JD's become very aggressive and territorial even before they mature (hence the name). In a tank that size, which is a tad less than the recommended minimum for 1 JD he'd have to be the only fish in there. He may leave your plec alone, but keep an eye on the situation as he might start to resent its presence.

In their natural environment, JD's are surrounded by heavy vegetation, but it's not usually practical to give them plants in an aquarium as they will dig them up. For that reason, it's best to provide planty of hiding places - rockes, roots, bogwood etc.
