Map fish's black oval body is covered with irregular red and orange stripes, just like a map, hence its name. Because there is a black spot surrounded by gold at the end of its tail, which shines like a star, it is also called "Li Xing Fish". Some people call it "flower pig fish" because it is greedy and has the habit of being lazy at ordinary times.
Parrotfish, the scientific name is Luoshen neck fin fish, which is a genus of Pterodactylidae, commonly known as parrot fish, parrotfish, red wedge snapper and so on. Is a tropical fish that lives in coral reefs. At high tide, parrot fish, large and small, wearing bright green and yellow coats, swim from the deep water on the outer slope of coral reefs to shallow reefs and lagoons. Parrotfish has a special digestive system. Nautilus fish bite off corals along with bones with their plate-like beaks, then grind them with their throat teeth and swallow them into their stomachs. Nutrients are digested and absorbed, and coral fragments are eliminated from the body. The throat teeth of parrot fish are not as sharp as teeth, but have evolved into stone shapes. The maxillary surface of the throat teeth is convex, which matches the concave below.
