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. 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.
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". The aquarium principle was fully developed in 1850 by the chemist Robert Warington, who explained that plants added to water in a container would give off enough oxygen to support animals, so long as the numbers of animals did not grow too large.
World Association of Zoos and Aquariums
The World Association of Zoos and Aquariums (WAZA) is the "umbrella" organisation for the world zoo and aquarium community. Its mission is to provide leadership and support for zoos, aquariums, and partner organizations of the world in animal care and welfare, conservation of biodiversity, environmental education and global sustainability. The organisation is based in Gland, Switzerland. After an earlier International Union of Directors of Zoological Gardens (IUDZG), founded in 1935 at Basel, Switzerland, ceased to exist during World War II, a new IUDZG was founded in Rotterdam in 1946 by a group of zoo directors from allied or neutral countries.
Reef aquarium
A reef aquarium or reef tank is a marine aquarium that prominently displays live corals and other marine invertebrates as well as fish that play a role in maintaining the tropical coral reef environment. A reef aquarium requires appropriately intense lighting, turbulent water movement, and more stable water chemistry than fish-only marine aquaria, and careful consideration is given to which reef animals are appropriate and compatible with each other. Reef aquariums consist of a number of components, in addition to the livestock, including:  Display tank: The primary tank in which the livestock are kept and shown.
Freshwater aquarium
A freshwater aquarium is a receptacle that holds one or more freshwater aquatic organisms for decorative, pet-keeping, or research purposes. Modern aquariums are most often made from transparent glass or acrylic glass. Typical inhabitants include fish, plants, amphibians, and invertebrates, such as snails and crustaceans. Freshwater fish may be either coldwater or tropical species. Although freshwater aquariums can be set up as community tanks, coldwater and tropical fish are generally not mixed due to incompatibilities in temperature requirements. Coldwater aquariums house goldfish and other species that do not require a heating apparatus.
Canada's Accredited Zoos and Aquariums
Canada's Accredited Zoos and Aquariums - CAZA () is an accreditation and advocacy organization representing zoos and aquariums within Canada. The organization states that its member zoos and aquariums care for more than 100,000 individual animals representing over 2000 species of wildlife, observed by an estimated 11 million visitors each year. The organization is a member of the International Union for Conservation of Nature and the World Association of Zoos and Aquariums. The organization was founded in 1975 at a conference of the Association of Zoos and Aquariums (then named the American Association of Zoological Parks and Aquariums).
List of marine aquarium fish species
The following list of marine aquarium fish species commonly available in the aquarium trade is not a completely comprehensive list; certain rare specimens may available commercially yet not be listed here. A brief section on each, with a link to the page about the particular species is provided along with references for further information. These large fish are considered to be quite hardy, but because of their size may present a significant challenge to the keeper. They need huge aquariums, up to 180 gallons to house one for its entire lifespan. Two angels might be kept in the same aquarium provided it is a large aquarium, they are properly acclimated as juveniles, and they have very different colouring and body shape.

Fishkeeping
Fishkeeping is a popular hobby, practiced by aquarists, concerned with keeping fish in a home aquarium or garden pond. There is also a piscicultural fishkeeping industry, as a branch of agriculture. Fish have been raised as food in pools and ponds for thousands of years. Brightly colored or tame specimens of fish in these pools have sometimes been valued as pets rather than food. Many other cultures kept fish for both functional and decorative purposes. Ancient Sumerians kept wild-caught fish in ponds, before preparing them for meals. Depictions of the sacred fish of Oxyrhynchus kept in captivity in rectangular temple pools have been found in ancient Egyptian art.
Aquatic mammal
Aquatic and semiaquatic mammals are a diverse group of mammals that dwell partly or entirely in bodies of water. They include the various marine mammals who dwell in oceans, as well as various freshwater species, such as the European otter. They are not a taxon and are not unified by any distinct biological grouping, but rather their dependence on and integral relation to aquatic ecosystems. The level of dependence on aquatic life are vastly different among species, with the Amazonian manatee and river dolphins being completely aquatic and fully dependent on aquatic ecosystems; whereas the Baikal seal feeds underwater but rests, molts, and breeds on land; and the capybara and hippopotamus are able to venture in and out of water in search of food.
Green sea turtle
The green sea turtle ("Chelonia mydas"), also known as the green turtle, black (sea) turtle or Pacific green turtle, is a large sea turtle of the family Cheloniidae. It is the only species in the genus Chelonia. Its range extends throughout tropical and subtropical seas around the world, with two distinct populations in the Atlantic and Pacific Oceans, but it is also found in the Indian Ocean. The common name comes from the usually green fat found beneath its carapace; these turtles' shells are olive to black. This sea turtle's dorsoventrally flattened body is covered by a large, teardrop-shaped carapace; it has a pair of large, paddle-like flippers.
Lake ecosystem
A lake ecosystem includes biotic (living) plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions. Lake ecosystems are a prime example of lentic ecosystems. "Lentic" refers to stationary or relatively still water, from the Latin "lentus", which means sluggish. Lentic waters range from ponds to lakes to wetlands, and much of this article applies to lentic ecosystems in general. Lentic ecosystems can be compared with lotic ecosystems, which involve flowing terrestrial waters such as rivers and streams. Together, these two fields form the more general study area of freshwater or aquatic ecology.
Turtle
Turtles are reptiles of the order Testudines (or Chelonii) characterized by a special bony or cartilaginous shell developed from their ribs and acting as a shield. "Turtle" may refer to the order as a whole (American English) or to fresh-water and sea-dwelling testudines (British English). The order Testudines includes both extant (living) and extinct species. The earliest known members of this group date from , making turtles one of the oldest reptile groups and a more ancient group than snakes or crocodilians. Of the 356 known species alive today, some are highly endangered. Turtles are ectotherms—animals commonly called cold-blooded—meaning that their internal temperature varies according to the ambient environment.
Aquaculture
Aquaculture is the farming of fish, crustaceans, molluscs, aquatic plants, algae, and other aquatic organisms. Aquaculture involves cultivating freshwater and saltwater populations under controlled conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish. It is less commonly spelled aquiculture), and is also known as aquafarming. Mariculture refers to aquaculture practiced in marine environments and in underwater habitats. According to the Food and Agriculture Organization (FAO), aquaculture "is understood to mean the farming of aquatic organisms including fish, molluscs, crustaceans and aquatic plants.

That is so cool.  Is it hard to build auariums?

Correct! I always admire Robert Warington because he developed the complex idea of an aquarium in 1850!
The aquarium principle was fully developed in 1850 by the chemist Robert Warington, who explained that plants added to water in a container would give off enough oxygen to support animals, so long as the numbers of animals did not grow too large.

Robert Warington
Robert Warington FRS (7 September 1807 – 17 November 1867) was an English chemist considered the driving force behind the creation of the world's first enduring chemistry society, The Chemical Society of London, which later became the Royal Society of Chemistry. Born on 7 September 1807 in Sheerness, Kent, he was the third son of Thomas Warington (1773-1843), a ship's victualler and wine merchant, and his wife Esther Elizabeth Eaton (1779-1861). One of his uncles was Thomas Warington (1765-1850), the father-in-law of Admiral William Henry Smyth. After a childhood spent in Portsmouth, Boulogne, and other places, he entered Merchant Taylors' school in 1818 and in 1822 was articled for five years to John Thomas Cooper, a lecturer in the medical schools of Aldersgate Street and Webb Street, and a manufacturer of potassium, sodium, iodine, and other then-rare chemical substances.
Katherine Warington
Katherine Warington (5 September 1897 – 3 July 1993) was a botanist and the first person to show that boron, as boric acid, was essential for the healthy growth of plants. Katherine Warington was born in Harpenden, Hertfordshire on 5 September 1897, a twin and one of the five daughters of Helen Louisa Makins and the agricultural chemist Robert Warington FRS [Jnr]. She was educated at the all-women Holloway College, University of London graduating with a B.Sc (Hons) in Botany in 1921. In 1923 she gained her MSc from the University of London with her thesis: The effect of boric acid and borax on the broad bean and certain other plants.
Warington Baden-Powell
Henry Warington Smyth Baden-Powell KC (3 February 1847 – 4 April 1921), known as Warington within the family, was a British merchant marine, canoeist, and naval law expert. The oldest brother of Scouting pioneer Robert Baden-Powell, Warrington Powell was instrumental in the founding of Sea Scouting. Warrington Powell was the brother of Robert Baden-Powell, Agnes Baden-Powell, George Baden-Powell, Frank Baden-Powell, and Baden Baden-Powell, the son of Baden Powell. His mother, Henrietta Grace Smyth, was the third wife of Rev. Baden Powell (the previous two having died), and was a gifted musician and artist.
Soil
Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. The Earth's body of soil is the pedosphere, which has four important functions: it is a medium for plant growth; it is a means of water storage, supply and purification; it is a modifier of Earth's atmosphere; it is a habitat for organisms; all of which, in turn, modify the soil. Soil interfaces with the lithosphere, the hydrosphere, the atmosphere, and the biosphere. The term "pedolith", used commonly to refer to the soil, literally translates "ground stone". Soil consists of a solid phase of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution).
A Treatise of Human Nature
A Treatise of Human Nature (1738–40) is a book by Scottish philosopher David Hume, considered by many to be Hume's most important work and one of the most influential works in the history of philosophy. The "Treatise" is a classic statement of philosophical empiricism, skepticism, and naturalism. In the introduction Hume presents the idea of placing all science and philosophy on a novel foundation: namely, an empirical investigation into human nature. Impressed by Isaac Newton's achievements in the physical sciences, Hume sought to introduce the same experimental method of reasoning into the study of human psychology, with the aim of discovering the "extent and force of human understanding".
Gua-Le-Ni; or, The Horrendous Parade
Gua-Le-Ni; or, The Horrendous Parade is an action puzzle video game designed by Stefano Gualeni. Developed between 2011 and 2012 by Double Jungle S.a.S. and Stefano Gualeni, "Gua-Le-Ni" is the first commercially released casual video game that was designed and tuned with the support of biometric experiments. "Gua-Le-Ni" takes place on the wooden desk of an old, befuddled British taxonomist. On his desk, lies a fantastic book: a bestiary populated by finely drawn creatures. As for the monsters of myths and folklores in general, the impossible creatures in "Gua-Le-Ni" are combinations of parts of real animals.
