I have kept turtles for many years. I have an edge and a yellow throat. I especially like grass turtles. I have Brazil, and my mother is taking care of them.
I know turtles very well.
Maybe you have been feeding the wrong amount, which will lead to too fast growth, too wide growth line and dim color.
Feed once every 2-3 days. It's enough to feed your head every time. You can put some live fish and shrimp in the container for raising soft-shelled turtle, let it catch and eat by itself, cultivate wildness, exercise more, and not be bloated or obese.
As long as you put it in shallow water in a container and put it in a dark and ventilated place, don't wake it up except for changing the water. Don't think the sun is good. Give it some sunshine. The tortoise can't wake up during hibernation. If it stays awake, it will keep moving, consume energy in the body, can't eat, and eventually lead to death.
It doesn't matter once in a while, hehe, as long as you are healthy.
Well, if you raise turtles wholeheartedly and care about them all day, then there is no point in raising turtles. Hehe, raising turtles is just to relax, isn't that a burden? Hmm. How interesting
If you still don't understand, keep asking me and answer in time!
