So I have a whites tree frog and a sub adult standing's day gecko. The tree frog is a male and is just shy of 3 inches, and the gecko is a female, and is about 7 1/2 inches. My question is if I can house these two together, it would really save me some space. The tree frog is small enough that I don't run the risk of him eating the gecko, and day geckos generally don't eat things larger than there heads. I wouldn't think the two would fight being completely unrelated species, and different sexes. One being nocturnal and the other being diurnal would limit how much they interact with each other, the frog is basically just a blob on the side of the glass during the day, and the gecko hides at night. They both have almost Identical care requirements, and I have a pretty big enclosure I would house them in. I don't know, it seems fine to me. I know cohabitation is a pretty touchy subject in the reptile/amphibian community, but I would like to hear other people's thoughts.
