L333 King Tiger Pleco - Hypancistrus sp L333

The King Tiger Pleco Catfish L333, scientifically known as Hypancistrus sp., is a captivating freshwater fish native to the Rio Xingu in Brazil. Its black body with bold white or yellow maze-like stripes creates a stunning display in planted or nano aquariums. Moreover, this peaceful bottom-dweller is a hardy addition, making it an ideal choice for aquarists seeking a visually striking, low-maintenance fish. Sourcing from captive-bred stocks is recommended due to threats from hydroelectric projects in its habitat.

Caring 

A tank of at least 115 litres suits the King Tiger Pleco Catfish L333, featuring a sand or fine gravel substrate, rocks, and driftwood caves to mimic its fast-flowing river environment. For instance, maintain water conditions with a pH of 5.5–7.5, a temperature of 26–30°C, and moderate to high water flow. Additionally, low to medium lighting and a secure lid are essential, as these nocturnal fish may move actively. Weekly 25–30% water changes and a strong filtration system manage their waste output.

Ideal Tank Mates

This species thrives in community tanks with peaceful fish like tetras, rasboras, or Corydoras catfish. However, avoid housing with other Hypancistrus species to prevent hybridisation, or aggressive fish like large cichlids. Males may be territorial with other males, so provide ample caves and hiding spots to reduce disputes. Furthermore, a tank with rockwork and driftwood supports their shy, nocturnal nature and encourages natural behaviour.

Feeding and Nutrition

As omnivores with a preference for protein, these fish thrive on a varied diet to maintain their vibrant patterns. For example, offer high-quality sinking pellets or algae wafers as a staple, supplemented with frozen or live foods like bloodworms, brine shrimp, or blackworms. Moreover, include occasional fresh vegetables like zucchini or cucumber for balance. Feed sparingly once daily, preferably at night, to align with their nocturnal habits and prevent water fouling.

Breeding King Tiger Pleco Catfish L333

Breeding this species is achievable in a 115-litre tank with multiple caves or slate niches for spawning. Maintain water at 26–30°C and a pH of 6.0–7.0 with high oxygenation to encourage spawning. Males guard eggs in caves, which hatch in 5–7 days. Consequently, fry should be fed infusoria or finely crushed foods, transitioning to baby brine shrimp as they grow. Remove adults post-hatching to protect fry.

Species Overview

The King Tiger Pleco Catfish L333 is a hardy, visually striking fish that enhances aquariums with its unique maze-like patterns and peaceful demeanour. Additionally, its manageable size (up to 13–15 cm) and minimal algae-eating habits make it suitable for intermediate aquarists. This species is not an effective algae eater but excels as a scavenger of uneaten food.
