I have 4 Jack Dempsey's (3 regular, 2 are female 1 male and 1 male EBJD) and 3 Texas with a Jag. The Jag chases my 1 female Dempsey and all 3 Texas. For me the funniest part with my Jag is how wide it flares it's gills when it's angry. I've only seen it (I'm sure it happens more than I see) nip at the fish a couple times. Mostly just chases though. You wouldn't be sorry getting yourself some Jags. Skittish when small, but they grow into some beautiful fish as well as entertaining. They will sometimes throw temper tantrums if you don't feed them what they want or like. I wish I had a 180 gallon tank and get a couple more to grow out and hope for a pair with the one I have.
