What is a Royal Blue Betta Fish

Royal blue betta fish is a rare and beautiful variety of betta fish characterized by its brilliant, metallic blue color. The blue color in these fish results from a genetic mutation and can vary in intensity from light blue to a deep, almost navy shade. Royal blue betta fish are unique from other betta fish in that their blue color is uniform across their entire body and does not fade or change with age.

Origin and History of Royal Blue Betta Fish

Betta fish are native to Southeast Asia, specifically in the countries of Thailand, Cambodia, and Vietnam. Westerners first discovered them in the late 1800s, and they were originally used in fighting competitions in Thailand. Over time, breeders began to focus on enhancing the color and beauty of betta fish, resulting in the development of many different color varieties, including the royal blue betta fish.
