Swedish Fish are colored a deep red, but there are no real answers regarding the candy's specific flavor. However, some believe that it’s probably lingonberry-flavored.
A lingonberry is a small, bright red berry that is a close relative of cranberries and blueberries. It is tart, slightly sweet, and acidic, commonly sweetened before eating.
The flavor comparison is partly speculation, but those who know the taste of lingonberries feel the flavors match up as the red fish candies have a similar flavor profile.
Americans who are more familiar with cherries than lingonberries might swear that Swedish Fish taste cherry-flavored. In the end, it could just be a mix of different berries.
