My redfoot tortoise is about 8 months old and has stopped eating for the past couple days. He was already emaciated when I got him 5 months ago but he was getting better. I've tried a variety of his most favorite foods and nothing is working, he might nudge it with his nose for a bit but that's it. He is also not opening his eyes. I read something awhile ago about the UV lights being to bright but I changed them and nothing has been solved. Please help.
