Mystery Frog, please help!!

Okay here's the story on this little guy. My dad brought a plant home for my mom. He got it from work. His company had a booth at a covention and bought plants at home depo to make the booth look nice. They were bought in Chicago. Tonight which is night 2 of the plants being here, I see something move on the floor near the plant. My mom checks and it's a very tiny frog. I have worked at a pet store and I know a little not much but a little about frogs in my state (Maine) and I have never seen this kind before. He is exactly 1 inch in length. He is bronze ish looking with black horizontal stripes. He doesn't have webbed toes and looks to have pads like a tree frog. This picture is not very good he really would't stop moving and he's so small it's easy to lose him. I need to know what he is so I can house him properly. Thanks!!!
