🐟 Sailfin Marbled Catfish – (Leiarius pictus) – Large South American Catfish for Sale

The Sailfin Marbled Catfish (Leiarius pictus) is a large, beautifully patterned predatory catfish native to the Amazon and Orinoco River basins in South America. Recognized for its elongated body, striking marbled markings, and tall dorsal fin, this species is both a powerful swimmer and an active nighttime predator.
