I've kept many Jags over the years(most were rescues) and they were all aggressive but tankmates will be fine when they are chosen wisely. In my opinion I would look for something uncommon, there are hundreds of options to choose from and fish like RD's, JD's, GT's are so common and boring. With options like Festae, Trimacs, and RTM's available there are so many better looking fish than the common drab found at Petsmart and such.
