Macropodus Ocellatus
The round-tailed paradise fish (''Macropodus ocellatus'') is a species of gourami native to eastern Asia, where it is found in Korea and China. It is also found in Japan but it is believed that they were introduced from Korea in the 1910s. It is also known to occur in the Amur Basin of Russia, but that is believed to be due to introductions. It inhabits many kinds of freshwater habitats within its range. This species is reported to be well adapted to cold weather during winter in its relatively northern range, even to the point of remaining active when their body of water is covered with ice. This species grows to a standard length of , and can be found in the 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.

Theodore Edward Cantor
Theodore Edward (Theodor Edvard) Cantor (1809–1860) was a Danish physician, zoologist and botanist. Born to a Danish Jewish family, his mother was a sister of Nathaniel Wallich. Cantor worked for the British East India Company, and made natural history collections in Penang and Malacca. Cantor was the first Western scientist to describe the Siamese fighting fish. In the scientific field of herpetology he described many new species of reptiles and amphibians. Species first described by Cantor include '' Bungarus bungaroides'' (1839), ''Bungarus lividus'' (1839), ''Channa argus'' (1842), '' Elaphe rufodorsata'' (1842), ''Euprepiophis mandarinus'' (1842), '' Hippocampus comes'' (1850), '' Lycodon effraenis'' (1847), ''Misgurnus anguillicaudatus'' (1842), ''Naja atra'' (1842), '' Oligodon albocinctus'' (1839), '' Oligodon cyclurus'' (1839), '' Ophiophagus hannah'' (1836), '' Oreocryptophis porphyracea'' (1839), ''Pareas monticola'' (1839), ''Protobothrops mucrosquamatus'' (18 ...

John Richardson (naturalist)
Sir John Richardson Royal Society of London, FRS FRSE (5 November 1787 – 5 June 1865) was a Scotland, Scottish naval surgeon, natural history, naturalist and Arctic explorer. Life Richardson was born at Nith Place in Dumfries the son of Gabriel Richardson, Provost of Dumfries, and his wife, Anne Mundell. He was educated at Dumfries Grammar School. He was then apprenticed to his maternal uncle, Dr James Mundell, a surgeon in Dumfries. He studied medicine at Edinburgh University, and became a surgeon in the navy in 1807. He traveled with John Franklin in search of the Northwest Passage on the Coppermine Expedition of 1819–1822. Richardson wrote the sections on geology, botany and ichthyology for the official account of the expedition. Franklin and Richardson returned to Canada in 1825 and went overland by fur trade routes to the mouth of the Mackenzie River. Franklin was to go as far west as possible and Richardson was to go east to the mouth of the Coppermine River. These ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gourami
Gouramis, or gouramies , are a group of freshwater anabantiform fishes that comprise the family Osphronemidae. The fish are native to Asia—from the Indian Subcontinent to Southeast Asia and northeasterly towards Korea. The name "gourami", of Indonesian origin, is also used for fish of the families Helostomatidae and Anabantidae. Many gouramis have an elongated, feeler-like ray at the front of each of their pelvic fins. All living species show parental care until fry are free swimming: some are mouthbrooders, like the Krabi mouth-brooding betta (''Betta Simplex''), and others, like the Siamese fighting fish (''Betta splendens''), build bubble nests. Currently, about 133 species are recognised, placed in four subfamilies and about 15 genera. The name Polyacanthidae has also been used for this family. Some fish now classified as gouramis were previously placed in family Anabantidae. The subfamily Belontiinae was recently demoted from the family Belontiidae. As labyrinth fishe ...

Korea
Korea ( ko, 한국, or , ) is a peninsular region in East Asia. Since 1945, it has been divided at or near the 38th parallel, with North Korea (Democratic People's Republic of Korea) comprising its northern half and South Korea (Republic of Korea) comprising its southern half. Korea consists of the Korean Peninsula, Jeju Island, and several minor islands near the peninsula. The peninsula is bordered by China to the northwest and Russia to the northeast. It is separated from Japan to the east by the Korea Strait and the Sea of Japan (East Sea). During the first half of the 1st millennium, Korea was divided between three states, Goguryeo, Baekje, and Silla, together known as the Three Kingdoms of Korea. In the second half of the 1st millennium, Silla defeated and conquered Baekje and Goguryeo, leading to the "Unified Silla" period. Meanwhile, Balhae formed in the north, superseding former Goguryeo. Unified Silla eventually collapsed into three separate states due to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Standard Length
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes.

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 , meaning 'water', with the suffix , 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. The aquarium craze was launched in early Victorian England by Gosse, who created and stocked the first public aquarium at the London Zoo in 1853, and published the first manual, ''The Aquarium: An Unveiling of the Wonders of the Deep Sea'' in 1854.Katherine C.

Macropodus
''Macropodus'' is a genus of small to medium-sized labyrinth fish native to freshwater habitats in eastern Asia. Most species are restricted to southern China (including Hong Kong and Taiwan) and Vietnam, but ''M. opercularis'' occurs as far north as the Yangtze basin, and ''M. ocellatus'' occurs north to the Amur River, as well as in Japan and Korea. In China, they are often used for fights, so they are named Chinese bettas because of their similarity to the genus ''Betta''. A few species in the genus are regularly seen in the aquarium trade, and ''M. opercularis'' has been introduced to regions far outside its native range.SeriouslyFish: Macropodus opercularis.' Retrieved 16 July 2014. Species As of 2014, the recognized species in this genus are: * '' Macropodus baviensis'' H. D. Nguyễn & V. H.
