Fish are individuals, of course, and they're all a little different. In my limited experience longears are pretty peaceful with other fish species, but you may end up with a more aggressive individual. Like any sunfish the males can get nasty with their own kind, or similar looking species such as dollar sunfish.
There seem to be two schools of thought with limiting sunfish aggression: keep a low stocking density, especially of males, or keep a very high stocking density with a high proportion of males. The idea of the second one is that no one fish will be able to dominate the group, so they will all quit trying after a while. I've only tried the first method.
Warmouth are fun fish. They are sit-and-wait predators with huge mouths, so they may not be as ready to jump right into the feeding fray as other sunnies, but when they do decide to eat they will take huge items the other sunnies can't handle. In my experience juveniles adapt well to competing with other fish for food and will hold their own.
