Other names: Common pleco
The common pleco, Hypostomus plecostomus, is a freshwater catfish native to South America, popular in the aquarium trade for its algae-eating habits. It has a distinct armored body and a suckermouth used to attach to surfaces. Plecos are nocturnal and prefer hiding during the day. Though initially small, they can grow significantly, which makes them less suitable for small home aquariums.
