Gypsy King Tiger (L-66) Plecostomus

The Gypsy King Tiger Plecostomus (L-66) is one of the most striking and sought-after pleco varieties in the aquarium hobby. Known for its bold black-and-white striped pattern that resembles a tiger’s markings, this pleco is a favorite among aquarists who want a visually captivating and functional bottom-dweller. Native to the Rio Xingu in Brazil, the Gypsy King Tiger thrives in warm, fast-moving waters and brings that same vibrant energy to the home aquarium.

Reaching an adult size of around 5 to 6 inches, the Gypsy King Tiger Pleco is a medium-sized species that fits well in aquariums of at least 40 gallons. A tank with ample driftwood, smooth rocks, and hiding caves is essential, as this pleco enjoys retreating into shaded areas during the day and becoming more active at night. Unlike some other plecos, the L-66 does not grow excessively large, making it a great option for aquarists who want a manageable yet stunning pleco species.

This pleco thrives in water temperatures between 77–84°F (25–29°C), with a slightly acidic to neutral pH of 6.0–7.5. A sandy or fine gravel substrate is ideal, as it mimics its natural environment and allows the fish to comfortably forage along the bottom. Strong water flow, efficient filtration, and regular maintenance are important for keeping this species healthy, as it originates from fast-flowing river systems with clean, oxygen-rich water.

When it comes to diet, the Gypsy King Tiger Pleco is an omnivore with a preference for protein-rich foods. While it may graze on algae, it should not be relied on as the primary algae-eater of the aquarium. A balanced diet should include sinking carnivore pellets, high-quality pleco wafers, frozen or live foods such as bloodworms and brine shrimp, and the occasional vegetable treat like zucchini or cucumber. Providing a varied diet helps maintain its health, coloration, and activity levels.

In terms of temperament, the L-66 is generally peaceful but can become territorial with other plecos if space is limited. It does well in community tanks with similarly sized fish, such as cichlids, tetras, and rainbowfish, as long as it has its own hiding spots. Because of its nocturnal habits, it tends to stay out of the way of more active daytime fish, making it a compatible and low-maintenance addition to many setups.
