A marine aquarium is an aquarium that keeps marine plants and animals in a contained environment. Marine aquaria are further subdivided by hobbyists into fish only (FO), fish only with live rock (FOWLR), and reef aquaria. Fish only tanks often showcase large or aggressive marine fish species and generally rely on mechanical and chemical filtration. 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.
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. A stable marine aquarium requires more equipment than freshwater systems, and generally requires more stringent water quality monitoring. The inhabitants of a marine aquarium are often difficult to acquire and are usually more expensive than freshwater aquarium inhabitants. However, the inhabitants of saltwater aquariums are usually much more spectacular than freshwater aquarium fish.

Famous quotes containing the words marine and/or aquarium:
“People run away from the name subsidy. It is a subsidy. I am not afraid to call it so. It is paid for the purpose of giving a merchant marine to the whole country so that the trade of the whole country will be benefitted thereby, and the men running the ships will of course make a reasonable profit.... Unless we have a merchant marine, our navy if called upon for offensive or defensive work is going to be most defective.”
—William Howard Taft (1857–1930)
“one is in a shoe factory cursing the machine,
one is at the aquarium tending a seal,
one is dull at the wheel of her Ford,
one is at the toll gate collecting,
one is tying the cord of a calf in Arizona,
one is straddling a cello in Russia....”
—Anne Sexton (1928–1974)
