Why did the turtle die suddenly? It’s so sad. Please help me figure it out!

First of all, let’s talk about Aman: The so-called temperature difference of pneumonia is very easy to get in spring, autumn and winter. It is not caused by the problem of water temperature but the temperature difference between water temperature and air temperature. Aquatic turtles also use their lungs to breathe. If the water temperature is high and the air temperature is low, there will be a temperature difference. The solution is to cap the container.

About turtle eggs: There are several possibilities

The first is caused by eating too much. This possibility is relatively small but possible.

Then the turtle gets stuck somewhere in the container, causing it to be unable to breathe for a long time, leading to suffocation. This way of death usually causes swelling all over the body.

Water quality and protein worms have nothing to do with the cause of death. Brazilian turtles are very adaptable and will not have any problems due to this. At most, it's just a supercilious problem, but it won't cause death.
