The Pangasius Catfish (Pangasius sutchi), also known as the Iridescent Shark, is a powerhouse addition to exceptionally large freshwater systems, blending high-impact aesthetics with essential utility. Featuring a sleek, silver-to-charcoal body and a distinctive shark-like silhouette, this active swimmer is a master of the "open water" era of fish keeping—serving as a natural biological focal point for the mid-water column. It is a dedicated and energetic inhabitant, making it a functional cornerstone of a massive freshwater ecosystem.
This hardy catfish thrives in established systems with massive horizontal swimming space and robust filtration. While generally peaceful, its bold personality and rapid growth rate mean it is best housed with other large, active tank mates in specialized or public-scale aquaria. To ensure long-term health, provide a varied diet of high-quality sinking pellets, frozen meaty foods, and occasional vegetable matter. Ensure your aquarium is well-covered and free of sharp decor, as these powerful swimmers are highly active and can be easily startled, leading to rapid bursts of movement.
Note: Images shown are stock images and not the actual fish you will receive.

Temperament: Peaceful (but active)
Minimum Tank Size: 300+ Gallons

The Pangasius Catfish is a strategic choice for hobbyists managing "mega-tank" setups who desire constant movement. Its specialized, shimmering skin and constant cruising add a layer of kinetic energy to the water column that few other large-scale species can match. In the context of large-format fish keeping, it is widely considered an essential "display species" for those with the space to accommodate its significant size. For maximum success, provide an environment with high-capacity filtration and stable water parameters to facilitate its natural vitality and growth.
We’ve dialed in the logistics for national Overnight Delivery to ensure your livestock arrives in peak condition. Every order is packed using professional-grade insulation and climate-contingent heat or ice packs, designed to maintain stable temperatures throughout the journey. We handle the technical side of the move so you can focus on the acclimation. Our protocol is built on getting these fish from the facility to your tank with zero compromise on health or vitality.
