I blog about salt water aquarium as everyone seems to love a  marine aquarium that  keeps marine plants and animals in a contained environment.
Interesting. What are the best fish to keep in a salt water aquarium?
I will just talk in general about an aquarium. You can find fish, invertebrates, amphibians, aquatic reptiles such as turtles, and aquatic plants in an aquarium
Cool. What type of people seem to most enjoy aquariums?
Marine aquarium
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.

Aquarium
An aquarium (plural: "aquariums" or "aquaria") is a vivarium of any size having at least one transparent side in which aquatic plants or animals are kept and displayed. Fishkeepers use aquaria to keep fish, invertebrates, amphibians, aquatic reptiles such as turtles, and aquatic plants. The term "aquarium", coined by English naturalist Philip Henry Gosse, combines the Latin root "aqua", meaning water, with the suffix "-arium", meaning "a place for relating to".
