Originating from Southeast Asia, particularly Thailand, Cambodia, and Vietnam, Betta fish were historically found in shallow waters such as rice paddies, canals, and floodplains. Over time, selective breeding has transformed the wild Betta into a dazzling array of color morphs, with the royal blue variant standing out for its rich, metallic tone. Unlike lighter blue varieties, royal blue bettas display a darker, more saturated color that often appears to glow under proper lighting.

Caring for a Royal Blue Betta Fish requires attention to water quality and environment. A minimum tank size of 5 gallons is recommended to provide adequate swimming space and stable water parameters. Water temperature should be maintained between 24–28°C (75–82°F), as bettas are tropical fish. A gentle filtration system is ideal, as strong currents can stress them due to their long fins.

Decorating the tank with live plants, driftwood, and hiding spots can enhance the betta’s well-being. Aquatic plants such as Anubias, Java Fern, and floating plants are excellent choices, as they mimic the fish’s natural habitat and provide resting areas near the surface. Additionally, bettas are labyrinth fish, meaning they can breathe atmospheric air, so access to the water surface is essential.
