Freshwater fish:
Freshwater fish are the most common freshwater organisms. Broadly speaking, the fish that can live in fresh water with a salinity of three thousandths of a degree can be called freshwater fish. In a narrower sense, it refers to a fish that spends part of its life history as a "juvenile" or "adult" or that must spend its entire life in freshwater.
The Earth's freshwater area is small, but freshwater fish are exceptionally rich, accounting for 41.2% of the total fish population. There are about 28,000 species of fish globally (more than 26,000 species have been recorded), and about 10,700 species of freshwater fish. Although the total number of fish is less than saltwater fish, but freshwater waters account for only 2.5% of the total waters, so freshwater fish is much richer than saltwater fish.
