Freshwater arowana fish are a highly sought-after species due to their unique appearance, large size, and interesting behavior. They are native to Southeast Asia and can grow up to 3 feet in length. Arowanas have elongated bodies covered in large scales that come in a variety of colors, including silver, green, and red. They are known for their hunting prowess and jumping ability, which makes them a popular addition to large, well-maintained aquariums. Arowanas require specific water conditions and a proper diet to thrive in captivity, making them a more advanced species to care for. Due to their popularity, they can be expensive and are sometimes subject to illegal poaching, which has led to conservation efforts to protect wild populations.
