Place the vinegar, sugar, habanero and ginger in a medium saucepan and cook over high heat until reduced to 1 1/2 cups, stirring occasionally. If the sauce becomes too thick, thin with a little bit of water.
Strain the sauce through a strainer into a bowl, stir in the red and yellow peppers, poblano, mint, Thai basil, cilantro and season with salt, to taste.
For the fish:
Heat the grill over high heat.
Season the cavity of the fish with salt and pepper. Brush the fish with oil on both sides and season with salt and pepper. Grill for 4 to 5 minutes on 1 side. Turn the grill down to medium and cook for another 6 to 7 minutes with the grill hood closed. Remove to a platter and immediately drizzle with the sauce. Garnish with Thai basil and cilantro.
