It depends on what kind of turtle it is. My son had a box turtle (land turtle) and it had a canned turtle food that we used to scoop out onto a lettuce leaf. The directions were on the can of food. We also gave him lettuce and peeled apple slices. We would put fresh servings of that in there every couple of days. We also looked at red-eared turtles(water turtle) and they eat gold fish and crickets. I think the clerk said they needed to be fed 2 or 3 times a week with that live food.
