Clean fish and wash it twice to thrice. Set aside.
In a wide mixing bowl, add red chilli, turmeric powder, coriander powder, lime juice and required salt. Sprinkle a little water to make a paste-like consistency.
Then add the fish and mix well.
Coat the masala on all sides of the fish and marinate for at least 30 mins.
Heat oil in a pan and fry the fish until the fish turns dark brown in colour.
