- The Malaco company developed Swedish Fish in the 1960s, specifically for export to North America.
- The original Swedish Fish was red, and the flavor was unique to the candy. Later, other colors and flavors were introduced, including yellow (lemon), green (lime), purple (grape) and orange.
- For the U.S. market, the candy is named "Swedish Fish" because it originated from Sweden. In Sweden, the candy is called "pastellfiskar" (literally, "pale fish").
- Swedish Fish do not contain gelatin.
- Swedish Fish also come in an assortment with other shapes, including a starfish, puffer fish, whale, sea horse and dolphin.
- The black variety of Swedish Fish has a salty flavor.
