The L201 Inspector Pleco is a small, peaceful species from the Rio Negro basin in Brazil, admired for its striking black body with white or yellowish spots. It thrives in soft, slightly acidic, well-oxygenated water with moderate flow and plenty of hiding spaces among rocks, driftwood, and caves. These nocturnal fish prefer dim lighting and clean, stable conditions, as they are sensitive to poor water quality. A temperature between 78–86°F (25–30°C) suits them best. They are omnivorous with a preference for protein-rich foods like sinking carnivore pellets, bloodworms, and brine shrimp, supplemented with occasional vegetable matter. Ideal for community tanks with peaceful tankmates, the L201 can live up to 10 years when properly cared for.
