The Blue Phantom Plecostomus originates from the rapids of the Rio Orinoco in Venezuela and even further downstream. The Pleco’s broad flat head and body shape helps it navigate (or stay put) in very strong currents with minimal effort. With its overall muted blue coloration and lighter colored polka dots, this visually alluring algae eater makes a great choice for freshwater hobbyists in search of unusual aquarium inhabitants.

The Blue Phantom Plecostomus requires an established aquarium to thrive. It is critical to maintain high water quality and aeration plus strong water movement to ensure the health of the Blue Plecostomus. A fast-moving, oxygen-rich environment can be achieved through the use of powerheads. They will also do well in aquariums with less hectic water movement.


Blue Phantom Plecos are omnivores and will fare well in a mature aquarium with driftwood and smooth edged or rounded rocks that host algae and biofilm . Supplement the diet of their diets with foods that sink to the bottom of the aquarium such as a high-quality flake food and sinking algae or spirulina pellets and wafers.
