How long do goldfish live to be?

Question

I have the little 10 cent goldfish, not the big kind. I also have one a little bit bigger that was $2 how long do these live to?

Answer 1

Goldfish can have lifespans up to 20+ years if they are fed a varied diet and housed in exceptional water conditions. They need to be in tanks that are not overcrowded. They need sufficient swimming room and do best if they are kept with their own types.
Although there is one report of a pet goldfish who lived 43 years, 25 years is a more reasonable maximum lifespan for a goldfish kept in a pond. In an aquarium, ten years is more likely. In the wild, lifespan is undoubtedly less.

Answer 2

With proper care, they can live over 20 years. Several have reached 40 or more. It's when they don't get proper care that they live for a year or two.

Your little 10 cent goldfish will become large enough in time - these are "commons" that can get 18" or longer. He'll be 2-3 inches within a year. Your other one might be a "fancy" variety (ones that have double tails) and these can get 8-10 inches (sometimes more). Hopefully you have a large tank with a filter and aren't trying to keep them in a bowl. You could keep both in a 10 gallon tank for a while, but by the time they're adults, you might need a 20-30 gallon tank (or larger). This also helps with keeping the water clean and dilutes the ammonia the fish produce so they aren't affected by ammonia poisoning.

Good luck with your fish. Some goldfish care and aquarium links for you:

Answer 3

There are comments of goldfish living as long as 30 years. usual goldfish stay plenty longer than the fancier varieties, in spite of the undeniable fact that many times, with the right foodstuff, living living house and care, 10-15 years is a sturdy existence span for a goldie. They maximum maximum probable die upfront provided that of inadequate care, room, or being further today into an uncycled tank. My present day goldfish are a veiltail/fantail mixture and a shubunkin. The shubunkin is 5, the mixture is merely about 10.....And seeing as I have been given him once I wasa first-time fish keeper at ideal 6, it somewhat is now no longer risky going!

I have 2 that are both 8 years old. Both were feeder fish (50 cents) and now both are the size of the ones they usually sel for $6.


And no, goldfish dont grow to be as big as what they are kept in.They can and often do get bigger then it.

The little 10 cent goldfish can grow up to be as big if not bigger then the other one.

Answer 5

Not very old, unless you take really good care of them. We had one growing up that was like 5 or 6 years old when he died. But my Mom took care of him.

FYI - Goldfish grow to the size of the container they are in. If you put your little goldfish in a bigger space, he will grow as big as he can to fit the space.

For those of you giving 'thumbs down' to my FYI, this little tidbit can be found on several goldfish websites.

"All fish give off pheromones, which limit their own growth in a closed environment, an adaptation that helps partition off limited natural resources in the wild."

Answer 6

well if there in a bowl about a week to two months unless you are lucky as they are very dirty fish in an aquarium with a proper filter and space easily five years or as long as ten.

Answer 7

not sure how long they live, but if you are putting them in the smae bowl the big one might eat the little one

Answer 8

If you take very good care of them, they might live a year or two.

Answer 9

if you take good care of them, they can last for about 4+ years

Answer 10

i heard they do 10000 knautical miles.
