Corys are one of the best substrate catfish; they will eat fry (and eggs obviously) of other fish, but not mature fish even if small (under 1 inch). [BTW, a 4.5 inch fish is not what I would call "smallish.";-)]
Another peaceful catfish is the Whiptail, Rineloricaria parva in our profiles, the original or the red lizard variant. Same as the corys, only likely to eat eggs and new fry.
