Tiger Shovelnose Zebra

Merodontotus tigrinus is a monotypic genus found in the upper Ucayali and other western Amazonian tributaries of Peru and Bolivia. Its bold, sharply defined vertical black-and-white banding is unique among pimelodids of comparable size and makes it instantly identifiable and visually spectacular. Very few specimens reach the export market in any given year.

In biology and care requirements it closely parallels other large shovelnose catfish. It is a powerful, active predator requiring an enormous tank with excellent filtration and pristine water quality. The species is particularly sensitive to elevated nitrates and ammonia spikes and requires strict water change discipline.

The Tiger Shovelnose Zebra is a significant investment and should only be attempted by keepers with substantial experience maintaining large predatory pimelodids. Its rarity and visual impact make it the crown jewel of any large South American catfish collection.
