What is the 'center piece' of your tank?

I guess the featherfin syno would hold that honor presently. It's grown quite large... at least 6-7 inches. We've been toying with the idea of adding another centerpiece fish, though... something that's actually visible during the day. This thread has given me some interesting ideas.
 
My centerpieces in my 55 are all 3 of my discus, and my apistos are pretty showy too.
In the 45 gallon, my centerpiece fish are the 2 pearl gouramis that I recently bought.
I also have a 10 with a pretty blue female betta. This tank was supposed to be taken down, but she couldn't hack it in the 45 with the other betta girls. That's ok though, at least I had another tank already set up that she could move into.
I don't really have a centerpiece in my 75. I have a large gold severum, 2 large parrot cichlids, and a big nasty firemouth.:)Even my little dwarf green pike is a showoff in there. And before the stocking police jump in, no, I do not plan on buying a bigger tank for them. They have plenty of room. :)
I only have a yellow clown goby in my 2.5 pico reef, so he's my centerpiece by default in there.
I still have a long way to go on my 15 nano reef, but I do have a sweet sixline wrasse in there now.:)
 
In my goldfish tank, the centerpiece would be my one calico ryukin, which always commands the center of the tank.

All my other tanks are species tanks, so theres no centerpiece really.
 
The center piece of my 29 is my black lace angel "Seraphim". She's (he, whatever) is absolutley gorgeous, and everytime someone looks at that tank, that's the only fish they really notice!
 
See Avatar. He goes by Gourami, Dwarf, Piggy and The Beast. I have to keep an eye on him, he definitely "follows" the smaller neons and Otos... and even though he's had a small mouth deformity since the 4th week I've had him, he's really great. Gorgeous and great personality. (And the result is that my neons school really well. *lol*)

Originally I had carefully chosen the Indian name Sanja because of it's meaning/origin... but after Sanjaya ruined it, and I lost my first gourami, I think I am scared to actually name a fish, should it die on me. :(

Oh I know he's just a dwarf gourami, but I love them. If you can keep them alive, they're great. Something about their color/pattern, you never get tired of looking at him.

(Although I have to say, my Otos will steal my eye every time!)

Also, this is my dream tank with my dream centerpiece fish. No really, I hold no delusions of grandeur about upgrading beyond my 12g. The only thing I would like in addition, is a 5g Betta tank. Alas it's not to be. *lol* But I couldn't be happier than with my tiny chunk of paradise.
 
Have a pair of firemouths as my centrepieces atm:


And if I had the space and money, probably a pair of these:
