Sounds like you have a synodontis peppered corys are one of the smaller cory species.
More than 10 years
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.
