I am moved by your dilemma and know exactly what you mean.  I only keep a 28 gallon with nano fish in it who all get along.  The other half of Pier Pressure wanted to go bigger, but when I showed him those big fish in the petstores he agreed it would be a bad thing to do as we would both be bothered by the "pacing".  Reminds me of a lion in a cage that is too small at the zoo, and I cannot see ever being happy watching a big fish who should have been left alone in the ocean.  However, the fish would probably be better off in your big tank than being sold to a newbie who thinks he would fit good in a 55 or some other such nonsense.
