At night, these fish find crevices to hide away in, then they secrete mucus from special organs around their gills that forms into a cocoon-like sleeping bag. These sleeping bags stop the smell of their bodies from leaking out, making them harder for predators to detect. It's also thought that they help to protect the fish from parasites.
