The term "janitor fish" can be applied to any fish with an underslung suckermouth, including Plecos, Chinese Algae Eaters and Siamese Algae Eaters. And none of them perform any kind of "janitor" duty, Plecos in particular are HUGE waste producers, a happy Pleco is a pooping Pleco, and are actually quite the opposite of any kind of "janitor"!! Nothing eats fish poop.
WHen there is no other fish in the tank
Fish sleep on the ground.
