The Sun Catfish, scientifically known as Horabagrus brachysoma, is a freshwater catfish native to southwestern India. It's characterized by its yellowish-brown coloration, a large black spot behind the head, and a light-colored belly. They are known for their distinctive "sunburst" markings, especially when young, which fade as they mature. Sun catfish are nocturnal, growing to a considerable size (up to 18 inches) and are not suitable for small community tanks.
