Catfish can. But they can grow to be quite big so they probably wont be such a good idea. Any fish bigger than the turtle wont get eaten by it, but the turtle may attack it. But when I got my turtle he was in a tank with quite a few small catfish and they didnt seem to bother each other.
I heard that goldfish can live with turtles but mostly the yellow bellied turtle, but make sure that the goldfish is bigger than the turtle and you never know as the turtle and fish get older they might become friends!
