A real mild tasting fish is orange roughy. I have baked this and it is good that way. I thaw the fish, lay on a sprayed pan, drizzle with melted butter, a dash of lemon juice, and a sprinkle of lemon pepper. Bake until just done at 350 degrees. If you chose to saute it, fish cooks very fast, about 10 minutes per inch of fish and over done will make it rubbery and not so tempting.
