Reason 2: Hibernation. It is impossible in the present environment.
Reason three: partial eclipse. What are you feeding? I used to feed it live fish and bought it in Zhuhai. Gongbei pet street sells a lot, I hope it doesn't like it, because it can't afford it. You can also give vegetables and meat. Shrimp, earthworm, all these damn things are for him.
Reason 4: Brazilian tortoise won't die if it doesn't eat for half a month. It may be in a bad mood. It is suggested to let it go out to play for a while, or take it outdoors to bask in the sun, but don't toss. People don't eat anything and want to beat them to death. Often bask in the sun. It is normal for turtles to stay in the dark for five months without eating. People hibernate.
Reason 5: Did the little one touch something oily?
Reason 6: Worst case, getting sick.
