Actually, if you are ok with an aggressiv fish, look at a Sohal. I think they are one of the most beautiful.
I have one, and it is the showpiece of my tank. Blue, White, Orange, with glowing translucent blue highlights and cool eyes.
They can be aggressive, in my case, mine is very friendly... But in general a bully. Reason I say take a look at these is because not many people have them, so you can be unique like me! I am special, so very very special.... HEHE
