Place the fish in a bowl and toss with 1/4 cup olive oil, the coriander, cumin and some salt and pepper. Toss in 1/4 cup cilantro and 1/4 cup parsley.
Saute the onions, garlic and serranos in a medium sauce pot with 1/4 cup olive oil until the onions are soft. Add the black beans including their liquid and bring to a simmer for 2 or 3 minutes. Remove from the heat and pour into a food processor and pulse until fairly smooth. Add the remaining parsley and cilantro, pulse, and place in a bowl.
Add the remaining oil to a saute pan over high heat and saute the marinated fish strips until opaque. Season with salt and pepper. Place a few spoonfuls of the black bean puree in the bottom crease of the shells, then add about 1 1/2 ounces of the cooked fish and 3 teaspoons pico de gallo to each shell. Serve with a lime wedge.
