Flash Zebra Catfish (Leiarius sp. “Flash Zebra”)

The Flash Zebra Catfish is a rare and visually striking hybrid/variant prized for its bold, high-contrast striping and sleek, fast-swimming body. Combining the power and presence of large South American catfish with unique “zebra-like” patterning, this species stands out as a true showpiece in monster fish aquariums. Active, predatory, and fast-growing, the Flash Zebra is best kept by experienced hobbyists with large systems.

Sinking carnivore pellets (staple diet)
Frozen foods (shrimp, fish, krill)
Fresh cut fish or market shrimp
Occasional live foods (use sparingly)

They have a strong feeding response and should not be overfed.
