The Pleco is mainly an algae eater and that means good news for your aquarium. That annoying algae that grows everywhere is now a tasty meal for the Pleco. They are on a constant feeding frenzy of finding their next snack. There is realistically small algae particles everywhere in your tank, so the Pleco has it’s work cut out.
To make things even better, the Pleco is a true bottom feeder and will eat almost anything it can. They commonly get blamed for killing fish, but the truth is the fish died and sank to the bottom and the Pleco took action on its next food source. They will eat all those uneaten food particles that are bad news for nitrate levels too. They don’t eat poop but really help keep a tank clean.
