Hypostomus plecostomus, also known as the suckermouth catfish or common pleco, is a tropical freshwater fish belonging to the armored catfish family (Loricariidae), named for the longitudinal rows of armor-like scutes that cover the upper parts of the head and body (the lower surface of head and abdomen is naked soft skin).
Members of the family Loricariidae are commonly referred to as loricariids, suckermouth catfishes, armoured catfish, or suckermouth armoured catfish. [4] The name "plecostomus", and its shortened forms "pleco" and "plec", are used for many Loricariidae, since Plecostomus plecostomus (now called Hypostomus plecostomus) was one of the first loricariid species imported for the fish-keeping hobby.
The swim bladder, gas bladder, fish maw, or air bladder is an internal gas-filled organ in bony fish (but not cartilaginous fish [1]) that functions to modulate buoyancy, and thus allowing the fish to stay at desired water depth without having to maintain lift via swimming, which expends more energy.

Historically, the flannelmouth sucker ranged in the Colorado River Basin, including parts of Wyoming, Utah, Colorado, New Mexico, Nevada, California, and Arizona; however, this species has been entirely extirpated from the ...
Suckerfish or sucker may refer to: the remoras (family Echeneidae): ray-finned fishes that use suction to hold onto larger marine animals; the family Catostomidae (suckers): freshwater fish found mostly in North America; the species Hypostomus plecostomus (the suckermouth catfish), or other members of family Loricariidae
Throughout much of their range species are considered to be rough fish. Suckers have historically been scapegoated for human environmental destruction and their impacts on popular fish species such as Pacific salmon and smallmouth bass. This has led to their widespread and unnecessary destruction at the hands of ignorant anglers. [12]
The creek chubsucker is an important species in lotic water systems. It is a fish that turns over energy by consuming vegetation detritus. [17] The creek chubsucker also regulates population levels of macro-invertebrates and algae, and it serves as an important prey fish for many desirable game fish species. [7]
The sucker feeds on algae, detritus, and small invertebrates from bottom substate using their vacuum-like lips to suck in food; feeding is most active at night. [ 4 ] The Sacramento sucker are strong swimmers overall using strategic sources for water flow and can be found in zones of channel margin or debris. [ 4 ]
