saltwaterfish aquarium 10
saltwater fish, also called marine fish, are fish that live in ocean water. Saltwater fish can swim and live alone or in a large group called a school.
Saltwater fish are very commonly kept in aquariums for entertainment. Many saltwater fish are also caught to be eaten, 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.
