It belongs to nocturnal fish and can be mixed with healthy fish. It doesn't eat fish feed, but swims around the bottom and side of the fish tank. The places it swims in are particularly clean. Like a vacuum cleaner, the mouth of the sweeper sucked all the fish droppings and green plants into the stomach. It also has a bubble in its mouth, and this bubble contains oxygen, which can make it stay in the water for a long time and allow it to eat more "food". The scavenger takes fish excrement, seaweed, bacteria and feed residue as its main food, which has become the origin of its name.
