This solitary freshwater fish is a Betta fish (Betta splendens), often called a Siamese fighting fish. As a biologist, I'm captivated by the beauty and behavioral complexity of this species. This individual has a beautiful, pale yellow and white body with a flowing, feathery tail and fins. Its delicate, translucent fins shimmer with subtle hints of blue and green, adding to its ethereal appearance. Betta fish are native to the rice paddies and shallow waters of Southeast Asia. They are renowned for the male's aggressive territorial behavior, which is why they are often kept alone in aquariums. Their intricate finnage is the result of selective breeding for different shapes and colors, making them one of the most visually stunning and widely recognized species in the aquarium trade.
