L333 White King Tiger Pleco

White King Tiger Pleco (Hypancistrus sp. L333)

A highly popular and intricately patterned pleco from the Xingu River in the Lower Amazon basin of Brazil. Known in the hobby by its L-number (L333) and nicknamed the “Maze Zebra Pleco” for its striking labyrinthine black-and-white or black-and-yellow patterning, this species stands out with its bold geometric design and relatively large size for the genus. It is one of the most sought-after Hypancistrus in the aquarium trade and remains a favorite among enthusiasts who appreciate its unique appearance and interesting behaviors.

Key Features

• Maximum Size: 15 cm / ~5.9 inches SL.
• Appearance: Compact, armored body with a dramatic maze-like zebra pattern of bold black lines on a lighter background. Males develop thicker pectoral fin rays and more pronounced odontodes (bristles) on the cheeks and body; females are broader around the midsection with less prominent bristles.
• Fin Details: Typical for the genus, with strong pectoral spines and rounded fins suited to their bottom-dwelling lifestyle.

Aquarium Care

• Tank Size: Minimum 40–55 gallons for a small group or community setup (larger is better).
• Water Parameters: Tropical freshwater; 79–88°F (26–31°C), pH 6.4–7.2, very soft to soft (80–120 µS/cm). Excellent water quality, good oxygenation, and moderate to fast current are important. Provide plenty of driftwood, caves, and hiding spots (slate, bamboo, or PVC pipes work well for breeding).
• Diet: Carnivorous — readily accepts meaty foods such as bloodworm, brine shrimp, and high-quality sinking carnivore pellets or discus food. Unlike many plecos, it is not a strong algae grazer and performs best with a protein-rich diet.
• Behavior: Generally peaceful but can be territorial with other plecos, especially in smaller tanks. Shy at first but becomes more active once settled. Closed cave spawner; the male guards the eggs and fry. Excellent for larger planted or biotope aquariums with other peaceful fish that won’t compete aggressively for food.
