Hi my tortoise has a dry spot on his head and where his legs meet his body hes pretty skinny i feed him Dandelion Greens, Green Lettuce, Romaine Lettuce, Sometimes Tomato, Yellow Squash, Green Squash, Green Bean and then for fruit i feed him PineApple, Mango, Kiwi, Apple with no seeds sometimes, Pear and thats it im pretty limited at my local store but i add new things to his diet pretty often i have had him for about 3 months hes 4 to 5 years old i bought him from some people that rescued him and then didnt take really good care of him he didnt have very much warmth and his diet wasnt even relatively good all they were feeding him was tomato green lettuce and cat food so not very good but hes really active im gonna be building a tortoise table within a week to get rid of the aquarium and i keep the temp at about 80 on one side to 86 on the other i keep the humidity at about 70 and mix around his substate once a day im just worried about the dry spot [he had it when i got him] and his skinny legs when it goes up to meet the body is that normal for the legs to be like i feed him quite a bit is it lack in vitamins calcium protein diet? im just not sure thanks for any response also how should i clean his shell in the cracks cuz hes kinda dirty.
