Place fish in a large non-reactive shallow dish and toss well with juice of 1 lime and 1 tsp salt. Refrigerate for 30 minutes.
Meanwhile, heat olive oil in a large heavy-based saucepan over medium heat. Cook onion for 3 minutes or until softened. Add capsicums, garlic and malagueta peppers and cook, stirring occasionally, for a further 5 minutes or until capsicum has softened. Stir in fish stock, tomatoes, coconut milk and dendê oil. Bring to the boil, then reduce heat to medium and cook for 20 minutes or until reduced by one-quarter.
Add fish and marinade and cook for a further 10 minutes or until fish is just cooked. Stir in remaining juice of 1 lime and season with salt. Scatter with coriander leaves and serve with steamed rice, if desired.
* Malagueta peppers are very hot chillies, available in jars from Latin food shops and selected delis.
* Dendê (palm) oil is available from South American and African food shops, and delis. It is used for its distinctive flavour, bright orange colour and ability to be heated to high temperatures. Substitute vegetable oil mixed with ½ tsp ground turmeric.
