It's not a Brazilian turtle, it's a kind of doughnut turtle and water turtle, but it doesn't need too deep water, so it's best to bask in the sun every day, so there should be a terrace, because I don't know what environment you are raising, so I won't say much. Feed small fish and shrimp, all kinds of meat and animal offal, and try not to be too big. The amount of each feeding can be the size of its head. Turtles are slow-digesting animals, so there is no need to feed them every day, every other day and once every two or three days. Change the water when it stinks. If tap water is used, it is best to use it in the sun for two days or in the shade for a few days. Don't bring it out directly from the tap. It is suggested to change the water, that is, half of the old water should be left every time the water is changed. It is best to use tools to pump out the dirty water at the bottom. Turtles are cold-blooded, sensitive to temperature, and the temperature difference should not be too large, otherwise they will catch a cold and die of pneumonia. When the temperature is around 20 degrees, activities will be reduced and food intake will be reduced. /kloc-Don't feed above 0/0 degrees. Rest with clear water, and then go into hibernation if it is colder. Just put some clean sand in it when you hibernate, put it in a quiet place and wake up next year. Winter in the north is too cold. Hibernation is not recommended. It will freeze to death. Please heat it up.
