Fish Suggestions for Large Oddball Community Tank
I've kept fish in the past and currently have a 10 and 20 gallon, but only recently decided to take the plunge into the world of big fish and bought a 120 gallon tank. Eventually, I'd like it to be an oddball community tank planted med/heavy with low and moderate light plants. So here's my question: Which fish? I know you guys hear this a lot, so let me be a bit more detailed.
I have a 120 gallon, 60"x18"x24" tank, filtered by two canister filters capable of filtering 525 gph each. The filters contain coarse, medium, and fine pads, bio balls, ceramic rings, Seachem Matrix stones, Seachem Purigen, and activated carbon. The tank is heated to 78 degrees by an inline heater, and monitored by a thermostat that will cut power should temperatures reach 80 degrees. The substrate is a 50/50 mix of Eco-Complete and fine rounded river rock/sand. A bubble wall is installed along the back of the tank. Eventually, I'd like to build up a wall of large, flat river slate, stacked up to make caves, ledges, and pass-throughs. It currently has two 48" Current USA Satellite+ LED lights. As for the water itself, it's a blend of mostly RO water with a touch of liquid rock from the tap. The goal is a KH of around 5 and pH of 7. It's been treated with Seachem Prime and Stability. It's been set up for over a month and currently houses seven giant danios, six Agassizi cory cats, and a Banjo catfish. I started with the smaller of the fish on my wanted list so they could grow out a bit before any of the bigger guys get introduced.
On to the fish! I've always liked the strange and unusual, and my taste in fish hasn't proven to be any different. That's why I decided on an oddball community tank, particularly with larger fish. Guppies, platys, and swordtails are cool, but for this one I want the kind of fish that when people look at the tank they think, "What the heck is that?" I've made a list of some of the fish I've found so far that I like, and I'd like to get more suggestions from you guys of interesting fish to make a balanced tank of upper, middle, and lower level swimmers. There are a few criteria, though.
Nothing under 3" adult size
Won't tear up/eat plants
Won't tear up/eat tankmates
Are peaceful in a community setting
With that in mind, I'd also appreciate any feedback you guys have on some of the fish I've thought about adding.

Columbian Shark/Jordan's Catfish (Debated whether fresh or brackish)
Discus (I've heard angels have a disease that kills discus? Info on that would be nice)
African Butterfly Fish
