Yellow-lipped fish is one of the "Ten Treasures of the Ocean" selected by WWF, which is the most endangered but the least concerned. China also has yellow-lipped fish aquaculture. The jelly made from the swim bladder of yellow-lipped fish is very precious and is often regarded as a family heirloom by the family.

Myxocyprinus of Catostomidae, Cyprinidae.
The picture below shows Myxocyprinus asiaticus, also known as yellow steak, blood steak, vermicelli steak, burnt bream, wood leaf plate, red fish, wood leaf fish, purple bream, finch fish, fire steak and Chinese sail fin sucking fish.
The juvenile Myxocyprinus asiaticus is brown and has three dark bands. The obvious difference between adult male fish and female fish is that the male fish is rouge red, while the female fish is deep purple with broad vertical stripes. Another important feature of Myxocyprinus asiaticus is its towering triangular dorsal fin, which extends all the way to the back of the anal fin. Its fleshy lips are thick and there are papillae on it, so it is unnecessary. Myxocyprinus asiaticus has a single row of pharyngeal teeth, which are arranged in a comb shape. With the increase of age, the body color of adult mullet will become darker and darker; In his later years, the characteristics of white stripes on his body will disappear.
Cyprinidae? Cyprinidae ? Tanichthys fish of the genus Tangyu.
The following picture shows the Tang fish Tanichthys albonubes, commonly known as Baiyun Mountain Fish, Baiyun Golden Fish, Red-winged Fish, Red-tailed Fish, Golden Lantern, Guangdong Fine Crucian Carp and Pan Shi Fine Crucian Carp?
The female fish is stout and dull in color. It is very easy for Tang fish to breed, which is very suitable for lovers who are exposed to tropical spawning fish for the first time to experiment. The small breeding tank with suitable water temperature of about 22 ~ 25℃, water hardness of 6 ~ 8 and pH value of about pH7.0 is paved with a layer of Fontinalis Antipyretica or brown silk sterilized by hot water at high temperature as the hatching nest of fish eggs. Then, select fully mature and healthy parents, and put them into the breeding tank according to the male-female ratio of 1: 1 or 1:2. In a quiet environment, the male and female fish will soon enter the "estrus" state, and the male fish will keep chasing the female fish until the female fish lays her eggs in the water grass, and the male fish will immediately fertilize them. Fish eggs are white, transparent and sticky, and they stick to aquatic plants, and the number is between 200 and 300. Fish can be fished out after spawning, so as to prevent them from swallowing fish eggs.

Carnivorous fish inhabiting the bottom of sand and mud, their young fish grow in rivers, and adult fish fall into the sea in late spring and early summer to lay eggs. After hatching, the young fish change into a transparent eel line through the willow-leaf stage, and it takes five months to return to the river to survive. During the day, the whole body is hidden in the mud, only one head is exposed to breathe, and at night, it swims out to feed on other fish, shrimp and crabs.
