Crossocheilus Langei
''Crossocheilus langei'', also known as the red algae eater (but sold sometimes sold as "Siamese algae eater"), is a species of ray-finned fish in the genus '' Crossocheilus''. It is native to Malaysia and Sumatra. This bottom-dwelling tropical fish is found in mainland Southeast Asia. Its natural habitats are streams and rivers as well as flooded forests during the rainy season. It is often confused with the Crossocheilus oblongus, however, both are algae eaters and will behave similarly. Description The Siamese algae eater has a black horizontal stripe extending from opercle to tail. The stripe can fade to camouflage the Siamese algae eater against its surroundings. Genuine ''Crossocheilus siamensis'', (incorrect species) without maxillary barbels and with deeply fringed V-shaped upper lip are rarely encountered in the aquarium trade. The red algae eater is a species that is widely sold as "Siamese algae eater". It has a bright brownish elongate body with a slightly flat b ...

Pieter Bleeker
Pieter Bleeker (10 July 1819 – 24 January 1878) was a Dutch medical doctor, ichthyologist, and herpetologist. He was famous for the ''Atlas Ichthyologique des Indes Orientales Néêrlandaises'', his monumental work on the fishes of East Asia published between 1862 and 1877. Life and work Bleeker was born on 10 July 1819 in Zaandam. He was employed as a medical officer in the Royal Netherlands East Indies Army from 1842 to 1860, (in French). stationed in the Dutch East Indies (now Indonesia). During that time, he did most of his ichthyology work, besides his duties in the army. He acquired many of his specimens from local fishermen, but he also built up an extended network of contacts who would send him specimens from various government outposts throughout the islands. During his time in Indonesia, he collected well over 12,000 specimens, many of which currently reside at the Naturalis Biodiversity Center in Leiden. Bleeker corresponded with Auguste Duméril of Paris. His wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinoptery ...

Crossocheilus
''Crossocheilus'', also known as the fringe barbs, flying foxes, or "algae eaters", is a genus of fish in the family Cyprinidae. It is distributed in China, India, Indonesia, Malaysia and Thailand in Asia. These fish occur in several types of habitat, often fast-flowing rivers with rocky bottoms. Species There are currently 11 recognized species in this genus: * ''Crossocheilus atrilimes'' Kottelat, 2000 * ''Crossocheilus cobitis'' (Bleeker, 1854) * ''Crossocheilus elegans'' Kottelat & H. H.

Crossocheilus Oblongus
The Siamese algae-eater (''Crossocheilus oblongus'') is a species of freshwater fish in the carp family, Cyprinidae. This bottom-dwelling tropical fish is found in mainland Southeast Asia, including the Chao Phraya and Mekong basins as well as the Malay Peninsula. Its natural habitats are streams and rivers as well as flooded forests during the rainy season. The Siamese algae-eater should not be confused with the flying fox (''Epalzeorhynchos kalopterus'') or the false siamensis (''Garra cambodgiensis''), lacking the distinctive black bands of the former. Description The Siamese algae-eater has a black horizontal stripe extending from nose to tail. The stripe can quickly fade to camouflage the fish against its surroundings, which is observed during fights or stress. Genuine ''Crossocheilus siamensis'', without maxillary barbels and with deeply fringed V-shaped upper lip are rarely encountered in the aquarium trade. Siamese algae-eaters can grow up to 15 centimetres (6 ... [...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 ...

Community Tank
Community aquaria are tanks that are designed to contain more than one species of fish. Most commonly they include a variety of species that do not normally occur together in nature, for example angelfish from Brazil, swordtails from Mexico, and gouramis from South East Asia. The aim of such communities is to bring together fish that are compatible in temperament and water requirements, while using their different colours and behaviors to add interest and entertainment value. Though not usually called community tanks, most marine aquaria fit into this category too, using fish from places as diverse as the Caribbean, Red Sea, and western Pacific Ocean. Other aquarists prefer communities, called biotopes, that represent particular geographic locations, and combine fish with appropriate decorative materials including endogenous rocks and plants. The most popular of these geographically correct community tanks are those replicating the cichlid habitat of the East African Rift lakes ...

Gyrinocheilus
''Gyrinocheilus'' is the single genus in the family Gyrinocheilidae, a family of small Southeast Asian cypriniform fishes that live in fast-flowing freshwater mountain streams. The species in this genus are commonly called "algae eaters." They hold on to fixed objects using a sucker-like mouth, and, despite the name, feed on a wide range of detritus, rather than simply on algae. A "golden" variety of ''G. aymonieri'', the Chinese algae eater or "sucking loach", can be found in many pet shops and fish farms. Sucker The mouths of these fish have developed into a suckermouth, which allows the fish to cling onto objects in the fast-moving water of their habitat. They therefore stay close to the bottom, where their primary food, algae, is more readily available. Uniquely among fish, members of this family have gill slits with two openings each. Water enters through one opening, and leaves through the other. This allows the fish to breathe without having to take water in through the m ...

Epalzeorhynchos Bicolor
The red-tailed black shark (''Epalzeorhynchos bicolor''; syn. ''Labeo bicolor''), also known as the redtail shark and redtail sharkminnow, is a species of freshwater fish in the carp family, Cyprinidae. Despite its name, it is more closely related to carp. It is Endemism, endemic to Thailand and currently critically endangered, but common in aquaria, where it is prized for its deep black body and vivid red or vivid orange tail. The red-tailed black sharks seen in the aquarium trade today are all captive bred. Distribution The species is Endemism, endemic to Thailand, and was described by Hugh M. Smith in 1931 as being 'not uncommon in Bueng Boraphet and the streams which lead from it, and as being found in the Chao Phraya River as far south as Bangkok. A 1934 expedition reported catching a specimen in the Silom canal. As of 2011 it is only known at a single location in the Chao Phraya basin and has Critically Endangered status on the IUCN Red List. From 1996 until 2011 it was be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Algae Eater
Algae eater or algivore is a common name for any bottom-dwelling or filter-feeding aquatic animal species that specialize in feeding on algae and phytoplanktons. Algae eaters are important for the fishkeeping hobby and many are commonly kept by aquarium hobbyists to improve water quality. They are also important primary consumers that relay the biomass and energy from photosynthetic autotrophes up into the food web, as well as protecting the aquatic ecosystem against algae blooms. Freshwater Fish Some of the common and most popular freshwater aquarium algae eaters include: * Many loricariid catfish of South America, such as genera ''Otocinclus'', ''Ancistrus'', and ''Plecostomus'', constantly graze algae and biofilm, although many species of "plecos", which attain an adult length of over 10 inches, eat much less frequently as they near adulthood. * The Siamese algae eater (''Crossocheilus oblongus'') is a more gregarious and tolerant cyprinid that ranges up to . It is one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Algae
Red algae, or Rhodophyta (, ; ), are one of the oldest groups of eukaryotic algae. The Rhodophyta also comprises one of the largest phyla of algae, containing over 7,000 currently recognized species with taxonomic revisions ongoing. The majority of species (6,793) are found in the Florideophyceae (class), and mostly consist of multicellular, marine algae, including many notable seaweeds. Red algae are abundant in marine habitats but relatively rare in freshwaters. Approximately 5% of red algae species occur in freshwater environments, with greater concentrations found in warmer areas. Except for two coastal cave dwelling species in the asexual class Cyanidiophyceae, there are no terrestrial species, which may be due to an evolutionary bottleneck in which the last common ancestor lost about 25% of its core genes and much of its evolutionary plasticity. The red algae form a distinct group characterized by having eukaryotic cells without flagella and centrioles, chloroplasts that l ...

Audouinella
''Audouinella'', also known as black algae, is a widespread genus of red algae, found in marine and freshwater environments. The form known as "''black brush algae''" (or "''black beard algae''", ''BBA'' for short) is a particular nuisance in aquaria, since most algae eater fish and invertebrates avoid it. Description J.B. Bory de Saint-Vincent named the genus in 1823, in honour of his co-editor in the ''Dictionnaire Classique d'Histoire Naturelle'', J.V. Audouin. Black algae species are not all black; they grow as small tufts of red, brown, or black hairlike filaments on any solid surface – most dramatically in freshwater, on the edges of slow-growing leaves. Its thalli are composed of uniaxial filaments, the ends of which often contain elongate hairs. ''Audouinella'' reproduce via spores, most commonly asexually, while sexual reproduction is known in rare cases. Black algae are typically tolerant of high levels of pollution, acidity, and thrive on dissolved phosphate a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
