Saltwater fish

Saltwater fish, also called marine fish or sea fish, are fish that live in seawater. Saltwater fish can swim and live alone or in a large group called a school.^[1]

Saltwater fish are very commonly kept in aquariums for entertainment. Many saltwater fish are also caught to be eaten,^[2]^[3] or grown in aquaculture. However, many fish species have been overfished and are otherwise threatened by marine pollution or ecological changes caused by climate change.
