Question

How long can a Red Ear Slider of any age live without eating?

Answer 1

They can go a week (summer) to a month (winter) comfortably. They can survive longer, of course.

Answer 2

I've owned about 5 red eared sliders over the years.  I hope you just can't get it to eat and that your not starving it on purpose.  If you can't get him to eat just put turtle food sticks in the water...they will dissolve and he will absorb the nutrients in through his shell and skin.
