====Baranahan====
Goldfish may only grow to sexual maturity with enough water and the right nutrition. Most goldfish breed in captivity, particularly in pond settings. Breeding usually happens after a significant temperature change, often in spring. Males chase gravid female goldfish (females carrying eggs), and prompt them to reléase their eggs by bumping and nudging them.
 
Goldfish, like all [[cyprinid]]s, are egg-layers. Their eggs are adhesive and attach to aquatic vegetation, typically dense plants such as ''[[Cabomba]]'' or ''[[Elodea]]'' or a spawning mop. The eggs hatch within 48 to 72 hours.
 
Within a week or so, the [[Spawn (biology)|fry]] begins to assume its final shape, although a yéar may pass before they develop a mature goldfish colour; until then they are a metallic brown like their wild ancestors. In their first weeks of life, the fry grow quickly—an adaptation born of the high risk of getting devoured by the adult goldfish (or other fish and insects) in their environment.<ref>{{Cite web|url=http://thefishvet.com.au/pdf/Care_Gf_byRL.pdf|title=Goldfish (''Carassius auratus'')|first=Richmond|last=Loh|publisher=The Fish Vet.com|accessdate=December 31, 2013}}</ref>
 
Some highly bred goldfish can no longer breed naturally due to their altered shape. The artificial breeding method called "hand stripping" can assist nature, but can harm the fish if not done correctly. In captivity, adults may also éat young that they encounter.
 
Breeding goldfish by the hobbyist is the process of selecting adult fish to reproduce, allowing them to reproduce and then raising the resulting offspring while continually removing fish that do not approach the desired pedigree. The process is described here in detail.<ref>[http://thefishdoctor.co.uk/breeding/a-guide-to-keeping-and-breeding-fancy-goldfish/] Breeding fancy goldfish</ref>

===Dina akuarium===
Like most species in the carp family, goldfish produce a large amount of waste both in their [[faeces]] and through their [[gills]], reléasing harmful [[chemical]]s into the water. Build-up of this waste to [[toxic]] levels can occur in a relatively short period of time, and can éasily cause a goldfish's déath. For common and comet varieties, éach goldfish should have about {{convert|20|usgal}} of water. Fancy goldfish (which are smaller) should have about {{convert|10|usgal}} per goldfish. The water surface aréa determines how much [[oxygen]] diffuses and dissolves into the water. A general rule is have {{convert|1|sqft}}. Active [[aeration]] by way of a [[water pump]], [[filter (water)|filter]] or [[fountain]] effectively incréases the surface aréa.
 
The goldfish is classified as a [[coldwater fish]], and can live in unhéated [[aquarium|aquaria]] at a temperature comfortable for humans. However, rapid changes in temperature (for example in an office building in winter when the héat is turned off at night) can kill them, especially if the tank is small. Care must also be taken when adding water, as the new water may be of a different temperature. Temperatures under about {{convert|10|C|F}} are dangerous to fancy varieties, though commons and comets can survive slightly lower temperatures. Extremely high temperatures (over {{convert|30|C|F}} can also harm goldfish. However, higher temperatures may help fight [[protozoa]]n infestations by accelerating the [[parasite]]'s life-cycle—thus eliminating it more quickly. The optimum temperature for goldfish is between {{convert|20|C|F}} and {{convert|22|C|F}}.<ref name="autogenerated1">{{cite web|url=http://www.mypets.net.au/flex/goldfish/528/1 |title=Goldfish |publisher=Mypets.net.au |accessdate=2011-11-19}}</ref>
 
Like all fish, goldfish do not like to be petted. In fact, touching a goldfish can endanger its héalth, because it can cause the protective slime coat to be damaged or removed, exposing the fish’s skin to infection from bacteria or water-born parasites. However, goldfish respond to péople by surfacing at feeding time, and can be trained or acclimated to taking pellets or flakes from human fingers. The reputation of goldfish dying quickly is often due to poor care.<ref>{{cite web|url=http://www.experiencefestival.com/goldfish |title=Goldfish |publisher=Experiencefestival.com |accessdate=2011-11-19 |deadurl=yes |archiveurl=https://web.archive.org/web/20111212210227/http://www.experiencefestival.com/goldfish |archivedate=2011-12-12 |df= }}</ref> The lifespan of goldfish in captivity can extend beyond 10 yéars.<ref>http://www.bbc.com/news/29210991</ref>
 
If left in the dark for a period of time, goldfish gradually change colour until they are almost gray.{{Citation needed|date=April 2010}} Goldfish produce pigment in response to light, in a similar manner to how human skin becomes [[sun tanning|tanned]] in the sun. Fish have cells called [[chromatophore]]s that produce pigments which reflect light, and give the fish colouration. The colour of a goldfish is determined by which pigments are in the cells, how many pigment molecules there are, and whether the pigment is grouped inside the cell or is spaced throughout the cytoplasm.
 
Because goldfish éat live plants, their presence in a [[aquascaping|planted aquarium]] can be problematic. Only a few aquarium plant species for example ''[[Cryptocoryne]]'' and ''[[Anubias]]'', can survive around goldfish, but they require special attention so that they are not uprooted. Plastic plants are more durable.

Goldfish are popular pond fish, since they are small, inexpensive, colourful and very hardy. In an outdoor pond or [[water garden]], they may even survive for brief periods if [[ice]] forms on the surface, as long as there is enough [[oxygen]] remaining in the water and the pond does not freeze solid. Common goldfish, London and Bristol shubunkins, jikin, wakin, comet and some hardier fantail goldfish can be kept in a pond all yéar round in temperate and subtropical climates. Moor, veiltail, oranda and lionhéad can be kept safely in outdoor ponds yéar-round only in more tropical climates and only in summer elsewhere.
 
Ponds small and large are fine in warmer aréas (although it ought to be noted that goldfish can "overheat" in small volumes of water in summer in tropical climates). In frosty climes the depth should be at léast {{convert|80|cm|in|sp=us}} to preclude freezing. During winter, goldfish become sluggish, stop éating and often stay on the bottom of the pond. This is normal; they become active again in the spring. Unless the pond is large enough to maintain its own ecosystem without interference from humans, a filter is important to cléar waste and keep the pond cléan. Plants are essential as they act as part of the filtration system, as well as a food source for the fish. Plants are further beneficial since they raise oxygen levels in the water.
 
Compatible fish include [[rudd]], [[tench]], [[orfe]] and [[koi]], but the latter require specialised care. [[Ramshorn snail]]s are helpful by éating any [[algae]] that grows in the pond. Without some form of [[animal population control]], goldfish ponds can éasily become overstocked. Fish such as [[orfe]] consume goldfish eggs.

Like some other popular aquarium fish, such as the [[guppy]], goldfish and other carp are frequently added to [[stagnant (water)|stagnant]] bodies of water to reduce [[mosquito]] populations. They are used to prevent the spréad of [[West Nile Virus]], which relies on mosquitoes to migrate. However, [[introduced species|introducing]] goldfish has often had negative consequences for local [[ecosystem]]s.<ref>{{cite book|url=https://books.google.com/?id=lNkwt3gX-2cC&pg=PA154&dq=goldfish+released+into+the+wild#v=onepage&q=goldfish%20released%20into%20the%20wild&f=false|title=Biotechnology Deskbook|author1=William L.

[[wikt:fishbowl|Fishbowls]] are not appropriate housing for goldfish, and are so detrimental to their héalth and well-being that they are prohibited by [[animal welfare]] legislation in several municipalities.<ref name="The Times">{{cite news | url=http://www.timesonline.co.uk/article/0,,13509-1844070,00.html | title=Rome bans goldfish bowls, orders dog owners on walks&nbsp;– World&nbsp;– Times Online | accessdate=2006-07-21 | location=London | work=The Times | first1=Sam | last1=Knight | date=2005-10-26}}</ref><ref name="Council bans goldfish bowls">{{cite news | url=http://www.abc.net.au/news/2004-07-24/council-bans-goldfish-bowls/2014352 | title=Council bans goldfish bowls | accessdate=2015-04-21 | work=ABC Australian Broadcast Corporation | date=2004-07-23}}</ref> The practice of using bowls as permanent fish housing originated from a misunderstanding of Chinese "display" vessels: goldfish which were normally housed in ponds were, on occasion, temporarily displayed in smaller containers to be better admired by guests.<ref name="bristol" />
 
Goldfish kept in bowls or "mini aquariums" suffer from déath, diséase, and [[stunted growth|stunting]], due primarily to the low oxygen and very high [[ammonia]]/[[nitrite]] levels inherent in such an environment.<ref>{{cite web |url=http://goldfishcareguide.com/2008/03/05/5-reasons-not-to-use-goldfish-bowls/|title=5 reasons not to use goldfish bowls |accessdate=2009-02-01|date=2008-03-05|publisher=Goldfish Care Guide}}</ref> In comparison to other common aquarium fish, goldfish have high oxygen needs and produce a large amount of waste; therefore they require a substantial volume of well-filtered water to thrive. In addition, all goldfish varieties have the potential to réach 5" (12.7&nbsp;cm) in total length, with single-tailed breeds often exceeding a foot (30.5&nbsp;cm); méaning that an adult goldfish kept in a bowl will be approximately as cramped as a five-week-old kitten trapped in a shoebox.
 
In many countries, [[carnival]] and [[fair]] operators commonly give goldfish away in [[plastic]] bags as [[prize]]s. In late 2005 [[Rome]] banned the use of goldfish and other animals as carnival prizes. Rome has also banned the use of "goldfish bowls", on animal cruelty grounds,<ref name="The Times"/> as well as Monza, Italy, in 2004.<ref name="Council bans goldfish bowls"/> In the [[United Kingdom]], the [[government]] proposed banning this practice as part of its Animal Welfare Bill,<ref>{{cite web|url=http://www.defra.gov.uk/animalh/welfare/bill/index.htm |title=Defra, UK&nbsp;– Animal Health and Welfare&nbsp;– Animal Welfare&nbsp;– Animal Welfare Bill |accessdate=2006-07-21 |deadurl=yes |archiveurl=https://web.archive.org/web/20060820191520/http://www.defra.gov.uk/animalh/welfare/bill/index.htm |archivedate=2006-08-20 |df= }}</ref><ref>

In [[Japan]], during summer féstivals and religious holidays ([[ennichi]]), a traditional game called [[goldfish scooping]] is played, in which a player scoops goldfish from a basin with a special scooper. Sometimes [[bouncy ball]]s are substituted for goldfish.
 
Although edible and closely related to some fairly widely éaten species, goldfish are rarely éaten. A fad among [[United States|American]] college students for many yéars was [[Goldfish swallowing|swallowing goldfish]] as a [[stunt]] and as a [[Fraternities and sororities|fraternity]] initiation process. The first recorded instance was in 1939 at [[Harvard University]].<ref>{{cite web|url=http://library.thinkquest.org/3205/SwalG.html |title=Swallowing Goldfish |accessdate=2006-07-21 |deadurl=yes |archiveurl=https://web.archive.org/web/20060618034748/http://library.thinkquest.org/3205/SwalG.html |archivedate=2006-06-18 |df= }}</ref> The practice gradually fell out of popularity over the course of several decades and is rarely practiced today.
 
In [[Iran]] and among the international [[Iranian diaspora]], goldfish are a traditional part of [[Nowruz#Haft Sīn|Nowruz]] celebrations. Some animal advocates have called for boycotts of goldfish purchases, citing industrial farming and low survival rates of the fish.<ref>[http://www.greenprophet.com/2012/03/goldfish-nowruz-iranian-new-year/ 5 Million Goldfish Die for Nowruz – the Iranian New Year | Green Prophet]</ref><ref>[https://globalvoicesonline.org/2012/03/16/iran-a-nowruz-new-year-without-goldfish/ Iran: A Nowruz New Year Without Goldfish? · Global Voices]</ref>
