Tastiest fish in the world

I have this fish in mind that I eat twice a week, because it is really, really so tasty! But I do not know its name. It has... A flat body, silver colour even when cooked. Most people eat it steamed, because a fried version of it won't be as nice. It is expensive, not the kind of fish you eat every day. It can be considered a chinese dish. I just don't know its name.

I don't know that fish but my own choice of the tastiest fish of all fishes would be Titus, I really like the fish because of its fully fleshed out body and smoothness of the skin, there's only little bone in it and and cooking it really gives soup an extra oil. It's so sweet.
