Cichlids
Cichlids are fish from the family (biology), family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses (Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. The closest living relative of cichlids is probably the Pholidichthys leucotaenia, convict blenny, and both families are classified in the 5th edition of ''Fishes of the World'' as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been Binomial nomenclature, scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain Undescribed taxon, undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. Many cichlids, particularly tilapia, are important food fishes, while others, such as the ''Cichla'' spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cichla
Peacock bass or Brazilian tucunaré are large freshwater cichlids of the genus ''Cichla''. These are diurnal predatory fishes native to the Amazon and Orinoco basins, as well as rivers of the Guianas, in tropical South America. They are sometimes referred to in English by their Brazilian name ''tucunaré'' or their Spanish name ''pavon''. Despite the common name and their superficial similarity, they are not closely related to other fish known as bass, such as the North American largemouth bass (''Micropterus salmoides''). Peacock bass are important food fish and also considered valuable game fish. This has resulted in their accidental (escapees from fish farms) or deliberate (release by fishers) introduction to regions outside their native range, both elsewhere in South America, and in warm parts of North America and Asia. Singles have been caught elsewhere, including Australia, but do not appear to have become established there. Where established as an introduced species, t ...

Astronotus Ocellatus
The oscar (''Astronotus ocellatus'') is a species of fish from the cichlid family known under a variety of common names, including tiger oscar, velvet cichlid, and marble cichlid. In tropical South America, where the species naturally resides, ''A. ocellatus'' specimens are often found for sale as a food fish in the local markets. The fish has been introduced to other areas, including India, China, Australia, and the United States. It is considered a popular aquarium fish in Europe and the U.S. Taxonomy The species was originally described by Louis Agassiz in 1831 as '' Lobotes ocellatus'', as he mistakenly believed the species was marine; later work assigned the species to the genus ''Astronotus''. The species also has a number of junior synonyms: ''Acara compressus'', ''Acara hyposticta'', ''Astronotus ocellatus zebra'', and ''Astronotus orbiculatus''. Description ''A. ocellatus'' examples have been reported to grow to about in length and in weight. The wild-caught forms of ...

Paratilapiinae
''Paratilapia'' is a genus of cichlids generally restricted to Madagascar. These are large, dark cichlids densely covered in light spots. An additional very poorly known species from the Congo River basin in mainland Africa is sometimes also placed in the genus, but this is highly questionable and arguably it is better placed in the "wastebasket genus" ''Haplochromis'' for the time being.Greenwood (1979). ''Towards a phyletic classification of the 'genus' Haplochromis (Pisces, Cichlidae) and related taxa.'' Bulletin of the British Museum (Natural History) Zoology 35(4): 265-322 Taxonomy Phylogenetic analyses of DNA sequence and morphological data have hitherto been unable to resolve the relationships of the genus to satisfaction. For example, sequence data from mtDNA 16S rRNA and COI disagree regarding its placement, (2004): Molecular phylogeny and biogeography of the Malagasy and South Asian cichlids (Teleostei: Perciformes: Cichlidae).

Fishkeeping
Fishkeeping is a popular hobby, practiced by aquarists, concerned with keeping fish in a home aquarium or garden pond. There is also a piscicultural fishkeeping industry, serving as a branch of agriculture. 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-caught fish in ponds, before preparing them for meals. Depictions of the sacred fish of Oxyrhynchus kept in captivity in rectangular temple pools have been found in ancient Egyptian art. Similarly, Asia has experienced a long history of stocking rice paddies with freshwater fish suitable for eating, including various types of catfish and cyprinid. Selective breeding of carp into today's popular and completely domesticated koi and fancy goldfish b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heterochromidinae
''Heterochromis'' is a genus of cichlid fish in the order Perciformes. It is the only genus of the subfamily Heterochromidinae, and contains a single species, ''Heterochromis multidens'', which is endemic to the Congo River Basin in Central Africa Central Africa is a subregion of the African continent comprising various countries according to different definitions. Angola, Burundi, the Central African Republic, Chad, the Democratic Republic of the Congo, the Republic of the Congo, .... The relationships of ''Heterochromis'' to other cichlids have long been controversial, with several morphological features suggesting that it is more closely related to American cichlids than to other African species.Kullander SO (1998) A phylogeny and classification of the South American Cichlidae (Teleostei: Perciformes).

Tilapia
Tilapia ( ) is the common name for nearly a hundred species of cichlid fish from the coelotilapine, coptodonine, heterotilapine, oreochromine, pelmatolapiine, and tilapiine tribes (formerly all were "Tilapiini"), with the economically most important species placed in the Coptodonini and Oreochromini. Tilapia are mainly freshwater fish inhabiting shallow streams, ponds, rivers, and lakes, and less commonly found living in brackish water. Historically, they have been of major importance in artisanal fishing in Africa, and they are of increasing importance in aquaculture and aquaponics. Tilapia can become a problematic invasive species in new warm-water habitats such as Australia, whether deliberately or accidentally introduced, but generally not in temperate climates due to their inability to survive in cold water. Tilapia has been the fourth-most consumed fish in the United States since 2002. The popularity of tilapia came about due to its low price, easy preparation, and ...

Pseudocrenilabrinae
The Pseudocrenilabrinae are a subfamily in the cichlid family of fishes to which, according to a study from 2004, includes all the Middle Eastern and African cichlids with the exception of the unusual '' Heterochromis multidens'' and the Malagasy species. This subfamily includes more than 1,100 species. Previous authors recognized additional African subfamilies, e.g. the Tilapiinae of Hoedeman (1947), Tylochrominae of Poll (1986), or Boulengerochrominae of Tawil (2001). To this subfamily belong the cichlids from the African Great Lakes, such as the utaka and mbuna in Lake Malawi, and various species from Lake Victoria and Lake Tanganyika. The Pseudocrenilabrinae tribes Haplochromini and Oreochromini are widespread in Africa and also found in the Middle East, while Chromidotilapiini, Hemichromini and Tylochromini are primarily West and Central African. The remaining tribes are largely or entirely restricted to Lake Tanganyika. Systematics Apart from the tribes mentioned in th ...

Cichlinae
The Cichlinae are a subfamily of fishes in the cichlid family, native to South America. This subfamily consists of approximately 117 described species as of July 2017. Some authors have suggested that the Cichlinae encompasses all of the Neotropical Cichlids and found the taxon to be monphyletic and to be divided into seven tribes: Astronotini, Chaetobranchini, Cichlasomatini, Cichlini, Geophagini, Heroini, and Retroculini. In this system the Geophaginae plus the Chaetobranchini were recovered as the sister taxon to the clade consisting of the Heroini plus the Cichlatsomatini, these latter two being referred to as the subfamily Cichlasomatinae in some classifications, while the monogeneric Astronotini was a sister taxon to these four, while the Cichlini and Retroculini made up a sister clade of the other five. Tribes The following tribes make up the subfamily Cichlinae: * Cichlini * Retroculini * Astronotini * Chaetobranchini * Geophagini * Cichlasomatini * Heroini ...

Freshwater Angelfish
''Pterophyllum'' is a small genus of freshwater fish from the family Cichlidae known to most aquarists as angelfish. All ''Pterophyllum'' species originate from the Amazon Basin, Orinoco Basin and various rivers in the Guiana Shield in tropical South America. The three species of ''Pterophyllum'' are unusually shaped for cichlids being greatly laterally compressed, with round bodies and elongated triangular dorsal and anal fins. This body shape allows them to hide among roots and plants, often on a vertical surface. Naturally occurring angelfish are frequently striped transversely, colouration which provides additional camouflage. Angelfish are ambush predators and prey on small fish and macroinvertebrates. All ''Pterophyllum'' species form monogamous pairs. Eggs are generally laid on a submerged log or a flattened leaf. As is the case for other cichlids, brood care is highly developed. ''Pterophyllum'' should not be confused with marine angelfish, perciform fish found on shall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and 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 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 external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...
