When nutritious and delicious fish worms and fish food are placed in front of them, they will never take a fancy to the residual bait and dirt. Scavengers are not very good ornamental fish species. They rest during the day and move at night. They will bite aquatic plants like fishing nets.
In addition, if the fish is sick, it will stick to the body and bite the wound at night. Garbage collectors have a lot of shit, which is not clean, but will make the situation worse.

"theoretically, you can eat it, but it is not recommended." Yu Xuerong, executive president of Jiangsu Catering Industry Association, said that scavenger fish is an ornamental fish and not suitable for eating. "Fish is rich in protein and many people like to eat it. Nowadays, edible fish are basically scientifically farmed, while ornamental fish are not scientifically farmed fish species, and their nutrition is unbalanced, which cannot provide the protein needed by the human body.
