Babies generally are not cage aggressive. If you handle it a lot as it grows it should help it not to become aggressive, but some (especially females) will become cage aggressive either way. Sometimes once they are out of their established territory they are fine. I have an adult male and female that were not handled much when they were young and I think they would bite my hand off if I just stuck it in their enclosures without being mindful and careful of them. I have another male that I raised from a hatchling and I handled him a lot and I can pretty much reach all around him and do whatever I need to do in his cage with him right there. It really just depends on the individual gecko, but if you get a gecko that is young and you handle it regularly you have a good chance of having a more friendly and calm adult.![]()
