Hypostomus plecostomus, commonly known as the suckermouth catfish or the common pleco, is a tropical freshwater fish that belongs to the armored catfish family (Loricariidae). It is recognized for its distinctive feature of longitudinal rows of armor-like scutes that cover the upper parts of its head and body, while the lower surface of the head and abdomen is covered in soft, naked skin.
Although the name Hypostomus plecostomus is frequently used to refer to the common plecostomus available in aquarium shops, most of the specimens sold actually belong to other genera. It is important to note this distinction.
Suckermouth catfish, including Hypostomus plecostomus, have limited or no commercial value as food fish. However, there is a demand for them in the aquarium trade due to their role as bottom cleaners. They are valued for their ability to help maintain the cleanliness of aquariums.
Please note that the specific information regarding the consumption of suckermouth catfish in their native range is not well-documented or confirmed.
