Sapphire Betta Fish, or Betta Splendens, are a colorful and vibrant type of freshwater aquarium fish. They typically have a sapphire-blue body with strong light-blue to black fins, making them a popular choice for aquarium owners. The fish is known to be very hardy and easy to care for, requiring weekly water changes and a variety of live food, such as insect larvae or tiny fish. Commonly they are kept alone in a tank due to their territorial nature, though they can be housed with compatible tank mates.
