Saltwater Fish are wildly popular today, as science and technology have made it easier than ever to own and operate a saltwater fish tank. Many species of Saltwater Fish are aquacultured and others are humanely collected from all of the tropical oceans of the world. Saltwater Fish are desirable for their bright colors, bold patterns, and ease of care. There are reef safe fish and predatory fish, so hobbyists must consider tank size and compatibility so their Saltwater Fish will live a long healthy life.
