That's a native Florida gopher tortoise and protected. Very light in color, but I have seen some lighter ones as well.
Here is a picture I took last year of a Florida gopher tortoise that was very light in color.
I have another PVC cage from BoaMaster and it's just as nice as my AP cage. I had him add a 4 inch dam in the front as well for deeper substrate. It took 5 weeks to get. Their website appears to be experiencing some issues with images and I would call or email...
I know that @Tom uses Animal Plastics for his babies. I have one for my bearded dragon and they're great. It took 3 months for me to get mine, so order early. They may have got better with production. Highly recommended!
Beautiful and he looks great! Very similar growth to mine and same age. I’ve kept the humidity at 80+% and still have slight pyramiding. I do use coconut oil or shell conditioner a couple times per month now and he’s smoothing out a bit more. It definitely helps. Thanks for sharing.
Definitely go bigger. Start with 4ft x12ft or so. He needs a hiding place and ceramic water dish. Plant grass in a couple areas and let it grow as tall as it wants.
I agree with Yvonne above that the sides should be taller. A good rule of thumb is the sides should be as tall as the tortoise is...
