Cichlid Essays

The Poor Man’s Moorish Idol is ideally kept in a tank that has at least 200 gallons of Water. This is because the fish does well in a well spaced environment. Also, due to the need for a healthy exchange of gas, the Poor Man’s Moorish Idol must not be cramped with so many other species in a tank. This fish requires a good waste disposal system. Most tank owners resort to the use of a good filtration system. It is not out of place to state that the Poor Man’s Moorish Idol generates a lot of waste

The Red Snapper is also known as Lutjanus campechanus, they are pink to a red color (Louisiana Fisheries). They are commonly known as the North American Red Snapper, Snapper, Genuine Red Snapper. Their color starts to fade off under their bellies (Louisiana Fisheries). Some key characteristics are their red eyes, and their anal fin pointed than rounded. (Louisiana Fisheries). They can be found in the Gulf of Mexico and the Western Gulf (Louisiana). They can weight about anywhere ranging from 10-50

Kautt, Gonzalo Machado-Schiaffino, and Axel Meyer at the University of Konstanz in Germany analyzed the genomes of endemic species of Midas cichlids in two Nicaraguan lakes. The purpose of the experiment was to determine the manner and timeline by which these populations of fish diverged. The researchers studied organisms belonging to the species complex of cichlid fish, Amphilophus. These fish live in two isolated crater lakes, Lake Apoyo and Xiloa, and are endemic to the area. Physiology such as body

Here again, coral sand can be used to buffer the water. Some cichlids from this area are Neolamprologus multifasciatus, Neolamprologus brevis, N. occellatus, N. mealegrise, N. caudopunctatus, N. signatus, Altolamprologus compressiceps and A. calvus. An open water biotope should provide plenty of open water to swim around. Unlike most other Lake Tanganyika species, males cichlids from this environment will not need any decor, rocks or sand to mark their territories. However

component of the fish population. Until the late 1970s the biomass composition of the lake remained relatively constant, but in the middle 1980s, a survey of the lake revealed a sudden and unexpected change, a total reverse in biomass compositions. Cichlid numbers had decreased dramatically and only consisted of 1% of the total fish weight in the lake, while the Nile Perch had suddenly increased to constitute 80%. This large increase in numbers of the Nile Perch may have been caused due to the advantages

based on the presence or absence of neighbors (Hellman & Hamilton 2014). It was predicted that the cichlids would increase their defense when neighbors were present with the subordinates being especially sensitive to their presence and also that defense against predators would be higher when unfamiliar neighbors were around versus familiar ones (Hellman & Hamilton

So, the Red Devil Cichlid fish, the Tomcod fish living in the Hudson River, and the lizards on the Iron Cay Island all produced similar traits in their population to increase their chance of survival. In all three articles, experiments were done researching how each species

Internship questions What do you hope to gain from an internship with the New England Aquarium? My ultimate career goal is to work with marine animals at an aquarium and help build public awareness of conservation issues. I hope this internship will provide me with real-world experience at an aquarium and connections with professionals in the field to help me reach that goal. I also want to get more hands-on experience working with marine life and enhance my skills in interacting with visitors

One day while Hades was doing whatever he usually does (sitting on a throne) a random dead person waltz in and started screaming about some unholy beast. That sounded right up his alley so he punishes the person by making them be tortured every day. So hades (flown?) the way to the area the beast was reported. The beast was a cyclops picking up houses (Does The Underworld have houses for the dead? Oh well, It's in the myth.” and eating dead people so they will forever live in the beast's stomach

Tilapia is the generic name of a group of cichlids endemic to Africa. Tilapia has become one of the most commonly eaten fish in North America. It is currently the fourth most frequently eaten fish in the United States. It is the third most popular farm raised seafood. Part of the popularity of tilapia stems from the fact that it is easily farmed. This makes it more economical. It is also fairly mild in taste and is easy to prepare. Tilapia is a fresh water fish but has the ability to survive

Charles Darwin was a naturalist born in 1809. He set off on a five year voyage on a ship called the HMS beagle. On this voyage he collected several things including birds, fossils and plants. He went to many different places on this journey, but there were a few places that he took the most interest in. These places were the Galapagos Islands and also South America. In these places he discovered many different things. Some of these thing include the theory of evolution. With Darwin’s theory of

Proper Freshwater Angelfish Care and Keeping When taking proper care of freshwater Angelfish it is important that the aquarium owner understands the basic needs of these fish. The fish keeper should be familiar with aquariums, water quality, water oxygen levels, water temperature and water filtration. Understanding the basics of these topics will help an aquarium owner to maintain a healthy aquarium environment that will encourage breeding. It is important that the home aquarium is adequate size

Introduction Evolution is a slow and gradual process that occurs over a long period of time. It is a very controversial topic that relies on a number of assumptions though it is considered by most to be the best explanation of life on earth. Many people believe that God created the earth, often referred to as ‘intelligent design’. Darwin was the keystone for the theory of evolution. He was one of the first people to study it in depth, and the first person to publish accurate scientific research

products such as nitrogen and phosphorous released from the agriculture sector, and also the mineral deposition from industry. Ozone layer is depleted due chlorofluorohydrocarbons and some other chemicals released into the atmosphere, which permits penetration of ultraviolet light, which can be detrimental for biological organisms such as marine plankton communities (Sivasakthivel and Reddy, 2011). Introduced species / biological invasions Globally, impacts of invasive alien species (IAS) are

The data in both sets seem to support the hypothesis that when the number and type of predators is increased, the guppies become more drab. Instead of just testing the bright guppies with these variables, drab guppies were tested as well to insure accurate representation. The first trials data were consistent with the hypothesis, the percentage of bright guppies stayed stayed about the same when the amount of predators was low. In trial two more predators was introduced therefore the percentage of

Speciation was Darwin’s “mystery of mysteries”. Speciation: the process of one species splitting into two or more species. Microevolution is a change below the species level while macroevolution is a change above the species level. Species: group of populations whose members can interbreed in nature and produce viable and fertile offspring, but do not produce viable and fertile offspring with members of other groups. Reproductive isolation is required for the formation of new species.

Why are models based on optimality often used to explain adaptation? What does the use of games theory add? Optimality models and game theory are two fairly interlinked ideas, each of which, or a combination of the two, may be used to explain why a species has adapted to perform the behaviours observed in the wild. An optimality model aims to discover which phenotype/behaviour from a set of these, known as strategies, is optimal in terms of individual fitness of an organism (Rice, 2012). In order

The resurrection of oceanic dispersal in historical biodiversity. by Alan de Queiroz. The distribution of many taxa that are separated by oceans can be explained by either vicariance or oceanic dispersal. At first oceanic dispersal was the explanation used for the distribution of taxa separated by oceans. Since the 1930s till the 1960s time oceanic dispersal was the most common explanation because there were many plausible dispersal mechanisms that would make oceanic dispersal possible. Support

Evolution is a very controversial topic among scientists and religious supporters who have very different perspectives about how the Earth has evolved from what it was then to what it is now. The theory that scientists find most factually correct is that current species were descents from the original species that date to prehistoric times. Over a long period of time they had acquired new characteristics and physical traits to help them adapt in their ever changing environments. To try and experience

case of such sorts of varieties is that of the sex. Then again, there are couple of illustrations that are not connected with the specific sex. One of the cases incorporate Cladocera which likewise indicates varieties fit as a fiddle and size. Thus, cichlid fishes create dental polymorphisms. The part of improvement and additionally hereditary coordination for the development of any creature is petulant. There are numerous speculation with fluctuating perspectives on it. One standard speculation expresses
