Since most coldwater cnidaria are rare and coldwater corals only occur at great depths, hobbyists are largely confined to fish, crustaceans and mollusks. These tanks also tend to require extra skill to maintain.

Most colorful species are found in the western pacific and west coast of North America. However most coldwater fish are gray or dull in color. While most of these tanks are not as aesthetically pleasing as their tropical counterparts, colorful species such as dahlia anemones and the ornate cowfish can be found. One of the more obscure types of fish tanks, the coldwater marine tank, holds fish of temperate climates, with temperatures ranging around 10 to 24 degrees Celsius (50вЂ“75В вЏ).

By the 1980s, a biologically-based understanding of how to maintain an artificial ocean environment brought more successful and widespread marine fishkeeping. More efficient chemical testing allowed aquarists to understand the chemical properties of aquariums.

The advancement of fluorescent lighting technologies to provide higher output, along with metal halide lighting, enabled the first reef tanks, making it possible to keep corals and other invertebrates without natural sunlight. Various advances in filtration included trickle and hang-on filters, both allowing a more natural equilibrium in the aquarium environment. This advance made marine fishkeeping popular in areas without access to clean sea water.ДЄir driven, counter-current protein skimmers and reliable submersible electric heaters were invented in Germany. Synthetic salt mixes were developed to replicate the chemical environment of the tropical ocean, including trace elements and salts. Aquariums were equipped with large air compressors, and were heavily aerated and filtered (primarily with undergravel filters, a norm for some time).ДЄn ever-growing number of hobbyists experiencing the inconvenience of gathering natural sea water and the concurrent development of analytical chemistry techniques led to research into the chemical composition of sea water. Aquarium literature of the time suggests that the most commonly kept marine fish were the percula clownfish, sergeant major damselfish, small, brackish-water pufferfish and scats, jeweled blennies, and blue damsels. Natural saltwater contains many unwanted organisms and pollutants. Дuring the early days of marine aquaria, saltwater was collected at local beaches. The Aztec Empire had 10 ponds of saltwater aquariums at Texcoco. The clean, sterile tank was viewed as the healthiest. Algae, including beneficial types such as coralline algae, were viewed negatively and were generally removed. Bleached coral along with a substrate of coarse crushed coral were the norm. The first personal saltwater fishkeeping began on a wider scale in the 1950s, starting with the basic rectangular glass aquariums (usually 20 gallon), still popular today. The first saltwater tanks were Venetian glass jars where the Romans kept anemones outdoors, but these systems were very short lived. 2.2.2 Temperate marine (coldwater marine).However, the inhabitants of saltwater aquariums are usually much more spectacular than freshwater aquarium fish. The inhabitants of a marine aquarium are often difficult to acquire and are usually more expensive than freshwater aquarium inhabitants. A stable marine aquarium requires more equipment than freshwater systems, and generally requires more stringent water quality monitoring. Marine fishkeeping is different from its freshwater counterpart because of the fundamental differences in the constitution of saltwater and the resulting differences in the adaptation of its inhabitants. FOWLR and reef tanks use live rock, a material composed of coral skeletons harboring beneficial nitrogen waste metabolizing bacteria, as a means of more natural biological filtration. Fish only tanks often showcase large or aggressive marine fish species and generally rely on mechanical and chemical filtration. Marine aquaria are further subdivided by hobbyists into fish only ( FO), fish only with live rock ( FOWLR), and reef aquaria. A marine aquarium is an aquarium that keeps marine plants and animals in a contained environment.
