I just went to my neighbors house and they showed me their two leos. They wanted to know the sexes because they were getting eggs so I helped them out with that. My neighbors have had these geckos, one male and one female, ever since they were hatchlings and they have owned them for two years now. They have never provided a humid hide for them. They geckos look healthy, seem happy, and are reproducing. I also go to this one reptile store to buy mice for my snakes and they usually have around fifteen to twenty geckos on display with no humid hides. Those geckos seem to be doing well. Then my brother had a teacher a few years back(before I knew anything about leos and he didn't have a humid hide for him and that gecko was at least ten years old. So my question is do we have to provide a humid hide? And if we do what's the purpose of it? I have a humid hide for my gecko I am just curious if they are truly needed or not.
