The keeping of saltwater fish species is infrequently recorded in ancient history. It wasn’t until the nineteenth century that a real push began to explore the inhabitants of the sea. In the early 1800’s successful keeping of marine invertebrates is cited, but keeping marine fish developed a bit later. The first successful collection of saltwater fish, and then successfully keeping saltwater aquariums is credited to William E. Damon in the 1870’s.

Still it wasn’t until almost a century later, about the 1950’s, that interest in the hobby really began to take root, and by the 1980’s, major strides were made in aquarium husbandry. At this time how to biologically maintain an artificial ocean environment was developed, what today is commonly known as the nitrification cycle. With this development, saltwater fishkeeping became very successful and is an exciting widespread hobby today.

Animal-World fish guides provide information on many types of saltwater aquarium fish and others. The list of fish includes all types of marine fish from well-known popular species like Damsels, Angelfish, and Tangs, to the more exotic marine species like Sharks, Rays and others. The list of saltwater fish is constantly expanding to include even more exotic fish types like Anglers and Toadfish, Grunts, Jawfish, Seahorses and Pipefish, Tilefish, Snappers, Scorpions, Rockfish, and more.

Fish pictures of each type of marine fish are provided within each fish guide. These not only help with saltwater fish identification, but aid in choosing pet fish. The fish guides also have in-depth fish information, covering everything from their native place of origin and when first scientifically described, to the habitats and behaviors of each species. Each guide then provides the fish care needed to successfully keep them in a saltwater aquarium.
