What kind of frog do I have?

Definitely a fire belly toad... If you have a local Pet smart or other pet stores they usually have them for sale... When I went to pet smart a couple of days ago they had a really good variety... the green on their backs were vibrant and the orange bellies looked really good. Make sure that you have a lot of water and land too... I did half and half in my tank. That way the frog can get in and out of the water as it pleases....
