Turtle, Red-Eared Slider. Looks to be about "full grown". Tom is totally correct. This is an Aquatic Turtle. It basks or dries itself by using a ramp or stone. But whilst growing up they were in the Water 95% of the time. They are not meant for land unless its overgrown lawn by the lake/pond... While in the water, Gold Fish, Bloodworm Drops, Krill, Super Worms; depending on the Turtles appetite...
