Celestichthys
''Danio margaritatus'', the celestial pearl danio, often referred to in the aquarium trade as galaxy rasbora or ''Microrasbora'' sp. 'Galaxy',Clarke (2007b) is a small cyprinid from Myanmar. It has so far been found only in a very small area near Hopong east of Inle Lake, at an elevation of over 1,000 m (3,400 ft). Its habitat is part of the Salween basin, namely the Nam Lang and Nam Pawn Rivers. Discovered in 2006, the species quickly appeared in the aquarium trade, where its small size and bright colours made it an instant hit.Clarke (2006) Description This is a small, plump danionin with a markedly blunt snout, measuring just 2–2.5 cm standard length. The body is about three times as long as it is high. In general shape, it resembles ''Danio erythromicron'' more than any other known species. This species shows some sexual dimorphism: males have a bright-blue background color (dull blue-green in females), and their fins are more brightly colored. The tail e ...

Danionin
The danionins are a group of small, minnow-type fish belonging to the family Cyprinidae. Members of this group are mostly in the genera ''Danio'', '' Devario'', and ''Rasbora''. They are primarily native to the fresh waters of South and Southeast Asia, with fewer species in Africa. Many species are brightly coloured and are available as aquarium fish worldwide. ''Danio'' species tend to have horizontal stripes, rows of spots, or vertical bars, and often have long barbels. ''Devario'' species tend to have vertical or horizontal bars, and short, rudimentary barbels, if present at all. All danionins are egg scatterers, and breed in the rainy season in the wild. They are carnivores, living on insects and small crustaceans. Taxonomy The grouping of fish now deemed danionins has been the subject of constant research and speculation throughout the 20th century. Nearly all the fish classed within the genera ''Danio'' and ''Devario'' were originally placed in the genus ''Danio'' upon dis ...

Danio Erythromicron
''Danio erythromicron'', often known as emerald dwarf danio and emerald dwarf rasbora, is a species of cyprinid fish which is endemic to Inle Lake in Myanmar. Taxonomy and systematics In 1999, it was suggested that the species be transferred to the genus ''Danio'' based on morphological data, but it was cautioned that more research would be necessary. A phylogenetic analysis of ''Danio'' found it indeed close to that genus, but its precise placement was still indeterminable. Shortly thereafter, a new species, ''Danio margaritatus'', was described under the name ''Celestichthys margaritatus''. However, this new species was quickly moved into ''Danio'' following further analysis. Subsequent analysis of DNA sequence data showed that ''Microrasbora erythromicron'' was related to ''Danio'', and recommended moving this species to that genus. Later molecular analysis confirmed its placement within the genus, with its closest relatives being ''Danio margaritatus ''Danio margaritatus'', ...

Cyprinid
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used by ...

Danio Choprae
The glowlight danio (''Danio choprae'') is a small, schooling fish closely related to the popular zebrafish ''Danio rerio''. This should not be confused with the GloFishbr> a trademarked brand of fluorescent zebrafish that appear to glow in the dark under ultraviolet light. ''Danio choprae'' is an active danionin species that spends most of its time on mid-water levels. This species feeds on insects that have fallen into the water, aquatic insect larvae, and other small animals. In the aquarium, it accepts most foods offered, including most dry foods. It has a streamlined body marked with a brilliant orange longitudinal band and a series of vertical blue-black bars on the flanks. The fins are edged with yellow. In recent years, it has become quite widely traded as an aquarium fish, but otherwise has no commercial importance. Its common name derives from its similarity to the glowlight tetra, a South American characin only distantly related to this fish. They get on well with all o ...

Anal Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Microrasbora
''Microrasbora'' is a genus of small fishes. The generic name means "small Rasbora", however these are more closely related to the danios than rasboras. They inhabit freshwater in Myanmar and Yunnan, China. Taxonomy ''Microrasbora'', until recently, included a number of described species. '' Microrasbora erythromicron'' was first shown to be a member of the genus ''Danio ''Danio'' is a genus of small freshwater fish in the family Cyprinidae found in South and Southeast Asia, commonly kept in aquaria.

Anus
The anus (Latin, 'ring' or 'circle') is an opening at the opposite end of an animal's digestive tract from the mouth. Its function is to control the expulsion of feces, the residual semi-solid waste that remains after food digestion, which, depending on the type of animal, includes: matter which the animal cannot digest, such as bones; Summary at food material after the nutrients have been extracted, for example cellulose or lignin; ingested matter which would be toxic if it remained in the digestive tract; and dead or excess gut bacteria and other endosymbionts. Amphibians, reptiles, and birds use the same orifice (known as the cloaca) for excreting liquid and solid wastes, for copulation and egg-laying. Monotreme mammals also have a cloaca, which is thought to be a feature inherited from the earliest amniotes via the therapsids. Marsupials have a single orifice for excreting both solids and liquids and, in females, a separate vagina for reproduction. Female placenta ...

Hydrocharitaceae
Hydrocharitaceae is a flowering plant family including 16 known genera with a total of ca 135 known species (Christenhusz & Byng 2016), that including a number of species of aquatic plant, for instance the tape-grasses, the well known Canadian waterweed, and frogbit. The family includes both freshwater and marine aquatics. They are found throughout the world in a wide variety of habitats, but are primarily tropical. Description The species are annual or perennial, with a creeping monopodial rhizome with the leaves arranged in two vertical rows, or an erect main shoot with roots at the base and spirally arranged or whorled leaves. The leaves are simple and usually found submerged, though they may be found floating or partially emerse. As with many aquatics they can be very variable in shape – from linear to orbicular, with or without a petiole, and with or without a sheathing base. The flowers are arranged in a forked, spathe-like bract or between two opposite bracts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elodea
''Elodea'' is a genus of 6 species of aquatic plants often called the waterweeds described as a genus in 1803. Classified in the frog’s-bit family (Hydrocharitaceae), ''Elodea'' is native to the Americas and is also widely used as aquarium vegetation and laboratory demonstrations of cellular activities. It lives in fresh water. An older name for this genus is ''Anacharis'', which serves as a common name in North America. The introduction of some species of ''Elodea'' into waterways in parts of Europe, Australia, Africa, Asia, and New Zealand has created a significant problem and it is now considered a noxious weed in these areas. ''Elodea canadensis'', sometimes called American or Canadian water weed or pond weed, is widely known as the generic water weed. The use of these names causes it to be confused with similar-looking plants, like Brazilian elodea ('' Egeria densa'') or hydrilla (''Hydrilla verticillata''). American water weed is an attractive aquarium plant and is a g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
