The tortoise is sick, doesn't like to eat, and its forelimbs are swollen. What should I do if I pull white shit?

It seems to be a digestive system problem, enteritis, right? You can soak oxytetracycline. The water temperature is below 20 degrees. Do you feed much? It is suggested that the turtle be heated. The water temperature should be kept at 25℃, and it can gradually rise to 28℃ these days. When it is ready, it will slowly cool down. Don't fall off once, pay attention to the temperature difference, and give the tortoise more sunshine. If it really doesn't work, it should be at least once a week for at least half an hour. Preferably a director. Never take it outside to bask in the sun.
