In the phylum cnideria there are three classes. They are hydrozoa, scyphozoa, and anthozoa. In the class hydrozoa, their habitats are fresh and marine water. In scyphozoa, their habitats are marine only. In anthozoa, their habitats are marine only.
A genus of small, freshwater cnidarians (coelenterates) which belong to the class Hydrozoa. Hydra is an exceptional member of this class because it is a mobile individual polyp rather than a sessile or colonial form, and uses its cnidoblasts to capture prey. Unlike most Hydrozoa, which spend at least part of their lives in a medusa form, which reproduces sexually, Hydra exists only as polyps. They are typically a few millimeters long.

Because saltwater fish can only breathe in saltwater (as in the ocean) and freshwater fish can only breathe in freshwater (as in tap water.)
The question needs to be refined, as there are hundreds of freshwater fish species.
Only freshwater
The majority of the Earth's water is saltwater found in oceans. Only a small percentage, about 2.5%, is freshwater. However, much of this freshwater is frozen in ice caps and glaciers, or stored underground in aquifers, making only a small percentage of freshwater readily available for human use.
