I found this little guy walking across a street in the city. I like in Tucson az. I showed a desert pet store guy and he said either a desert or sulcata tortoise. I'm thinking sulcata. Any rough idea on how old it is? That is a water bottle cap next to him for size reference. I got him a 20gal tank it came with 2 powersun bulbs one says 125w and 160w. I use the 125w. Also a 100w ceramic bulb and small heat mat for night. Idk if these are to strong or if they will work. I put some reptile bark and small dish for washer and a place for him to hide. How I went the inside to keep non it humid but how do you keep it humid in his hide area or does the humidity just go In there? I appreciate all the info and advise I can get.
