Both Jin Dong and Xijin belong to the genus Scarab. Whether the scarab eats depends on the ambient temperature. If the ambient temperature is below 22 degrees, its appetite is relatively poor, and if it is above 25 degrees, its appetite is relatively normal. Then there is another factor that will directly lead to the tortoise's poor appetite, and that is sunshine. Turtles like drying their backs very much. On sunny days, they will be very willing to eat more, because turtles are warm animals, they need to digest food by the heat of sunlight and synthesize calcium by UVB in sunlight. Beginner turtles might as well be hungry 1 week before feeding, which will help turtles adapt to the environment faster and avoid gastroenteritis caused by stress reaction after entering a new environment.
