Heat 1 tablespoon oil in a large pan to medium heat. Add the onion and jalapenos and cook for 5 minutes to soften.
Add the garlic and tomato paste and cook for 1 minute, stirring.
Stir in the seafood stock, El Yucateco Marisquera Red Seafood Habanero Hot Sauce, orange juice, Mexican oregano, and salt and pepper. Simmer the sauce for 20-30 minutes to let the flavors develop.
While the sauce is simmering, boil the noodles in a pot of salted water according to package directions, about 10 minutes.
Drain the noodles, but reserve 3/4 cup of the starchy pasta cooking water.
Heat 1 tablespoon vegetable oil in a large pan over medium-high heat. Season the scallops with salt and pepper, then sear the scallops for 1-2 minutes per side or until browned and cooked through. Remove the scallops and set aside onto a plate.
Season the shrimp with salt and pepper and cook for 3-4 minutes in the pan, or until pink and cooked through. Remove the shrimp to the plate with the scallops.
Add mussels to the pan with the reserved pasta water, and bring to a simmer. Cover and cook for 4-6 minutes or until mussels open up. Discard any unopened shells.
Add the shrimp, scallops, and mussels back to the pan along with the marisquera sauce and cooked pasta. Toss to combine and warm through.
Serve into bowls, garnish, and serve.
