Pearl fish, scientific name Neoglyphidodonnigroris, is a small warm-water fish that lives in coral reef areas. Their bodies are brightly colored, usually with white or light gray background and blue or black spots, which are very beautiful. Pearl fish usually like to live in rocky seabed, coral reefs and the bottom of tidal rocks. They are omnivorous and feed on plankton, meiobenthos and algae.

Their bodies are usually oval, their heads are short, their mouths are small and round, their positions are low, and there are 12- 14 black horizontal bands on their sides.

Pearl fish is not only welcomed by local fishermen and seawater lovers because of its unique body shape and bright colors, but also becomes one of the most popular ornamental fish species in international aquariums.
4. The protection status of pearl fish.
Due to global environmental degradation and overfishing, the number of pearl fish is decreasing. In order to protect this species, it is necessary to maintain ecological balance by strengthening coral reef protection and limiting fishing. At the same time, in order to let more people know and pay attention to the protection of pearl fish, it is also necessary to strengthen publicity and education and raise public awareness of environmental protection. Only by working together can we protect these precious marine living resources.
