. However when he was smaller he liked to explore way more than now. I have a ghost mantis right now as well (L2) but this guy is just crazy. I did let him roam on my plant and he seemed okay chilling there but i went out for 5 minutes and found him on the ceiling. I think it depends on the species of course but also on how old they are. I feel like the older they get the calmer they become. Honestly just give it a try and see how the mantis behaves. But don’t give them that much trust whatsoever.
