The parrot fish sleeps in a mucus bag. This fish lives in the tropical coral reefs located in tropical oceans that are mainly around the equator. The parrot fish forms this mucus bag from a special gland in it body basically named the mucus gland. This bag that the parrot fish forms around its body is sticky and clear. I takes about a half hour to form and for the fish to break free in the morning. The mucus bag helps protect the fish during his sleep from predators and releases a sort of fragrance if you will to frighten predators away.
