Obviously this works with any fish that's good fried, which is most of them. Avoid oily fish like mackerel or bluefish or herring, and I really don't this this is an ideal recipe for salmon or trout. But other than that, go for it. The accompaniments to the tacos are also up to you. What's in this recipe are what I like with fish tacos, but regular salsa works, as would chopped tomato, and lots of people like to mix chipotles in adobo with mayonnaise and drizzle that on top.
