Quick and Spicy fish curry

This is one of the easiest fish curries I have ever made. It just takes 10 minutes of preparation. I used tilapia fish for this preparation. I like to make it very spicy. After a long day at work, I like to eat this spicy fish with paij (rice soup, usually made with boiled rice).
What you will need:
1 small fish (cleaned and cut into 2" pieces)
1 tsp chilli powder (or more)
1/4 tsp turmeric powder
1 tsp ginger garlic paste
1 tbsp coriander powder
1 tsp cumin powder
1 tsp garam masala powder
2 tsp lemon juice
1 tbsp oil
salt to taste

How to prepare:
Mix all the powders and ginger garlic paste with 1/4 cup of water to make a paste.
Heat the oil. Add the paste and fry until the raw smell of the paste goes away.
Add the fish pieces and 1/4 cup of water. Cover and cook until the fish is done.
Turn the heat off and add the lemon juice.
