I'm actually a fan of unusual characins, which I keep in my overgrown 32 gallon (currently trying to source a poecilocharax weitzmani). However, I find the whole monster/predatory fish thing interesting. Nothing like watching an aimara lunge at something. For looks, I'd say peacock bass are my favourite. For personality, a catfish of some kind. Not that I'd have the money/space/time to put together a monster tank.
One question... has anyone taken a monster sized tank and just filled it with crazy numbers of little fish? That would make an cool display. Another idea I had was to take a big tank, fill it with guppies or something that breeds quickly, and then put in a small predator, like a leaf fish. The challenge would be to bring the tank to equilibrium, with the feeder fish reproducing at the exact rate they are predated upon.

Thanks for all the greetings everyone!
