Croaking Gourami
The croaking gourami (''Trichopsis vittata'') is a species of small freshwater labyrinth fish of the gourami family. They are native to still waters in Southeast Asia and are distributed worldwide via the aquarium trade. Croaking gouramis are capable of producing a "croaking" noise using their pectoral fins. General Croaking gouramis can reach an average size of about 5 centimeters, though some individuals can grow as large as 6 or 7 centimeters. Coloration is highly variable, ranging from pale brown and green to dark purple with black or red spots on the fins. 2-4 brown or black stripes or rows of spots are present on their sides. Median fins have a thin iridescent blue coloration on their edges. The iris of the eye is bright blue or purple. Females tend to be paler than males, have a slightly rounded dorsal fin and a shorter anal fin. Most croaking gouramis live for about 2 years but with proper care can live as long as 5 in an aquarium setting. They are native to stillwater ...

Taxa Named By Ingo Schindler
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Of Thailand
Fish are Aquatic animal, aquatic, craniate, gill-bearing animals that lack Limb (anatomy), limbs with Digit (anatomy), digits. Included in this definition are the living hagfish, lampreys, and Chondrichthyes, cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a vertebrate, true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed placodermi, external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Betta
''Betta'' is a large genus of small, active, often colorful, freshwater ray-finned fishes, in the gourami family (Osphronemidae). The best known ''Betta'' species is ''B. splendens,'' commonly known as the Siamese fighting fish and often kept as an aquarium pet. Characteristics All ''Betta'' species are small fishes, but they vary considerably in size, ranging from under 2.5 cm (1 in) total length in ''B. chanoides'' to 14 cm (5.5 in) in the Akar betta (''B. akarensis''). Bettas are anabantoids, which means they can breathe atmospheric air using a unique organ called the labyrinth. This accounts for their ability to thrive in low-oxygen water conditions that would kill most other fish, such as rice paddies, slow-moving streams, drainage ditches, and large puddles. The bettas exhibit two kinds of spawning behaviour: some build bubble nests, such as ''B. splendens'', while others are mouthbrooders, such as ''B. picta''. The mouthbrooding species are sometim ...

Mouthbrooder
Mouthbrooding, also known as oral incubation and buccal incubation, is the care given by some groups of animals to their offspring by holding them in the mouth of the parent for extended periods of time. Although mouthbrooding is performed by a variety of different animals, such as the Darwin's frog, fish are by far the most diverse mouthbrooders. Mouthbrooding has evolved independently in several different families of fish. Mouthbrooding behaviour Paternal mouthbrooders are species where the male looks after the eggs. Paternal mouthbrooders include the arowana, various mouthbrooding bettas and gouramies such as ''Betta pugnax'', and sea catfish such as ''Ariopsis felis''. Among cichlids, paternal mouthbrooding is relatively rare, but is found among some of the tilapiines, most notably the black-chin tilapia ''Sarotherodon melanotheron''. In the case of the maternal mouthbrooders, the female takes the eggs. Maternal mouthbrooders are found among both African and South American ci ...

Fish Measurement
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. Total length meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parosphromenus Paludicola
''Parosphromenus'' is a genus of gouramies native to freshwater in Southeast Asia. All species are highly specialized peat swamp inhabitants native to southeast Asia, and the males are usually brightly colored in breeding dress; however, their need for soft, acidic water and live food prohibits the genus from becoming popular aquarium fish. Species The currently recognized species are: * '' Parosphromenus alfredi'' Kottelat & P. K. L. Ng, 2005 * '' Parosphromenus allani'' B. Brown, 1987 * '' Parosphromenus anjunganensis'' Kottelat, 1991 * '' Parosphromenus barbarae'' * '' Parosphromenus bintan'' Kottelat & P. K. L.

Hardness Of Water
Hard water is water that has high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone, chalk or gypsum, which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates. Hard drinking water may have moderate health benefits. It can pose critical problems in industrial settings, where water hardness is monitored to avoid costly breakdowns in boilers, cooling towers, and other equipment that handles water. In domestic settings, hard water is often indicated by a lack of foam formation when soap is agitated in water, and by the formation of limescale in kettles and water heaters.World Health OrganizatioHardness in Drinking-Water 2003 Wherever water hardness is a concern, water softening is commonly used to reduce hard water's adverse effects. Origins Natural rainwater, snow and other forms of precipitation typically have low concentrations of multivalent cations such as calcium and magne ...

Cryptocoryne Cordata
''Cryptocoryne'' is a genus of aquatic plants from the family Araceae. The genus is naturally distributed in tropical regions of India, Southeast Asia and New Guinea. The typical habitats of ''Cryptocoryne'' are mostly streams and rivers with not too rapidly flowing water, in the lowland forest. They also live in seasonally inundated forest pools or on river banks submerged only at high water. Although the proper scientific name of the genus is ''Cryptocoryne'', they are commonly referred to as crypts. The English name "water trumpet" refers to their inflorescence, a spadix enclosed by a spathe (typical for the whole family), which resembles a trumpet. The first ''Cryptocoryne'' species was described in 1779 as ''Arum spirale'' by Retzius. The genus was described by Friedrich Ernst Ludwig von Fischer in 1828. However, the scientific classification of ''Cryptocoryne'' species is very complicated and there are different opinions about it. ''Lagenandra'' is another genus closely ...
