Giant Pangasius – Pangasius sanitwongsei | Impressive Large Fish with Shark-like Elegance

The Giant Pangasius (Pangasius sanitwongsei), also known as the Mekong Giant Catfish, is one of the largest and most impressive freshwater fish in Asia. Even as a juvenile, its streamlined body, powerful caudal fin, and majestic swimming style resemble a true shark. As it grows older, it develops a silvery-metallic body coloration and impressive size – a highlight for large aquariums and exhibition tanks.

The Pangasius sanitwongsei originates from the Mekong and Chao Phraya river systems in Southeast Asia. It is an extremely active, peaceful schooling fish, but it grows very quickly and can reach enormous sizes of over 2 meters.
