The Blue Mustard Betta, also known as the Siamese Fighting Fish, is a stunning and popular freshwater fish that will add a touch of vibrancy to any aquarium. Originating from Southeast Asia, these fish are highly sought after for their striking coloration and unique personalities.


To keep your Blue Mustard Betta happy and healthy, it's important to provide them with a tank that is at least 5 gallons in size. These fish can grow up to 3 inches in length, so they require enough space to swim and explore. They are carnivores and thrive on a diet of high-quality betta pellets and occasional live or frozen foods.


The Blue Mustard Betta has a bright blue body with a mustard yellow head and fins, making for a truly stunning and unique appearance.


Male bettas are known for their aggressive behavior, and the Blue Mustard Betta Male is no exception. They should be kept alone in a tank, as they may attack other fish, including other bettas.
