Yes, they can live in small ponds.
As feral fish yes, but they are not native to any wild waterways as they are an ornamental, man made, fish species. They were bred from bronze-coloured wild Carassius species of carp (you can still see this bronzing in some "reverted" Goldfish, specifically black ones which go bronze as they get older).
The previous answer mentioned size. Common/Comet (long-bodied) Goldfish are all genetically programmed to get around 10"-12" in length excluding fins. They are strictly pond fish. The shorter bodied Fancy Goldfish get between 5"-10" in body length excluding fins. Fancies need at least 20 US gallons (75 litres) per fish, Commons at least 40 US gallons (150 litres) per fish, preferably more. In ponds the pond must be over 600 US gallons (2,270 litres).
Assuming that the conditions of both the tank and wild are survivable, goldfish will tend to survive longer outdoors. Goldfish in general are quite durable, so living outside alone isn't an issue. In the wild, they aren't affected by the growth restrictions that tanks often cause. Goldfish also don't have very many natural predators in most places, so they can become both huge and numerous. In fact, goldfish and koi populations in some places have exploded so much that they threaten native species and disrupt entire ecosystems.
Yes! They are often found in ponds or lakes, mostly koi. They can get really big! They are related to carp, so they are really hardy.
Well, um, goldfish live in water. They are coldwater, and do not live in saltwater. They need at least a 10 gallon tank for each goldfish.
no, goldfish don't live in the ocean because they are fresh water fish, they originate from Asia but only live in fresh water.
no, but i DON'T know were they do live.
10+ years but they will need a very large tank.
No, goldfish are freshwater fish. Any goldfish you buy in the store are tank bred and not wild caught.
Goldfish in the wild are thought to live around 40 years. They live around 30 years when held in captivity.
Wild Goldfish are found in the Yangtze river, but are very different from the domesticated goldfish. In the wild, goldfish can grow up to five feet long, and are reputed to live for hundreds of years.
Fancy goldfish (the ones with a rounder body and double tail) live for around 5-10 years depending on breeding and water quality. Common goldfish (with the more streamlined body and single tail) can live for around 20 years. Goldfish very rarely reach this age because people keep them in tanks and bowls that are too small. It is a myth that they grow to the size of their tank, this causes stunting which shortens their life-span considerably.Well cared for, and in the right tank size, the life span of a goldfish can be 20+ years
they will live longer in both but mostly in the wild because it's their habitat and is where they suppose to be anyways
they live longer both ways
Some goldfish I guess. It depends on if it is wild or not.
some live in the wild around in USA but there mostly found in China.In China there found around in lakes,ponds,and sloughs.
Sea Lions live longer in captivity. An average life span for a sea lion in the wild is 18 years and 23 in captivity. But, that does not mean an animal in the wild can't live longer than one in captivity.
Perhaps it is sick. Perhaps it is because it is a wild animal and NOT a pet.
When they mate a few days after they will eggs. They tend to do this when it is about 70 degrees in the tank as it simulates spring when they would lay eggs in the wild.
