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 ...

Pygmy Gourami
The pygmy gourami (''Trichopsis pumila''), also known as the sparkling gourami, is a freshwater species of gourami native to Southeast Asia. Description Pygmy gouramis can reach a length of SL. In color, they sparkle with red, green, and blue hues, and can produce an audible croaking noise using a specialised pectoral mechanism. In the right light, its eyes appear bright blue, and its arrowhead-shaped body and caudal fins reflect a rainbow of colors as it swims. Sexing is difficult, but males have red spots above the "body line" or the stripe through their body, and females spots are duller. Habitat Its native habitat is slow rivers, rice paddies, ditches and small ponds. It is most commonly found in standing not stagnant water (including waters with low oxygen levels) that has a dense cover of floating plants. The pygmy gourami can survive in these waters because of its labyrinth organ, which allows it to breathe air from the surface. Its native habitat has a pH of 6.0†...

Candling
Candling is a method used in embryology to study the growth and development of an embryo inside an egg. The method uses a bright light source behind the egg to show details through the shell, and is so called because the original sources of light used were candles. The technique of using light to examine eggs is used in the egg industry to assess the quality of edible eggs. In Plants This technique can also be used to assess the quality and development stage of certain translucent plant seeds, especially those of Lilies and their close relatives. Ripe, viable seeds have a visible embryo within them when viewed in transmitted light, so good seeds can be sorted out from the non-viable seeds and chaff, if desired. Candling is a highly useful method with certain species that germinate erratically or very slowly, as seed germination causes the embryo to enlarge. Candling can thus be used to estimate the optimal time for planting seeds that are being stratified. Care must be take ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Algae
Algae (; singular alga ) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as ''Chlorella,'' ''Prototheca'' and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to in length. Most are aquatic and autotrophic (they generate food internally) and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem that are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the ''Charophyta'', a division of green algae which includes, for example, ''Spirogyra'' and stoneworts. No definition of algae is generally accepted. One definition is that algae "have chlorophyll ''a'' as their primary photosynthetic pigment and lack a sterile covering of cells around thei ...

Brine Shrimp
''Artemia'' is a genus of aquatic crustaceans also known as brine shrimp. It is the only genus in the family Artemiidae. The first historical record of the existence of ''Artemia'' dates back to the first half of the 10th century AD from Urmia Lake, Iran, with an example called by an Iranian geographer an "aquatic dog," although the first unambiguous record is the report and drawings made by Schlösser in 1757 of animals from Lymington, England. ''Artemia'' populations are found worldwide in inland saltwater lakes, but not in oceans. ''Artemia'' are able to avoid cohabiting with most types of predators, such as fish, by their ability to live in waters of very high salinity (up to 25%). The ability of the ''Artemia'' to produce dormant eggs, known as cysts, has led to extensive use of ''Artemia'' in aquaculture. The cysts may be stored indefinitely and hatched on demand to provide a convenient form of live feed for larval fish and crustaceans. Nauplii of the brine shrimp ''Artemia' ...

Peat
Peat (), also known as turf (), is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem covers and is the most efficient carbon sink on the planet, because peatland plants capture carbon dioxide (CO2) naturally released from the peat, maintaining an equilibrium. In natural peatlands, the "annual rate of biomass production is greater than the rate of decomposition", but it takes "thousands of years for peatlands to develop the deposits of , which is the average depth of the boreal orthernpeatlands", which store around 415 gigatonnes (Gt) of carbon (about 46 times 2019 global CO2 emissions). Globally, peat stores up to 550 Gt of carbon, 42% of all soil carbon, which exceeds the carbon stored in all other vegetation types, including the world's forests, although it covers just 3% of the land's surface. ''Sphagnum'' moss, also called peat moss, is one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ichthyophthirius Multifiliis
''Ichthyophthirius multifiliis'', often termed "Ich", is a parasitic ciliate described by the French parasitologist Fouquet in 1876. Only one species is found in the genus which also gave name to the family. The name literally translates as "the fish louse with many children". The parasite can infect most freshwater fish species and, in contrast to many other parasites, shows very low host specificity. It penetrates gill epithelia, skin and fins of the fish host and resides as a feeding stage (the trophont) inside the epidermis. It is visible as a white spot on the surface of the fish but, due to its internal microhabitat, it is a true endoparasite and not an ectoparasite. It causes a disease commonly referred to as white spot disease due to the macroscopically visible trophonts (up to 1 mm in diameter) in the skin and fins. The trophont, continuously rotating, is surrounded by host cells (epidermal cells and leukocytes), producing a minute elevation of the skin. These light ...

List Of Aquarium Diseases
The following is a list of aquarium diseases. Aquarium fish are often susceptible to numerous diseases, due to the artificially limited and concentrated environment. New fish can sometimes introduce diseases to aquaria, and these can be difficult to diagnose and treat. Most fish diseases are also aggravated when the fish is stressed. Common aquarium diseases include the following: Freshwater Saltwater * ''Cryptocaryon'' (marine ich) * Marine velvet or coral reef fish disease * Anemonefish disease Both Uncategorized * ''Myxobacteriosis'' * '' Ichthyobodo'' (costia) Quarantine The goal of quarantine is to prevent problems in the main tank due to sickness. A quarantine tank should be used before to introduce any newly acquired animals in the main tank and to treat fish that are already sick. By doing this, the aquarist can avoid the spread of the disease and make it easier to treat the fish. See also *Fish diseases and parasites References Bibliography * ''En ...

Temperature
Temperature is a physical quantity that expresses quantitatively the perceptions of hotness and coldness. Temperature is measured with a thermometer. Thermometers are calibrated in various temperature scales that historically have relied on various reference points and thermometric substances for definition. The most common scales are the Celsius scale with the unit symbol °C (formerly called ''centigrade''), the Fahrenheit scale (°F), and the Kelvin scale (K), the latter being used predominantly for scientific purposes. The kelvin is one of the seven base units in the International System of Units (SI). Absolute zero, i.e., zero kelvin or −273.15 °C, is the lowest point in the thermodynamic temperature scale. Experimentally, it can be approached very closely but not actually reached, as recognized in the third law of thermodynamics. It would be impossible to extract energy as heat from a body at that temperature. Temperature is important in all fields of natur ...

Siamese Fighting Fish
The Siamese fighting fish (''Betta splendens''), commonly known as the betta, is a freshwater fish native to Southeast Asia, namely Cambodia, Laos, Myanmar, Malaysia, Indonesia, Thailand, and Vietnam. It is one of 73 species of the genus ''Betta,'' but the only one Eponym, eponymously called "betta", owing to its global popularity as a pet; ''Betta splendens'' are among the most popular aquarium fish in the world, due to their diverse and colorful Morphology (biology), morphology and relatively low maintenance. Siamese fighting fish are endemic to the central plain of Thailand, where they were first domesticated at least 1,000 years ago, among the longest of any fish. They were initially bred for aggression and subject to gambling matches akin to Cockfight, cockfighting. Bettas became known outside Thailand through King Rama III (1788-1851), who is said to have given some to Theodore Cantor, a Danish physician, zoologist, and botanist. They first appeared in the West in the lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Labyrinth Organ
The Anabantoidei are a suborder of anabantiform ray-finned freshwater fish distinguished by their possession of a lung-like labyrinth organ, which enables them to breathe air. The fish in the Anabantoidei suborder are known as anabantoids or labyrinth fish, or colloquially as gouramies. Some labyrinth fish are important food fish, and many others, such as the Siamese fighting fish and paradise fish, are popular as aquarium fish. Labyrinth organ The labyrinth organ, a defining characteristic of fish in the suborder Anabantoidei, is a much-folded supra branchial accessory breathing organ. It is formed by vascularized expansion of the epibranchial bone of the first gill arch and used for respiration in air.Pinter, H. (1986). Labyrinth Fish. Barron's Educational Series, Inc., This organ allows labyrinth fish to take in oxygen directly from the air, instead of taking it from the water in which they reside through use of gills. The labyrinth organ helps the inhaled oxygen to be abs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
