Where did the Plecostomus come from?

The Plecostomus, commonly known as "plecos," originated from the freshwater rivers and streams of South America, particularly in countries like Brazil, Paraguay, and Argentina. They are part of the family Loricariidae and are known for their unique armored bodies and algae-eating habits. These fish thrive in various aquatic environments, including slow-moving waters and areas with abundant vegetation.
