  • Originating from South America, Pleco L001 is well known for its adaptability, resilience, and algae-grazing behavior.

  • This pleco is best suited for aquarists who appreciate large, long-term fish and have the tank space to accommodate its adult size.

• Appearance & Physical Characteristics
