Hi and welcome to you and Gru - he' s gorgeous!
Where are you located?
Is he a sulcata? (I'm not great at tort IDing )
- if he is you'll find this useful: http://www.tortoiseforum.org/threads/how-to-raise-a-healthy-sulcata-or-leopard-version-2-0.79895/
and there is also a good diet sheet in the Sulcata section too.
The Beginners Mistakes thread is great for helping to avoid pitfalls encountered by others (link below)
and the Enclosures thread is full of good ideas.
Looking forward to seeing more pics of Gru and his enclosure.
