Nevermind - I seen that it is a redfoot! Excellent choice (I have four)! How old?
There is some dispute about the UVB - some keepers do not use any artificial UVB lighting (depending instead on vitamin D3 supplements and making sure your CRI, warmth and lumen are excellent).
I use a flood UV Heat lamp during the day - and a night bulb at night for extra warmth. My two older one (~ 6 1/2 months and 1 year) go outside during the day, but the hatchlings (1 month) can overheat quite quickly.
Mike Pingleton's book, "Practical Care and Maintenance of the Redfoot Tortoise" - is a MUST have. It's available at Carapace Press (and maybe Amazon ?? Chapters ???) The Tortoise Trust website is excellent. And Yahoo has a redfoot list.
If you have any questions - feel free to e-mail me!
Love these guys!
