Best way to cook fish?

I’ve gotten pretty handy at cooking steak, poultry, and pork, but have never tried cooking fish.

I have a pair of Mahi steaks I plan on cooking tomorrow – pointers? Recipe suggestions? Anything I should know about cooking fish that’s different from cooking dry land meats?
depends very much on the fish (I am no expert either, but based on my successes/failures).

first off, don’t keep it long or its going to get funky–i tend to cook it the day i buy it. likewise for leftovers–don’t plan on having any.
