Tiger Shovelnose Catfish

Pseudoplatystoma fasciatum is one of the most striking large freshwater fish in the world, its silver body crossed by bold black vertical bars reminiscent of a tiger. It inhabits large river channels and flooded forests across the Amazon and Orinoco drainages, where it preys on fish, crustaceans, and other aquatic prey.

In captivity, Tiger Shovelnose Catfish are active, powerful swimmers that require long tanks with very strong filtration. They are best kept at the upper end of their size range with tankmates too large to be predated. Water quality must be excellent as these fish are sensitive to elevated nitrates.

Their elongated, flattened snout is highly adapted for locating prey by touch and electroreception in murky water. Long barbels extend well beyond the head and should never be damaged by sharp décor. Despite their intimidating size, healthy individuals become relatively accustomed to their keeper and will learn feeding routines quickly.

Water: 22–28°C, pH 6.0–7.5, soft to moderately hard; nitrates must be kept below 20 ppm. Tank: Minimum 1500L, long footprint preferred; minimal décor to avoid barbel damage, powerful external filtration. Feeding: Carnivore; whole prawns, fish fillets, large cichlid/catfish sticks, frozen lancefish; avoid live feeders. Breeding: No documented captive breeding; wild spawning linked to seasonal floods. Compatibility: Keep with other very large South American fish; will eat anything smaller than roughly half its own body length.
