For the fish soup, cut the boned fish fillets into bite-sized pieces and the zucchini into crescent-shaped slices about 1 cm thick.
Cut the spring onions and chili peppers diagonally into 1 cm pieces each. Finely chop the garlic.
Bring the water or fish stock to a boil in a saucepan. Add the fish as well as the zucchini, chili and onions and boil everything for about 3-4 minutes. Now season with garlic, paprika powder, salt and bell pepper.
Pour the hot fish soup into warmed bowls and serve.
