The upper lip is narrower than the lower lip, and the lower lip is divided into left and right sides. The distance between them is wider, about 1/3 of the mouth width. The posterior labial groove is short, interrupted at the forehead, and has a wide spacing. There are 2 pairs of barbels, both of which are slender. The kissing barbel is about 1/2 of the jaw barbel, and the jaw barbel is slightly larger than the eye diameter. The eyes are large.

The light-lipped fish likes to inhabit rivers with gravel bottoms and clear water and fast currents. It often uses its cuticles with well-developed jaws to shovel moss and algae on the rocks. They lay eggs in shallow rapids from June to August every year. Mainly distributed in streams in Shanghai, Jiangsu, Anhui, Zhejiang, Fujian, Taiwan and other places.

Widely distributed, it is a small economic fish in the production area and its meat is delicious. The eggs are toxic and if eaten by mistake, they can cause poisoning symptoms such as diarrhea, abdominal pain, dizziness, vomiting, etc. Cats, chickens and other animals that eat fish eggs can cause death. Prolonged heating can destroy toxins. Due to their bright body color, Zhejiang has selected 3.5 cm juvenile fish of the same type for export in recent years. As ornamental fish, 20,000 to 30,000 fish are exported every year, creating considerable value.
