The betta, also 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. Betta fish are often kept in aquariums and are appreciated for their beauty and unique personalities. These fish are territorial and can be aggressive, especially males, which is why they are often kept alone or in carefully monitored groups. Betta fish thrive in warm water and require a well-maintained environment to stay healthy. Proper care includes regular water changes and a balanced diet of high-quality fish food.
