It depends what's wrong with it! First course of action would be to take it to a vet!
The hotter side really depends on your gecko, some like it really hot (100 degrees Fahrenheit!) and some like it as cool as 75 degrees Fahrenheit. A good starting point is 78-88 degrees, if the gecko spends almost all of the time on the cool side it is too hot and you need to cool it down a bit and vice versa. So how do you heat your gecko's habitat?
Use a heat pad. These can be bought at any pet store that provides reptile supplies. These are one of the more expensive components of a gecko habitat, one suited for a 10 gallon cage can be as much as $25.
The heat pad should be about 1/3 as large as the whole surface area of the bottom of the terrarium. Make sure to read the directions to this product.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
