The Common Pleco (Hypostomus plecostomus), also known as the Common Suckermouth Catfish, is a popular freshwater fish in the aquarium hobby. It is native to South America, where it is found in rivers and streams with a slow to moderate current.


Common Plecos are known for their distinctive appearance, with a long, flat body and a large head. They have a mouth that is adapted for scraping algae off surfaces, and they are often used in aquariums to help control algae growth. They can grow quite large, reaching up to 18-24 inches in length, so they require a large tank with plenty of swimming room.


In terms of care, Common Plecos require a well-established aquarium with plenty of hiding places and driftwood to graze on. They are omnivores and will eat algae, as well as commercial sinking pellets, vegetables, and frozen or live foods. It is important to avoid overfeeding, as this can lead to health issues and poor water quality.


Common Plecos are generally peaceful, but they can become territorial and aggressive towards other bottom-dwelling fish as they mature. They are also known to be active at night, so it is best to provide them with a dark place to hide during the day.
