I have posted more info and picturesWe're going to need a lot more information.
A tortoise wont eat if it's too cold. Too hot. Too stressed or if its sick.
Can you tell us about your enclosure. The substrate. The light types. The heating type. And your temperatures are humidity levels.
Also, what are you feeding?
Maybe also a photo of the tortoise.
Thanks I posted more infopictures, pictures, pictures.
Can we see enclosure set up, the tortoise, living conditions, where his environment is?
New tortoises can be prone to stress of change. So do not be surprised if this is that. How long has it been since you recieved your tortoise?
