for the tank at the business you wont get anything more beautiful than asian arowanas, it would be hard to set up some sort of perpetual feeder colony in any tank, as you mentioned, because in a tank the parents and babies have no where to hide/ run away to. (unless you set up another set of tanks for fry raising)
im partial to clown knifes too, graceful and primarliy active at night, so you could light the tank with moonlights and the affect in the club would be amazing
