Heh, I'd like to see that matchup. Unless outnumbered, the Jag can hold his/her own. I did get the pair I mentioned earlier, and the little 5" female was putting my 12" Midas in the corner. Of course, I don't condone fish fighting. I placed a nice, secure divider in my tank.
Jags probably rank in the top 5 predatory fish food chain, maybe #2 behind the wolf cichlid. Extremely smart! Usually quite calm unless something (including fingers) gets in their territory.
Jenn, I find it strange you of all people, would want to get rid of your Jag.
