Butterfly the bangus (slice from the top) and the place it inside a large re-sealable plastic bag.

Pour the vinegar mixture in the bag and then let all the air out. Seal the bag and refrigerate overnight.

Remove the fish from the bag and let the liquid drip.

Heat the cooking oil in a pan. Once the oil gets hot, fry the fish in medium heat until one side gets crisp. Turn it over and repeat the process on the other side.
