My best guess would be Synodontis Ocellifer but they don't usually have so much colour through the fins.
Josh, I have to agree that if your "Peppered Cory" looks like the pic at the top of the thread, it ain't no Peppered Cory. They look way different. The big giveaway behaviour wise is if your catfish likes to spend a considerable amount of it's time upside down. Corys don't do that but Synodontis sure do.
