freshwater snapper and freshwater snapper are not the same kind of fish. Freshwater Diao fish refers to a kind of Cyprinidae fish, whose scientific name is Hemiculter leucisculus, also known as white-nosed fish. The freshwater snapper refers to a kind of snakehead fish, whose scientific name is Cirrhinus molitorella, also known as snakehead.

There are obvious differences between the two kinds of fish in morphology, ecological habits and distribution areas. Freshwater diaoyu is usually short, spindle-shaped, with a dark blue-gray back and a shallow abdomen. It mainly inhabits rivers and lakes, likes to move on the water surface and feeds on plankton and benthic small invertebrates. However, freshwater snapper has a large body length, a flat side, a brown back and a gray abdomen. It mainly inhabits the middle and lower waters of rivers and lakes and feeds on zooplankton, benthos and plants.

Generally speaking, there are great differences in appearance, habits and eating habits between freshwater fish and freshwater fish. Therefore, they belong to different fish. In terms of expansion, we can further introduce the characteristics and classification of CYPRINIDAE and CYPRINIDAE, as well as their functions and importance in the ecological environment.
