I got him at Big Als a cpl years ago and he does not look like my Eupterus that I bought him with. It is much larger with a very different spot pattern. But the spots run perfectly in line right down the body, so I'm not sure what he is. It was in a tank with Eupterus. I'm not sure if you can tell by these pics, he is very camera shy, but I snapped a pic of the Euterus for comparison.
Cheers for the help.

Synodontis ocellifer maybe?

Looks just like my ocellifers, which also came from Big Al's. Tres Bien!
