Subject: Why won't my sun turtle that I found eat?

My dad found a Sun turtle in the road and he said I could keep it. I got food 
for him and a home. But. he won't eat anything. He is only a little bigger than 
a quarter and he is a water turtle. I tried to give him food but he wouldn't 
take it, he just goes into his shell. I take him out two times a day for a half 
an hour to swim in a little pond.
Please answer quickly!!!
