Hello

This is my first post. Hope somebody is out there to help me.

My garter is not eating. It´s been 17 days. Last time he ate he had four live fish, gyppy size. I´ve offered him everything from dead fish, earthworms to live fish. He seems aware of the food but doesn´t seem interested. I´ve had him for a little over a month now and I´ve feed him earthworms and live fish until now. But he never eats much. He´s a young snake, less than a year old. I try to make sure that the food is easy for him to swallow when I serve it. I´m not sure I´m ready to force feed him yet. He seems in good health. I see him every day climbing the branches in my terrarium.

Should I be worried ??? How long can he go without eating.
