Tiger Shovelnose Catfish

The Tiger Shovelnose Catfish, scientifically known as Pseudoplatystoma tigrinum, belongs to the Catfish family group. Adults reach a maximum size of approximately 120 cm and have a depressed body shape with a fast growth rate. Classified as semi-aggressive, this species primarily occupies the bottom zone of the aquarium and produces a extreme level of biological waste.

To thrive, the Tiger Shovelnose Catfish requires a freshwater only aquarium with a minimum volume of 3800 litres and a tank length of at least 300 cm. Water temperature should be maintained between 24°C and 28°C, with a pH range of 6–7.5 and a general hardness of 4–15 dGH. A moderate water flow is preferred.

Due to its specialist needs, the Tiger Shovelnose Catfish is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 2 varieties: Standard / Adult and Juvenile (Grow-out). Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.

When setting up an aquarium for the Tiger Shovelnose Catfish, a moderate water flow best suits their natural preferences. Because this species occupies the bottom zone, the aquarium layout should prioritise sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour, smooth gravel or rounded substrate to protect their sensitive barbels, and driftwood, which can serve as both a hiding place and a dietary supplement. Keepers should note that a tight-fitting lid is essential, as this species is a known jumper.

Classified as semi-aggressive, the Tiger Shovelnose Catfish is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, any fish small enough to fit in its mouth will likely be eaten and their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the bottom zone can help reduce competition and territorial overlap.

Tiger Shovelnose Catfish is best for a fishkeeper who wants a species that can settle into a calmer community setup and can provide someone who understands its individual space requirements. It makes the most sense for a hobbyist who will actually build around its needs, especially sand.

The most common mistake is treating Tiger Shovelnose Catfish like any other community fish and skipping the soft sand it needs to forage safely. Another frequent problem is forcing it into an over-busy community when it would do better with more room or more deliberate tankmate choices.

The Tiger Shovelnose Catfish is a predatory species that will readily consume small fish, so nano or bite-sized tankmates should be avoided and is primarily active at dusk and dawn, so offering food shortly after lights-off ensures it receives adequate nutrition.
