Goldfish can live for many years if properly cared for, a bowl is not large enough. My goldfish lived 10 years in a 27 gallon tank but may have lived longer in a pond. 1 liter won't be enough - goldfish can grow to 10 inches long or even larger than that.
Koi, Shubunkins and most goldfish survive winter by remaining inactive. Do not feed your fish when water temperatures are below 39o F. (See Fish Care questions about changing the diet during colder months.) Use a pond de-icer to keep an area of the pond ice-free to allow for toxic gases to escape the pond.

Hi Mike, I have 150 gallon Rubbermaid stock tank pond on my patio with 3 mature(apx. 5-6 inches) and 5 young(1-1.5 inch) common goldfish. Earlier in the spring i noticed them showing spawning behavior and quickly made some DIY spawn mops. Unfortunately i missed them that morning and for whatever reason i never saw any fry as a result of that spawn. However, i left the mops in just in case because i had spotted a single egg, and i hoped there could be more.(or more to come) Then this week I saw them frolicking again and i checked the mops which are now LOADED with eggs. I am really excited but also concerned because I’ve read that goldfish are notorious for eating their young. Obviously with only 150 gallons of pond I cant care for them all if they all survived anyways so I’m okay with some losses as long as a few make it. Will some of the fry reach adulthood if everyone is left in the pond together? Or are my adult goldies going to tear it up like hungry orcas? Please advise. There is no right answer that will apply to every koi pond and water garden

Installing an outdoor goldfish pond is an entertaining and exciting way to add color and vibrancy to your backyard living area and garden. As a matter of fact, outdoor goldfish ponds have been a staple of Asian culture for centuries. Goldfish are distant cousins to the wild carp and are well suited to outdoor living, as they acclimate well to both warm and colder climates. In most areas of the United States, goldfish can even be left in the pond overwinter as long as holes are cut into the surface ice to facilitate proper gas exchange.Centuries of selective breeding have produced dozens of varieties of goldfish. However, this process has left some varieties of goldfish less hardy than their wild carp ancestors. Different experts have different recommendations for which types of goldfish can survive over winter, which usually means that different experts have had different experiences. The common goldfish and comet goldfish are almost universally acknowledged as handling outdoor ponds better than other species. If you have your heart set on a fancy goldfish, ryukins, shubukins and ranchus tend to tolerate pond conditions better than most.Comets will generally eat anything, but they do have specific nutritional needs. Commercial fish flake and pellets work well for comets. However, make sure that these preparations are intended for goldfish; goldfish need more carbohydrates than tropical fish. Additionally, the occasional vegetable, like peas or cooked carrots can help make sure a goldfish gets all the nutrients it needs. In an unheated, outdoor pond you should stop feeding for the winter once temperatures drop to the low fifties, since goldfish cannot digest as well at low temperatures.Ponds containing may also be suitable for goldfish, but it is important to remember that the care requirements of koi are rather different to that of goldfish, so ensure that both species can be properly cared for in the same pond.
