Shovelnose Tiger Catfish

The Shovelnose Tiger Catfish is one of the most visually striking large catfish available in the freshwater aquarium hobby. Pseudoplatystoma tigrinum earns its common name from the bold, dark vertical bands that stripe its elongated silver body — a pattern reminiscent of a tiger's coat and unmistakable even from across a room. Native to the Amazon Basin, this apex predator inhabits deep river channels and flooded forests where its flattened, spatulate head and keen sensory barbels allow it to hunt with devastating efficiency in low-visibility waters. At The Fish Collection, we source our Shovelnose Tiger Catfish from trusted South American exporters who prioritize specimen health and clean collection practices.

What sets the Shovelnose Tiger apart from other large predatory catfish is the combination of elegance and power. Unlike the bulkier Red Tail Catfish, the Shovelnose Tiger maintains a streamlined, torpedo-shaped profile throughout its life — a body plan built for speed and ambush predation. Adults reach approximately 51 inches in captivity, making this a true monster fish that demands serious infrastructure. A 300-gallon aquarium is the absolute minimum for a juvenile, and keepers should plan for a 500-gallon or larger system as the fish matures. Custom-built tanks or indoor ponds represent the ideal long-term housing solution.

Feeding a Shovelnose Tiger Catfish is a straightforward but critical aspect of husbandry. This is an obligate carnivore that feeds primarily on live and frozen fish in the wild. In captivity, we recommend a diet built around frozen silversides, smelt, prawns, and high-quality sinking pellets designed for large predatory catfish. Live feeder fish can be offered from quarantined sources but should not constitute the majority of the diet due to disease transmission risks. Feed juveniles every other day and taper to two to three times weekly for adults. These catfish are crepuscular feeders — most active at dawn and dusk — and many keepers find that feeding during low-light periods produces the most enthusiastic response.

Water parameters mirror standard Amazonian conditions: 72 to 82 degrees Fahrenheit, pH of 6.0 to 7.5, and soft to moderately hard water. The Shovelnose Tiger is reasonably adaptable but does best in well-oxygenated water with moderate to strong flow, replicating the riverine habitats it occupies in the wild. Filtration must be robust — sump systems rated for at least twice the tank volume, combined with regular 30 to 40 percent weekly water changes, are the baseline for maintaining water quality with a fish that produces a significant bioload.

Temperamentally, the Shovelnose Tiger Catfish is predatory and will consume any tankmate that fits in its remarkably wide mouth. Compatible companions are limited to fish of similar or larger size — Arowana, large Gar, and other hefty catfish species can coexist in sufficiently spacious systems. Many experienced keepers maintain Shovelnose Tigers as solitary specimens, which simplifies husbandry and allows the fish to claim the entire tank as its territory.

With a lifespan of 18 to 25 years, the Shovelnose Tiger Catfish is a long-term commitment that rewards dedicated keepers with one of the most dramatic and beautiful predatory fish in the freshwater hobby.
