the previous owner says he hasnt eatin in like 1 month or so is it still ok if he doesnt eat?

I dont know how old the pic is so I will try and post one but he looks healthy, and is very active when u hold him/her. He came with two half circle hut hides should I get a couple ceramic pots like i use for my bp for hides instead of the huts?

the guy says he is like 3 years old, is this to old to try and sex him/her?
