Saltwater fish, also called marine fish, are fish that live in ocean water. Saltwater fish can swim and live alone or live in a large group together, called a school of fish. Saltwater fish are very popular among deep sea fishermen and aquariums all over the country. Saltwater fish are very commonly kept in aquariums for entertainment. Many saltwater fish are also caught to be eaten.

Diet
Fish that live in the ocean can be carnivores, herbivores, or omnivores. Herbivores in the ocean eat things such as algae and flowering seagrasses. Many herbivores' diets consist of primarily algae. Most saltwater fish will eat both macroalgae and microalgae. Many fish eat red, green, brown, and blue algae, but some fish prefer certain types. Most saltwater fish that are carnivores will never eat algae under any circumstances. Carnivores' diets consist of shrimp, plankton, or tiny crustaceans.

Captivity
Saltwater aquariums are a multi-million dollar industry in the United States. About 10 million marine fish are imported into the United States each year for aquarium use. The United States imports more saltwater fish than any other country in the world. There are approximately 2,000 different species of saltwater fish that are imported and used in captivity. In many circumstances, fish used for marine trade are collected using harmful tactics such as cynide. One way that people are trying to protect the coral reefs is by breeding marine fish in captivity. Captive-bred fish are known to be healthier and likely to live longer. Captive-bred fish are less susceptible to disease because they have not been exposed to the wild and they have not been damaged during the shipment process. Fish that are bred in captivity are already accustomed to aquarium habitats and food.

Habitats
There are many different components that make up a marine life habitat. Some components are the temperature of the water, the quality, and quantity of water (flow and depth). There are other physical features that contribute to a habitat which are physical materials like rocks, reefs, and sand or the vegetation like the amount of algae, water plants, and saltmarsh. Specific fish live in specific habitats based on what they eat or what cycle of life they are currently at, another thing is the amount of salt that is in the water at that specific location. Another thing is that some ocean habitats aren't technically in the ocean and these are called estuaries which are areas when oceans and rivers meet creating a mixture of salt water and freshwater making a different habitat for different types of fish and creatures to live in. The ocean is home to organisms as large as whales and as small as microscopic marine organisms such as phytoplankton. However, the vast majority of ocean life that humans are exposed to is simple saltwater fish. Saltwater fish can live in the deepest depths of the ocean where no sunlight can penetrate, but they can also live on the surface of the water.

The magnets used for this hobby are strong enough to pull heavy items out of the water. Some people use magnet fishing as a way to find large, submerged items, but others are looking for valubles and rare treasures (Johnson).
