This is Archies house he's a Hermann, do you think theres anything else I could add to it to make it better for him? It's a 6 ft bookcase turned into a tortoise enclosure so there's plenty of room for him also I'm not keen on the wood chippings I've got what substrate do other people use for theirs? Thanks Ps I do give hin water I'd just cleaned him out that's why it's empty
