Put a large saucepan on a medium heat with half of the vegetable oil. Add the curry paste and cook for 2 minutes.
Pour in the coconut milk and 200ml of water. Add the rice vinegar and bring to a gentle simmer.
Meanwhile, cook the sea bass. Season both sides of the fillets with salt. Put a non stick pan on a medium heat and add the rest of the oil. Cook the fillets skin side down for 5-7 minutes until golden brown, then flip and cook flesh side down for 1-2 minutes until cooked through.
Add the sugar snap peas and noodles to the broth - cook for 5 more minutes until softened. Stir in the chopped coriander.
To serve, ladle the soup into bowls, top with the sea bass and then scatter over the peanuts. Enjoy!
