Set fish over hot side of grill and cook until bottom side is browned, about 5 minutes. Using a carving fork, insert tines between grill grate and under fish. Carefully attempt to lift fish from below; if it resists, allow to cook for 1 more minute and try again. When fish lifts easily from grill, turn onto other side and cook until an instant-read thermometer inserted in the thickest part registers 135u00b0F (57u00b0C), about 5 minutes longer. If skin begins to char before fish is cooked through, transfer fish to cooler side of grill to finish cooking. Let rest 5 minutes. While fish cooks, warm corn tortillas directly over hot side of grill, flipping them as soon as they start to char slightly and stacking them under a kitchen towel as they finish cooking in order to keep them moist.

Transfer fish to a serving platter and spoon scallion/cilantro mixture on top. Garnish with cucumber slices and lemon or lime wedges. Serve immediately with hot tortillas and cucumber pico de gallo. Diners should make their own tacos, picking the meat out of the fish and topping with pico de gallo and lime as they go.
