Male green sunfish will tear everything apart. They'll kill things just to kill them, not even to eat. Females aren't as bad, but it's very difficult to sex them before they're adults, and adults don't adapt well to aquarium life.
If they're legal in your area, warmouths can be caught by dangling bait around lurking spots. Overhanging branches, clumps of water-weed, logs, etc. Try to get one under 4" long. Under 3" is ideal. They have pretty big mouths, so your bait doesn't need to be that small. Gulp minnow lures can work well, or just some bacon fat. Anything that wiggles is also a decent bet. You're after a sit-and-wait predator, and they aren't all that difficult to catch. The issue is just finding one.
I caught mine purely by accident, while fishing around a big clump of plants. He took on a bait that was far too large for any longear his size.
You're basically fishing for a leaffish, is the idea.
