Betta Splendens, commonly known as the Siamese fighting fish, is a popular freshwater fish native to Southeast Asia. They are known for their vibrant colors and long, flowing fins, which make them a favorite among aquarium enthusiasts. Betta fish are typically kept in individual tanks due to their aggressive nature, especially males, who will fight each other if housed together. These fish thrive in warm water, ideally between 75°F and 80°F, and prefer a well-planted environment with hiding spots. Betta Splendens are also labyrinth fish, meaning they can breathe air from the surface, allowing them to survive in low-oxygen environments.
