I had been searching for a tank mate for the Jags and due to their aggression level it has been near impossible. Upon talking to a few local Jag owners, a couple had mentioned they had heard of Piranhas being suitable. I looked into it further and had indeed found a few online references to confirm this coupling. The Jags will still be the dominant ones in the tank will, but they will apparently co-habitate. I am still keeping a very close eye on the situation and so far, so good. As I mentioned previously, I don't want harm to come to either, and if aggression levels do increase there will definately be a seperation in the future. Again, I welcome any ones input on this scenario.
Thanks!
