ok, so im getting a box turtle from a petstore thats like alittle personally owned one. The guy is relatively knowledgable but i fell in love with this little box turtle, and its a good price and captive bred, he didnt actually say what type of box turtle so i gotta figure that out still. He looks healthy and all i had a good long look at him. but i have a few questions: what is the best/ easiest accesibly/ least messy substrate for a boxxy? also could someone let me know what all i need to set him up good and healthily
