Amphilophus Citrinellus
''Amphilophus citrinellus'' is a large cichlid fish endemic to the San Juan River (Nicaragua), San Juan River and adjacent watersheds in Costa Rica and Nicaragua. In the aquarium trade ''A. citrinellus'' is often sold under the trade name of Midas cichlid. ''A. citrinellus'' are omnivorous and their diet consists of plant material, molluscs and smaller fish. The species is closely related to, but not to be mistaken for, ''Amphilophus labiatus'', which shares the nickname red devil cichlid. Physical characteristics Midas cichlids are heavily built and are capable of standing up to any other aquarium-sized cichlid in fights over territory. They have powerful jaws, sharp teeth and a physical size advantage in comparison to other aquarium species. Therefore, the aggressivity of Midas cichlids should not be underestimated and cohabitants should be chosen carefully in an aquarium setting. Taxonomic status Considerable debate over the Taxonomy (biology), taxonomic status of ''A. citrin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lake Xiloá
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions of oceans or large l ...

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 ...

Amphilophus Astorquii
''Amphilophus'' is a genus of cichlid fishes from Central America, ranging from southern Mexico to Panama. The genus currently contains 23 species, including several that are well known from the aquarium trade. However, studies led by Oldřich Říčan in 2008 and 2016 suggested that several species within ''Amphilophus'' should be moved to the genus '' Astatheros''. Species proposed to be moved to ''Astatheros'' in 2008 were ''A. alfari'', ''A. altifrons'', ''A. bussingi'', ''A. diquis'', ''A. longimanus'', ''A. macracanthus'' (which would be the type species for ''Astatheros''), ''A. margaritifer'', ''A. rhytisma'', ''A. robertsoni'' and ''A. rostratus''. Further genetic studies led Říčan to put ''A. macracanthus'' in ''Astatheros'', but to put ''A. alfari'', ''A. altifrons'', ''A. bussingi'', ''A. diquis'', ''A. longimanus'', ''A. rhytisma'', ''A. robertsoni'' and ''A. rostratus'' within the genus '' Cribroheros''.

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...

Amphilophus Zaliosus
''Amphilophus zaliosus'' is a species of cichlid that inhabits Lake Apoyo in Nicaragua. It is known in the aquarium trade as the arrow cichlid. It is an elongate species in the Midas cichlid species complex. The arrow cichlid shares its habitat with five other recently discovered species of this complex. Genetic evidence from Apoyo supports a hypothesis that the six known species of the lake evolved via sympatric speciation. Appearance The yellow background color, common among the ''Amphilophus'' cichlids of Nicaragua, is absent in the arrow cichlid. The background color is silver to greenish gray. Breeding specimens can be entirely black. Conservation The arrow cichlid is the only endemic Lake Apoyo cichlid that has been evaluated by the IUCN. It has been rated as Critically Endangered on the IUCN Red List. Among the small body of information regarding populations of the species of this group, four other species may have smaller populations and/or ranges than this fish in Lak ...

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...
