Iridescent Shark Care Guide
Pangasianodon hypophthalmus · Freshwater Fish

What Iridescent Shark look like
Pangasianodon hypophthalmus is a large migratory catfish with a streamlined laterally compressed body, forked caudal fin, and small mouth set below the snout. Juveniles show the bright silver sheen that gives the species its common name, while adults become bulkier and darker.
Behavior & temperament
This is a fast, skittish, social open-water fish that grows far beyond normal aquarium size. It is peaceful with fish too large to swallow but can injure itself by crashing when startled. It belongs only in very large aquaria, indoor ponds, or public-aquarium systems with powerful filtration and open swimming space.
Diet & feeding
Iridescent Sharks are omnivorous river catfish. Juveniles take sinking pellets, chopped earthworms, bloodworms, shrimp, insects, and plant-based foods; adults need a large varied diet and should not be fed feeder fish.
Behind the name
Pangasianodon refers to the pangasiid catfish group; hypophthalmus means under-eye, referring to the low eye position.
Plan your tank
Check the numbers before you buy: tank volume, a stocking plan, cycle progress, water changes, and your ongoing care routine.
