Tasty/Healthy Fish Recipes?

I'm a pescaterian (I only eat fish - no chicken, pork or beef) but I'm not very knowledgable about how to cook too many things. I'd finally mastered chicken and ground beef but then decided to give it all up

Does anyone have any good fish recipes (preferably low-carb)? If you could include info on how long things need to cook (on both sides), that would be really helpful. My kitchen skills are basic at best.

Thanks!
