When you grill fish you want to be sure to coat the grill with oil - this can be done with a rolled up paper towel and tongs. Drizzle oil on paper towel, hold with tongs and coat grill area you will be using.
Also, turn the fish once and make sure you have a large enough spatula. Watch the fish cook from the bottom up - when that cooked part has almost reached the center carefully turn it over. Once it almost reaches the center again remove it and tent it to finish the cooking process.
You can also marinate in a basic Asian style marinade - soy, dry sherry, sesame oil, spring onions, sesame seeds, brown sugar.
