do you mean red footed?
if so, congrats to your son, they're stunning!
i don't know a huge amount about tort care, these sheets seems to explain housing quite well
Red Footed Tortoises - Care of Red Foot Tortoises
Red-foot Tortoise Care - Darrell Senneke and Chris Tabaka DVM

also, i don't think you are suposed to keep torts in vivariums because of the poor ventilation, if they are inside they are suposed to be housed on tortoise tables.. but i think these guys need humidity so i'm not sure.. sorry
