Pleco is the common name for Catfish species in the Family Loricariidae. The name Pleco is derived from the Latin name of one of the species in this family, the Hypostomus plecostomus, and is today widely used even for the other species in this family. The Family Loricariidae is also known as the Armored Catfish family, since the fish in this family display longitudinal rows of scutes over the upper parts of the head and body, and this pattern is somewhat similar to an old armor.
Plecos are very popular aquarium fish, even for beginners. They can help keeping unwanted algae growth under control in the aquarium, since algae and plant material are their staple foods in the wild.
