Pelvicachromis Taeniatus
''Pelvicachromis taeniatus'' is a species of cichlid from Benin and Nigeria that is occasionally kept as an aquarium fish. It is native to the soft-water rivers. This species can reach a length of SL. It is known to exist in a variety of geographically restricted varieties distinguished by differences in coloration. These are often given names such as "Nigerian red" or "Moliwe" that refer to the places where each variety is collected. The species ''P. taeniatus'' formerly included populations from Cameroon. A 2014 study by Lamboj, Bartel & dell’Ampio found that the Cameroon populations were a different species from the Nigeria populations, and identified the Cameroon populations as belonging to the species '' Pelvicachromis kribensis'' and '' Pelvicachromis drachenfelsi''. Lamboj, Bartel & dell’Ampio found that ''P. kribensis'', ''P. drachenfelsi'' and ''P. taeniatus'' are closely related and form a clade within the genus ''Pelvicachromis'', which they described as the "' ...

George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes. He graduated in 1876 from the Free University of Brussels (1834–1969), Free University of Brussels with a degree in natural sciences, and worked for a while at the Royal Belgian Institute of Natural Sciences, Brussels, as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the ''National Museum of Natural History (France), Muséum national d'Histoire naturelle'' in Paris and the Natural History Museum, London, British Museum in London.

Cichlid
Cichlids () are a large, diverse, and widespread family of percomorph fish in the family Cichlidae, order Cichliformes. At least 1,760 species have been scientifically described, making it one of the largest vertebrate families, with only the Cyprinidae being more speciose. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. They are native to the Neotropics, Africa (including Madagascar), the Middle East, and the Indian subcontinent, although some species have been introduced worldwide. Many cichlids, particularly tilapia, are important food fishes, while others, such as the '' Cichla'' species, are valued game fish. The family also includes many popular freshwater aquarium fish kept by hobbyists, including the angelfish, oscars, and discus. Cichlids have the largest number of endangered species among vertebrate families, most in the haplochrom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies, for data used in many areas of ichthyology, including taxonomy and fishery 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. 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 (shark Sharks are a group of elasmobranch cartilaginous fish characterized by ...

Cameroon
Cameroon, officially the Republic of Cameroon, is a country in Central Africa. It shares boundaries with Nigeria to the west and north, Chad to the northeast, the Central African Republic to the east, and Equatorial Guinea, Gabon, and the Republic of the Congo to the south. Its coastline lies on the Bight of Biafra, part of the Gulf of Guinea, and the Atlantic Ocean. Due to its strategic position at the crossroads between West Africa and Central Africa, it has been categorized as being in both camps. Cameroon's population of nearly 31 million people speak 250 native languages, in addition to the national tongues of English and French, or both.

Pelvicachromis Kribensis
''Pelvicachromis'' is a genus of small (), brightly coloured cichlids from tropical West Africa and Central Africa. They typically inhabit soft, acidic water ( pH 5.6 – 6.9). All species form monogamous pairs and use caves as spawning sites. Most are easily spawned in captivity with adequate water quality. Species There are currently 11 recognized species in this genus: * '' Pelvicachromis drachenfelsi'' Lamboj, Bartel & dell’Ampio, 2014 * '' Pelvicachromis humilis'' Boulenger, 1916 * '' Pelvicachromis kribensis'' Boulenger, 1911 * '' Pelvicachromis pulcher'' Boulenger, 1901 (Rainbow Kribensis) * '' Pelvicachromis roloffi'' Thys van den Audenaerde, 1968 * '' Pelvicachromis rubrolabiatus'' Lamboj, 2004 * '' Pelvicachromis sacrimontis'' Paulo, 1977 (Often mislabelled as ''P. pulcher'') * '' Pelvicachromis signatus'' Lamboj, 2004 * '' Pelvicachromis silviae'' Lamboj, 2013 * '' Pelvicachromis subocellatus'' Günther, 1872 * ''Pelvicachromis taeniatus'' Boulenger, 19 ...

Pelvicachromis Drachenfelsi
''Pelvicachromis drachenfelsi'' is a freshwater fish of the cichlid family, endemic to the Wouri River system near the town of Yabassi in Cameroon. Taxonomy Specimens from this locality were originally believed to be the same species as ''Pelvicachromis taeniatus'' with small regional variations in colour but a study by Lamboj, Bartel & dell’Ampio in 2014 would show that it was genetically separate from ''P. taeniatus'' and shared a closer common ancestor to ''Pelvicachromis kribensis''. The three distinctly described species of ''P. taeniatus'', ''P. kribensis,'' and ''P. drachenfelsi'' all share a clade together and are referred to as the ''P. taeniatus'' group. The specific name Specific name may refer to: * in Database management systems, a system-assigned name that is unique within a particular database In taxonomy, either of these two meanings, each with its own set of rules: * Specific name (botany), the two-part (bino ... was bestowed to German aquarist Ernst-Otto von ...

Pelvic Fin
Pelvic fins or ventral fins are paired fins located on the ventral (belly) surface of fish, and are the lower of the only two sets of paired fins (the other being the laterally positioned pectoral fins). The pelvic fins are homologous to the hindlimbs of tetrapods, which evolved from lobe-finned fish during the Middle Devonian. Structure and function Structure In actinopterygians, the pelvic fin consists of two endochondrally-derived bony girdles attached to bony radials. Dermal fin rays ( lepidotrichia) are positioned distally from the radials. There are three pairs of muscles each on the dorsal and ventral side of the pelvic fin girdle that abduct and adduct the fin from the body. Pelvic fin structures can be extremely specialized in actinopterygians. Gobiids and lumpsuckers modify their pelvic fins into a sucker disk that allow them to adhere to the substrate or climb structures, such as waterfalls. In priapiumfish, males have modified their pelvic structures into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fishkeeping
Fishkeeping is a popular hobby, practiced by aquarists, concerned with keeping fish in a home aquarium or garden pond. It is a practice that encompasses the art of maintaining one's own aquatic ecosystem, featuring a lot of variety with various water systems, all of which have their own unique features and requirements. Fishkeeping primarily serves as a token of appreciation and fascination for marine life and the environment that surrounds such, along with other purposes such as the pisciculture, piscicultural fishkeeping industry, serving as a branch of agriculture, being one of the most widespread methods of cultivating fish for commercial profit. Origins of fishkeeping Fish have been raised as food in pools and ponds for thousands of years. Brightly colored or tame specimens of fish in these pools have sometimes been valued as pets rather than food. Many cultures, ancient and modern, have kept fish for both functional and decorative purposes. Ancient Sumerians kept wild-c ...
