What to feed my (soon to come) red-eared slider

I know they enjoy the pellets that include dried shrimp and whatnot. But I want to give my (soon to be) baby RES some fun with the hunt. I've heard of feeder fish, but have also read of people feeding them baby frogs and guppies. I'm just wondering about what fishes to feed them, I think I have everything else in perspective.

Red eared sliders need a diet that is a mixture of animal and plant material. However, young red eared sliders eat more animal protein so babies are started off on a diet that is more on the carnivorous side. It is still a good idea to offer vegetation to young turtles although they may not really start eating it until they get older (offering it early on at least makes it less likely they will shy away from trying it as they age). For adult red eared sliders, vegetation should make up a significant part of the diet.

Packaged Turtle Diets and Red Eared Sliders

Commercial pellets are fairly nutritious and are certainly convenient, and are beneficial since they contain a good mix of vitamins and minerals. However, as the saying goes, "variety is the spice of life." Offering a wide variety of foods is better than solely feeding a commercial turtle pellet as a variety of fresh food offers a wider range of nutrients in different forms (which may even be absorbed better when fed in the natural state).

As well, feeding a variety of items is more stimulating to the turtle. Live prey items are especially enriching, as they give turtles an opportunity to exercise by hunting as they would in the wild. Generally, I would recommend limiting pellets to about 25% of the diet, making up the rest with items from the list below.
