The Sailfin Pleco (Pterygoplichthys gibbiceps) is a popular freshwater catfish known for its impressive, sail-like dorsal fin and its role as a “tank cleaner” that eats algae. Native to the Amazon and Orinoco basins in South America, these hardy fish are often sold small but can grow into “monsters” reaching 18 to 24 inches (45–60 cm) in length.
