Biggest Goldfish?

Godmadefish

So how many gallons would you suggest for say a standard 6 inch fantail golfish?

Spooki

The standard recommendation is 20 gallons for 1 Goldfish and 10-20 gallons for every Goldfish after that. However, you have to make sure the length of the narrowest sides will be long enough for your Goldfish to turn around in. You can never say for certain that the cute little fish you buy is going to stop growing at 6 inches.

maybe the reason they got confused is because both are from the carp family but the Koi came from japan and Goldfish from china.
Goldfish are a easy to care for and come in over 120 varieties. Although rare, they have been known to grow to a maximum length of 23 inches and a maximum weight of 9.9 pounds. Most don't get larger than 10 to 12 inches. While the longest a Goldfish has ever lived is 40 years, most don't last longer than 6 to 8.

slightly off topic, but can you eat Goldfish? Like Goldfish sashimi...?

Spooki

I'm sure you could if you wanted to, so long as it hasn't been exposed to toxins. I know you're not supposed to eat fish exposed to malachite green, a common medication ingredient.

Okay... I hope I can breed a fish of that size. But I am still convinced that it is true.

I have seen common carp x Goldfish hybrids before, they're huge and often quite pretty. http://bankfisher.com/hybridgallery.JPG Although, i'm sure most of the hybrid offspring are probably ugly/deformed. If you want a really big "Goldfish" just go for Koi or carp instead.

Thank you. But Koi belongs to Goldfish family, right? pls correct me if i'm wrong.

Koi, carp and Goldfish are all related and are members of the "carp family". The scientific classification family they are all a member of is Cyprinidae. Cyprinidae is home to barbs, minnows, rasboras and sharks as well.

Koi- Cyprinus carpio
Goldfish- Carassius Auratus
Crucian carp- Carassius carassius
Common carp- Cyprinus carpio
Prussian carp- Carassius gibelio

You'll notice Koi and common carp have the same scientific name, they are the same species but look virtually nothing alike... much like how an oranda Goldfish llooks nothing at all like a comet Goldfish yet they are the same species. Koi are just domesticated ornamental carp. Goldfish and the common carp are closely related enough that they can produce viable offspring like horses and donkeys can produce a mule or hinny.

my friend say that this is true and this is a kind of Goldfish. Should I believe?
