facts about goldfish

Goldfish: goldfish (Carassius auratus) was one of the early fish to be domesticated, and is still one of the most commonly kept aquarium fish. A relatively small Member of the CARP family (which also includes the koi fish and fish crucian), the goldfish is a domesticated version of the fish gray/olive/brown native to East Asia (first domesticated in China) which was introduced to Europe in the late 17th century. A mutation that brings out the goldfish is also known from other cyprinid species, such as carp and tench.
facts about goldfish
The most common type of Goldfish:
The Comet, which has a body length of tail and thin. The Comet was developed in the United States.

Fantails, which is shaped like a fat egg. They have an anal and double caudal fins (they are the bottom of the tail and fins).

Veiltails have long flowing fins, and is very popular. Some of them have outstanding telescope eyes on each side of their head.

Shubunkins tail fin (tail fin thats), and come in a variety of colors. They are very popular for swimming.

Black Moor is a favorite of my mother. They are all black, has a telescope eyes, and veiltails. In Britain they breed them specifically for the competition.

Lionheads have surging growth in their head which looks like a lion's mane type. They do not have a dorsal fin (top), and a double tail fins. Oranda and Lionhead is a veiltail with dorsal fin.

Bubble-eye goldfish is one of the most bizarre. They have large pockets under the eyes that look like someone blowing their chewing gum and stuck it under their eyes. Like Lionheads, they do not have a dorsal fin and can't swim too well.

A goldfish can grow to a maximum length of 23 inches (59 cm) and a maximum weight of 9.9 pounds (4.5 kg), though this is rare; most individuals goldfish grow under half this size. In the optimal conditions, goldfish may live more than 20 years (the world record is 49 years); However, most household goldfish generally only live six to eight years.

History
During the Tang dynasty, it is popular to raise fish in ponds. As a result of a genetic mutation is dominant, one of these carp displayed  "gold " (actually yellowish orange) than silver color. People began to breed a variety of gold rather than silver variety, and began to display them in a small container. The fish is not stored permanently in the container, but will be kept in a larger body of water, such as ponds, and only for special occasions where guests are expected to be transferred to a small container of them.

A crucian carp carrying a mutation for yellow pigment substance of old. Some of the first goldfish may look like this. In 1162, Consort Song dynasty ordered the construction of a pond to collect a variety of red and gold fish. Currently, people outside the Royal family is prohibited to keep the CARP from a variety of gold (yellow), yellow being the colors of the royal. This is probably the reason why there are more Orange goldfish than yellow goldfish, though the latter are genetically easier to breed.

As time passed, more mutations occur, resulting in a new color variation, and testing varieties of Goldfish were developed. The first recorded occurrence of the other colors of the year 1276. The first occurrence of luxury goldfish tail was recorded in the Ming dynasty. Year 1502, goldfish were introduced to Japan, where the Ryukin and Tosakin varieties were developed.

In 1611, goldfish were introduced to Portugal and from there to other parts of Europe. CARP were first introduced to North America in 1874 and quickly became popular in the United States.

Types of pet goldfish
Selective breeding over the centuries has produced several color variations, some of them far from the  "golden " color of pet fish first. There are also different body shapes, configurations of fins and eyes. Some extreme version of a goldfish need to be kept in an aquarium they are far less powerful than varieties closer to  "wild ". However, some variations, such as the Shubunkin hardier. The main varieties are:

Common names: Black Moor, bubble eye, heavenly eyes, Comet, Fantail, Oranda, Lionhead, Pearlscale, Pompom, Ryukin, telescope eye, Shubunkin, Ranchu, Panda Moor, Veiltail

Classification of Chinese goldfish
In China, that maintains the goldfish goldfish are classified into 4 main types, which are not commonly used in the West.

Dragon eye-goldfish with extended, e.g. Black Moor, bubble eye, eye and telescopes
Egg-Goldfish without a dorsal fin. e.g. Lionhead (note that the bubble eye without a dorsal fin belongs to this group)
Wen-Goldfish with dorsal fin and tail. e.g., Veiltail ( "Wen " is also the name of the characteristic headgrowth on such strains as Oranda and Lionhead)
CE (possibly also called  "grass ")-Goldfish without anything fancy. This is the type that is typically used in Japan, especially for Carnival's "goldfish scoops ".
Jikin and Wakin-Goldfish with double tail, but with the Comet body shape.

Goldfish in ponds
Goldfish are popular pond fish, since they are small, inexpensive, colorful and very hardy. In the pool, they might even survive if brief periods of ice formed on the surface, as long as there is enough oxygen is left in the water and swimming is not frozen solid.

The common goldfish, London and Bristol shubunkins, Jikin, Wakin, Comet and sometimes fantail can be kept in outdoor all year in the climate and the subtropical. Moor, veiltail, oranda and lionhead are only safe in the summer.

Pond goldfish; Outdoor small to large good though the depth should be at least 80 cm (30 in) to avoid freezing. During the winter, goldfish will become sluggish, stop eating, and often stayed at the bottom of the tank. This is completely normal; they will become active again in the spring. The filter it is important to clean up the garbage and keep the pond clean. The plant is very important because they act as part of the filtration system, as well as a food source for fish. The next useful plants because they increase the oxygen levels in the water.

Compatible fish include rudd, tench, orfe and koi, but the latter will require special care. Ramshorn snails are very helpful with eating any algae that grows on the pond. It is very important to introduce fish that will consume excess goldfish eggs in the pond, such as orfe. Without some form of population control, goldfish Ponds can easily be Overstock. Koi also may be crossword mating to produce a new sterile fish.

Goldfish in aquaria
CARP is usually classified as a coldwater fish, and can live in an aquarium heater. Like most goldfish, goldfish produce large quantities of waste both in their feces and through their gills, releasing harmful chemicals into the water. This also happens because goldfish can't digest excess proteins, unlike most tropical fish. Heaps of waste to toxic levels can occur in a relatively short period of time, which is often the cause of sudden death of fish. Maybe the amount of surface area of the water, not the water volume, which determines how many goldfish can live in a container, because it determines how much oxygen diffuses and dissolves from the air to the surface of the water; one square foot surface area of water for every inch of Goldfish length (370 cm/cm). If the water is to be further aerated with a water pump, filter or fountain, goldfish more can be stored in the container.

Goldfish Aquarium; Goldfish coldwater fish may be, but this does not mean they can tolerate the flow temperature changes. The sudden shift in temperature that come at night, for example in an office building in which the CARP may be stored in the tank of a small office, it could kill them, especially in the winter. Instead, the temperature over 25 C can be very damaging to a goldfish (this is the main reason why they shouldn't be kept in tropical tank).

The popular image of a goldfish in a small Aquarium is timeless. Unfortunately, the risk of stunting, deoxygenation, ammonia nitrite poisoning due to a small environment means that this is hardly a House that is suitable for every type of fish, and some countries have banned the sale of a bowl type under animal rights the Act.

Reputation should be a goldfish dying quickly is often due to poor care amongst uninformed buyers looking for  "cheap's" pets. Age well-cared-for goldfish in captivity can extend more than 10 years.

Fancy goldfish are not likely to survive long in the wild as they are handicapped by their bright fin colors; However it is not beyond the bounds of possibility that such a fish, especially stronger varieties such as Shubunkin, could survive long enough to breed with wild cousins. Common and Comet goldfish can survive and even thrive, in a climate where a pond for them can be made. The introduction of wild goldfish can cause problems for native species. In three generations of the breed most goldfish spawn will have returned to their natural olive color. Since they are carp, goldfish are also capable of breeding with certain species of carp and creating hybrid species.

Research by Dr. Yoshiichi Matsui, a Professor of fish farming in Kinki University in Japan, shows that there are subtle differences that indicate that while crucian fish is goldfish ancestors, they have pretty distorted to be considered a separate species.

Eating
General grievous fishes most foodLike, opportunistic feeder goldfish and not stop eating of their own accord. When excess food is offered, they will produce more garbage and feces, partly due to incomplete digestion of protein. The fish are fed too can sometimes be recognized by feces trailing from their Cloaca. Goldfish need only be given food as much as they can consume in three to four minutes, and no more than twice a day. Indirek extreme can be fatal, usually by the explosion of the intestine. This happens most often with selectively bred goldfish, which have complicated intestinal tract compared with one straight in common carp. Novice Fishkeepers who have bought a new ruykin, fantail, oranda, lionhead or  "fancy another " goldfish will need to watch their fish carefully for a few days, because it's important to know how many goldfish will eat in a few minutes of time.

Special food Goldfish have a lower protein and carbohydrate content. It's sold in the present two-flakes that float on top of the Aquarium, and the pellets slowly sink to the bottom. Goldfish enthusiasts will supplement this diet with shelled peas (with the outer skin removed), blanched green leafy vegetables, and bloodworms. Young goldfish also benefit from the addition of brine shrimp to their diet.

The behavior of the
The behavior may vary both because goldfish are placed in various environments, and because their behavior can be conditioned by its owner. A common misconception that goldfish only have three seconds of memory has been proven false.

Scientific studies conducted on the matter have shown that Goldfish have strong associative learning abilities, as well as learning social skills. In addition, their strong visual acuity allows them to distinguish between the different human beings. It is highly likely that the owner will see the fish react favorably to them (swim to the front glass, swimming rapidly around the tank, and going to the surface mouthing for food) while hiding when other people approach the tank. Over time, goldfish should learn to associate their owners and other humans with food, often  "begging you" for food whenever their owners approach.

CARP is also showing a wide range of social behavior. When new fish are introduced to the tank, aggressive social behavior can sometimes be seen, such as the pursuit of a new fish, or fin nipping. This usually stops within a few days. Fish that have lived together often seen showing the behavior of the school, as well as showing the same kind of eating behavior. CARP can display similar behavior when responding to the reflection in the mirror.

Goldfish are a constant visual contact with man also seems to stop associating them as a threat. After being stored in the tank for a few weeks, it became possible to  "pet's" goldfish in the head, feed by hand, or even Cup a hand around it without reacting with a scary way. Some Goldfish have been trained to swim through mazes, push the ball through the hoop or even swim in a synchronized routine by the owner.

Goldfish have behaviors, as a group and as individuals that come from native carp behavior. They are a generalist species with diverse food, farm, and predator avoidance behaviors that contribute to their success in the environment. As the fish they can be described as  "friendly's" towards each other, very rarely will a goldfish harm another goldfish, or committed a crime men women during maintenance. Only the real threat that goldfish present each other is in the competition for food. Commons, comets and other faster varieties can easily eat all the food during feeding before fancy varieties can reach it. This could be a problem that leads to stunted growth or maybe starvation testing varieties when they are stored in a bond with their brothers and sisters in a single-tailed. As a result, when the mixing of lineages in the Aquarium environment, care should be taken to combine only offspring with similar body and swim characteristics.

Native environment
Goldfish Natively live in a pond, and other slow-moving or still body of water at depths up to 20 m (65 ft). Their original subtropical climate to tropical and they live in fresh water with a pH of 6.0 8.0, hardness 5.0 19.0 DJBM water and temperature ranges from 40 to 106 F (41 to 4 C) although they won't last long at a high temperature. They are considered not suitable even for living in a hot, tropical fish tank, because they are used to the amount of oxygen in cold water in the tank is bigger, and some people believe that the heat burned everything. However, Goldfish have been observed to live for centuries in an outdoor pond where the temperature often spikes above 86 F (30 C). When found in nature, a goldfish who really olive green color.

In the wild, the diet consists of crustaceans, insects, and plant matter. While it is true that goldfish can survive in a wide temperature range, the optimal range for the fish pond is 68 to 75 F (20 to 23 C). A pet goldfish, with many other fish, usually eat more food than is needed if given, which can cause fatal intestinal blockage. They are omnivorous and do your best with a variety of fresh vegetables and fruits to supplement a diet staple pellets or flakes.

Sudden change in temperature of the water can be fatal to fish, including goldfish. When transferring a store-bought goldfish for the pond or tank, the temperature in the storage container should be equalized by leaving in the destination container for at least 20 minutes before removing the carp. In addition, some temperature change just might be too great for even the hardy goldfish to adjust. For example, buying a goldfish in a store, where water might be 70 's F (approx 21 C), and hope to release it to Your Garden pond at 40 F (4 C) will likely result in the death of a goldfish, even if you use a slow immersion method just explained. Goldfish will need more time, perhaps a few days or weeks, to adjust the temperature as it is different.

Because goldfish like to eat live plants, their presence in the Aquarium can be quite a problem. Only a few aquarium plant species can survive in a tank with goldfish, for example the Cryptocoryne and Anubias species, but they do require special attention so that they are not uprooted. Fake plants that are often more durable, but the branches of the plant can often disrupt or harm fish if it comes in contact with them.

Breeding
Goldfish, like all cyprinids, lay eggs. They produce adhesive eggs that stick to the vegetation water. The eggs hatch in 48-72 hours, releasing FRY large enough to be described as appearing like eyelashes  "'s with two eyeballs ". In a week or so, the FRY starts to look more like a goldfish in shape, although it can take as much as a year before they develop a mature goldfish color; until then, they are a Brown metal as their wild ancestors. In the first week of their existence, FRY grow very fast-an adaptation born of the high risk of getting devoured by the adult goldfish (or fish and insects) in their environment.

Goldfish can only grow to sexual maturity if given enough water and proper nutrition. But if it continues to be good, they can breed indoors. Breeding usually occurs after significant changes in temperature, often in the spring. The eggs should then separated into another tank, like parents probably will eat one of their children that they happen upon. Dense plants such as Cabomba or Elodea or a spawning MOP used to catch the eggs.

Most goldfish can and will breed if left alone, especially in the setting of the pool. Males Chase females around, bumping and pushing them to solicit women to shed their eggs, which are then fertilize the female. Because of the odd shape of some extreme modern bred goldfish, certain types can no longer breed among themselves. In this case, a method of artificial breeding is used  "hand stripping called ". This method continues to proliferate case, but can be dangerous and harmful to fish if not done properly.

Mosquito control
Like some other popular aquarium fish, such as the guppy, goldfish and other gurame is often added to the body of stagnant water to reduce mosquito populations in some parts of the world, especially to prevent the spread of West Nile Virus, which relies on mosquitoes to migrate. However, the introduction of Goldfish often have negative consequences for the local ecosystem.

Edibility and cruelty
Although edible, goldfish are rarely eaten. Fashion among American College students for years was swallowing goldfish as a stunt and as an initiation for Fraternities. The first example was recorded in 1939 at Harvard University. The practice gradually fell out of popularity for decades and no longer hold.

Goldfish be scooped
In many countries, operators of Carnivals and exhibitions often give a goldfish in a plastic bag as a gift for winning the game. In the United Kingdom, the Government proposed banning this practice as part of the company's animal welfare Bill, though this has since been amended to only prevent goldfish being given as gifts to minors. However, in Rome, Italy, the city ratified the Statute at the end of 2005, which prohibits the use of Goldfish or other animals as Carnival prizes. Rome also has banned the keeping of goldfish in the  "goldfish bowls ", on the premise that it is cruel for the fish to live in small, confined spaces.

Humane killing of fish for human consumption or benign purposes (such as putting sick fish) is still legal in most countries (as long as the fish are not protected fish captured in the wild, protected fish reserves or in water where the person concerned has no right to collect the fish). In the United Kingdom, it is illegal to sell live fish (including CARP) as  "feeder fish " for the consumption of other animals.
