Neocaridina Davidi
''Neocaridina davidi'' is a freshwater shrimp originating from eastern China and northern Taiwan and introduced in the rest of Taiwan, Japan, and Hawaii, which is commonly kept in aquaria. The natural coloration of the shrimp is green-brown. There are a wide range of colors such as red, yellow, orange, green, blue, violet, black, etc., however, the red morph is more frequently sold. The density of coloration on adult shrimp, dependent on breeding, determines their sale price and "quality" (grading). This "quality" is purely aesthetic, as the size, behavior and other characteristics of the animal are more or less equal across varieties. Full-grown shrimp reach about long. They prefer clean water, with a pH of 6.5-8, and a temperature of They are most comfortable at . ''N. davidi'' shrimp are omnivores that may live 1–2 years. These shrimp have previously been classified as ''Neocaridina heteropoda'' and ''Neocaridina denticulata sinensis'', however are now known as ''Neoc ...

Fresh Water
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh ...

Blanching (cooking)
Blanching is a cooking process in which a food, usually a vegetable or fruit, is scalded in boiling water, removed after a brief, timed interval, and finally plunged into iced water or placed under cold running water (known as shocking or refreshing) to halt the cooking process. Blanching foods helps reduce quality loss over time. People often use blanching as a treatment prior to freezing, drying, or canning—heating vegetables or fruits to inactivate enzymes, modify texture, remove the peel, and wilt tissue. The inactivation of enzymes preserves color, flavor, and nutritional value. The process has three stages: preheating, blanching, and cooling. The most common blanching methods for vegetables/fruits are hot water and steam, while cooling is either done using cold water or cool air. Other benefits of blanching include removing pesticide residues and decreasing microbial load. Drawbacks to the blanching process can include leaching of water-soluble and heat sensitive nutrie ...

Killifish
A killifish is any of various oviparous (egg-laying) cyprinodontiform fish (including families Aplocheilidae, Cyprinodontidae, Fundulidae, Profundulidae and Valenciidae). All together, there are 1,270 species of killifish, the biggest family being Rivulidae, containing more than 320 species. As an adaptation to living in ephemeral waters, the eggs of most killifish can survive periods of partial dehydration. Many of the species rely on such a diapause, since the eggs would not survive more than a few weeks if entirely submerged in water. The adults of some species, such as ''Kryptolebias marmoratus'', can additionally survive out of the water for several weeks. Most killies are small fish, from , with the largest species growing to just under . The word ''killifish'' is of uncertain origin, but is likely to have come from the Dutch ''kil'' for a kill (small stream). Although ''killifish'' is sometimes used as an English equivalent to the taxonomical term ''Cyprinodontidae'', s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platy (fish)
Platy is a common name of freshwater fish in the genus ''Xiphophorus'' that lacks a "sword" at the bottom of their tails. Both species are livebearers, similar to other fish of the family Poeciliidae, such as the guppy and molly. Platies are native to the east coast of Central America and southern Mexico. The two species, the southern platyfish and the variatus platy, have been interbred to the point where they are difficult to distinguish. Most platies now sold in aquariums are hybrids of both species. Platy The platy (''Xiphophorus maculatus'') grows to a maximum overall length of 7.0 cm (2.8 in). Sexual dimorphism is slight, the male's caudal fin being more pointed. The anal fin of the male fish has evolved into a gonopodium, a stick-shaped organ used for reproduction. The female southern platyfish's anal fin is fan-shaped. Wild varieties are drab in coloration, lacking the distinctive dark lateral line common to many ''Xiphophorus'' species. Platies can ...

Dwarf Gouramis
The dwarf gourami (''Trichogaster lalius'') is a species of gourami native to South Asia. Distribution and habitat The dwarf gourami is native to Pakistan, India and Bangladesh. However, it has also been widely distributed outside of its native range. It inhabits slow-moving waters in rivulets, streams and lakes, occurring in areas with plentiful vegetation. Appearance and anatomy This species can reach a length of TL. Male dwarf gouramis in the wild have diagonal stripes of alternating blue and red colors; females are a silvery color. Besides the difference in color, the sex can be determined by the dorsal fin. The male's dorsal fin is pointed, while the female's is rounded or curved. They carry touch-sensitive cells on their thread-like pelvic fins. Dwarf gouramis sold in fish stores may also be solid colors (e.g., powder blue dwarf gourami or red flame variety) which are nothing but captive bred color morphs of the same species. Similar to the archerfish, the dwarf gourami ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otocinclus
''Otocinclus'' is a genus of catfish in the family Loricariidae native to South America, commonly known as "dwarf suckers" or "otos". This genus, like other loricariids, is characterized by rows of armour plating covering the body, as well as the underslung suckermouth. They are generally small in size; ''O. tapirape'' is the smallest of the species (2.4 cm), while ''O. flexilis'' is the biggest (5.5 cm). These species have adaptations that allow them to breathe air. A duct forms at the junction between the esophagus and the stomach and expands into an enlarged, ring-like diverticulum, characteristic of this genus, which allows air-breathing.Armbruster, J.W. (1998)Modifications of the Digestive Tract for Holding Air in Loricariid and Scoloplacid Catfishes.''Copeia, 1998 (3): 663–675.'' ''Otocinclus'' are popular aquarium fish, and they are often purchased as algae eaters. It is difficult to breed them in captivity, and only wild caught ''Otocinclus'' are available to h ...

Dwarf Corydoras
The dwarf corydoras (''Corydoras hastatus''), dwarf catfish, tail spot pygmy catfish, or micro catfish is a tropical freshwater fish belonging to the subfamily Corydoradinae of the family Callichthyidae. It originates in inland waters in South America, and is found in the Amazon River and Paraguay River basins in Argentina, Bolivia, and Brazil. The specific epithet ''hastatus'' means ''with a spear'', in reference to the spearhead-like spot on the tail root. Physical appearance The body of ''Corydoras hastatus'' is typically more elongated than other ''Corydoras'' species. Its body is a translucent white to olive color, with a thin dark stripe on the sides from behind the gill cover to the root of the tail, and a whitish belly. It has a white crescent at the base of the tail surrounding a black spot. The fish will grow in length up to 1.4 inches (3.5 cm), but 1.0 inch (2.5 cm) is more typical. Males are smaller, more slender and have a more pointed dorsal fin than fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cardinal Tetra
The cardinal tetra (''Paracheirodon axelrodi'') is a freshwater fish of the family Characidae of order Characiformes. It is native to the upper Orinoco and Negro Rivers in South America. Growing to about total length, the cardinal tetra has the striking iridescent blue line characteristic of the genus '' Paracheirodon'' laterally bisecting the fish, with the body below this line being vivid red in color, hence the name " cardinal tetra". The cardinal tetra's appearance is similar to that of the closely related neon tetra, with which it is often confused; the neon's red coloration extends only about halfway to the nose, and the neon's blue stripe is a less vibrant blue. The cardinal tetra is a very popular aquarium fish, but is less widespread than the neon tetra because until recently, it was difficult to breed in captivity. However, many breeders are now producing the fish; in most cases, one can determine if the cardinal tetra is bred or wild-caught due to damaged fins on ...

Neon Tetra
The neon tetra (''Paracheirodon innesi'') is a Freshwater fish of the characin family (family Characidae) of order Characiformes. The type species of its genus, it is native to blackwater and clearwater streams in the Amazon basin of South America. Its bright colouring makes the fish visible to conspecifics in the dark blackwater streams, and is also the main reason for its popularity among freshwater fish hobbyists, with neon tetras being one of the most widely kept tropical fish in the world. Range and habitat The neon tetra is found in the western and northern Amazon basin in southeastern Colombia, eastern Peru, and western Brazil. It lives in waters with a temperature between and pH 4–7.5. It has a preference for acidic blackwater streams, but also occurs in transparent clearwater streams. It is not found in the whitewater rivers. UN FAO considers ''P. innesi'' an introduced species in Singapore and the United States. FAO considers its introduction to Singapore to ...

Harlequin Rasbora
The harlequin rasbora (''Trigonostigma heteromorpha'') is a small fish in the family Cyprinidae. The species became an instant favorite among aquarists after its introduction in the early 1900s and is the best known and most widely kept species among the rasboras."Exotic Aquarium Fishes" by Dr. William T. Innes, Innes Publishing Co, Philadelphia, 1935 In 1935, an image of a trio of harlequin rasboras, stamped in 14k gold, would grace the cover of the first edition of William T. Innes's classic ''Exotic Aquarium Fishes'' and would remain so through all 19 editions. Etymology and taxonomy The species was originally classified into the genus ''Rasbora'', and given the specific name ''heteromorpha'' (Greek, "differently shaped") to alludes to the fact that its body shape differed from other members of that genus. The common name alludes to the black triangular patch on the body, reminiscent of the patterns found on the costume of a harlequin. Description The harlequin rasbora is a f ...

Ember Tetras
An ember, also called a hot coal, is a hot lump of smouldering solid fuel, typically glowing, composed of greatly heated wood, coal, or other carbon-based material. Embers (hot coals) can exist within, remain after, or sometimes precede, a fire. Embers are, in some cases, as hot as the fire which created them. They radiate a substantial amount of heat long after the fire has been extinguished, and if not taken care of properly can rekindle a fire that is thought to be completely extinguished and can pose a fire hazard. In order to avoid the danger of accidentally spreading a fire, many campers pour water on the embers or cover them in dirt. Alternatively, embers can be used to relight a fire after it has gone out without the need to rebuild the fire – in a conventional fireplace, a fire can easily be relit up to 12 hours after it goes out, provided that there is enough space for air to circulate between the embers and the introduced fuel. They are often used for cooking, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
