Favorite Fish and Why?

My favorite so far is the severum. So graceful and aware of its surroundings, but mellow and laid back at the same time. I just started a new 75 gallon tank with an Oscar and Green Terror. The green terror seems to have a lot of personality, so my favorite might change in the near future.
 
Discus

For those interested in Discus, please start with a large aquarium - 55+ gallons for four fish maximum..
