Vieja Melanurus
''Vieja melanurus'', the quetzal cichlid, redhead cichlid or firehead cichlid, is a species of cichlid that is native to the Lake Petén system, the Grijalva– Usumacinta River basin and other Atlantic river drainages in southern Mexico, Belize and Guatemala, with introduced populations in a few other countries. It typically inhabits slow-moving or standing waters such as rivers, lakes and lagoons; although primarily a freshwater fish, it may occur in slightly brackish habitats. It is popular in the aquarium trade, where often listed under the synonym ''V. synspila/synspilum''. It is almost entirely herbivorous, but may also take small animal prey. ''V. melanurus'' can reach a total length 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.

Albert Günther
Albert Karl Ludwig Gotthilf Günther , also Albert Charles Lewis Gotthilf Günther (3October 18301February 1914), was a German-born British zoologist, ichthyologist, and herpetologist. Günther is ranked the second-most productive reptile taxonomist (after George Albert Boulenger) with more than 340 reptile species described. Early life and career Günther was born in Esslingen in Swabia ( Württemberg). His father was a ''Stiftungs-Commissar'' in Esslingen and his mother was Eleonora Nagel. He initially schooled at the Stuttgart Gymnasium. His family wished him to train for the ministry of the Lutheran Church for which he moved to the University of Tübingen. A brother shifted from theology to medicine, and he, too, turned to science and medicine at Tübingen in 1852. His first work was "''Ueber den Puppenzustand eines Distoma''" (On the pupal state of ''Distoma''). He graduated in medicine with an M.D. from Tübingen in 1858, the same year in which he published a handbook ...

Synonym (taxonomy)
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The Botanical nomenclature, botanical and Zoological nomenclature, zoological codes of nomenclature treat the concept of synonymy differently. * In nomenclature, botanical nomenclature, a synonym is a Binomial nomenclature, scientific name that applies to a taxon that now goes by a different scientific name. For example, Carl Linnaeus, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different Binomial nomenclature, binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved f ...

Fish Of Mexico
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolve through the Paleozoic, diversifying into many forms. The earliest fish wi ...

Vieja
''Vieja'' is a genus of cichlid fish from Central America and Mexico. The majority of the species are freshwater fish found in stagnant or slow-moving waters of southern Mexico to El Salvador, but ''V. maculicauda'', which also occurs in brackish waters, ranges south to Panama. They are high-bodied cichlids that reach lengths of up to depending on the exact species. ''Vieja'' feed mostly on vegetable matter, but may also take small invertebrates. Taxonomy and species Historically, ''Vieja'' was included in ''Cichlasoma''. Once recognized as its own genus, it sometimes included most of the superficially similar, relatively large and high-bodied cichlids of Central America and southern Mexico, but several of these are now considered to belong to separate genera: ''Chuco (fish), Chuco'', ''Cincelichthys'', ''Isthmoheros'', ''Kihnichthys'', ''Maskaheros'' and ''Montecristo cichlid, Oscura'' (''Oscuro'' might still be better merged with ''Vieja'', but this remains unconfirmed).

Flowerhorn Cichlid
Flowerhorn cichlids are ornamental aquarium fish noted for their vivid colors and the distinctively shaped heads for which they are named. Their head protuberance is formally called a Nuchal lines, nuchal hump. Like blood parrot cichlids, they are Cichlid#Hybrids and selective breeding, hybrids that exist in the wild only because of their Fishkeeping#Invasive species, release. Flowerhorns first emerged for sale on the aquarium market in Malaysia in the late 1990s and soon became popular in many countries in Asia. They are commonly kept by hobbyists in the US, Asia, and Europe. Numerous cast-off flowerhorns have been released to the wild, especially in Singapore and Malaysia, where they have become an Invasive species, invasive pest animal. Their importation is banned in Australia. Origin Flowerhorn breeding dates to 1993. Taiwanese and Malaysian peoples admired fish with protruding heads, known as 'giant gourami, kaloi' or 'warships', found in the western part of the nation. Th ...

Blood Parrot Cichlid
The Blood Parrot Cichlid (''Amphilophus citrinellus'' × ''Vieja melanurus''), or parrot cichlid, is a Hybrid (biology), hybrid species of fish in the family Cichlidae. The fish was first bred in Taiwan around 1986. Blood parrots should not be confused with other parrot cichlid (other), parrot cichlids or salt water parrotfish (family Scaridae). Natural colors of the fish are red, yellow, and grey: other colors are Painted fish, injected by breeders. Because this hybrid cichlid has various anatomy, anatomical deformity, deformities, controversy exists over the ethics of creating the blood parrot. One deformity is its mouth, which has only a narrow vertical opening. This makes blood parrots somewhat harder to feed and potentially vulnerable to malnutrition. The fish is known to be semi-aggressive. Despite its deformity, it can hold its own in a fight, and will prey on any small fish that can fit in its mouth. Description Blood parrots are often bright orange in colora ...

Total Length
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 a ...
