I have a happy and healthy male veiled chameleon. Yesterday I transplanted a new hibiscus plant into the tank. I layered live moss to grow, and some sheet moss so he wouldnt bother with trying to be by the bottom. Mostly he seems to be up in the top, loving the plant. I also started using a fog machine to maintain a higher humidity while I'm away. When I came home today, I found a hole dug in the corner and him covered with dirt. His spurs on the heels shows he is male. I just don't understand why he would do that. He eats healthy, but surely prefers his worms to crickets. I wonder if changes due to fogger or new plant are the cause. I had a different plant in there before, and he never acted as such.
