@animuspax: Pleco Genesis The Plecostomus, commonly known as a pleco, is one of the most popular tropical freshwater fish in the aquarium hobby. It belongs to the armored catfish family and is easily recognized by its sucker-shaped mouth and protective bony plates instead of regular scales. Plecos are often kept not only for their unique appearance but also because they help keep aquariums cleaner by grazing on algae growing on glass, rocks, and decorations. #fish #nature #pleco
