Fish Tacos

I had my mind set on fish tacos so I went on a recipe search and found this one at the top of the returns Google sent me. They were prettier than mine but I plead lack of colorful ingredients. What really caught my eye was the sauce:  1/2 cup sour cream, 1/3 cup Mayo, 2 Tbsp lime juice, and 1 tsp garlic powder. I had all of that and it sounded good.
