I doubt it. Keeping one of each is a bit cruel. The fish will feel threatened because they lack companions. Remember, only keeping 1 ram is bad enough because it is a pair fish. When you're dealing with harem fish like some apistos, you have to think of them like neons or other schooling fish. Besides, you won't get any color out of them becaue they have no mates to impress. I suggest you pick one, maybe two, species and work from there. You could use plants, rocks, and other obsturctions to divide the tank in two, sort of what you would do with a tang. African tank.
