Are there any catfish in the 3-5" range?

North American Madtoms mostly grow to the 3" to 5" range. Very cool fish, they look like mini channel and flathead catfish.
 
The Synodontis petricola only gets to around 4" and they're gorgeous. I got one awhile back and am waiting to get more. Here's a picture of one. They remind me of Cory cats, I just love mine.

At least one species of bumblebee catfish is in that size range, not sure which one it is though.
Some of the Doradidae (aka "talking" catfish) as well; striped or spotted raphaels are the most commonly available species.
Banjo cats also come to mind, along with the ones already mentioned above.
Synodontis nigriventris, the common upside-down catfish, max out around 4".
Synodontis are the most likely to be visible by day, at least if kept in a group.
