You should be fine then. It might be a good idea to keep a divider handy in case the fighting starts getting out of hand. Most importantly make sure they are close to the same size!

I agree... I had fathead minnows in w/ my oscar that it could easily have eaten, but they stayed in its tank for several months. It just depends on the individual fish I guess!i would agree with that suggestion.
and let me just say that you could always put any species of monster fish together in a tank, the real question is..... how long until one gets really beat up when they decide to kick the other's ass...i mean fins... or whatever![]()
It may work for now, but I'm betting the Jag will eventually want the entire tank to himself. A jag could rip a JD apart.
