how big size can grow goldfish upto?

Answer 1

Gold fishes basically need lot of swimming space and also water volume to dilute the nitrates and nitrites since they generate lot more waste compared to other tropical varieties. Some of the common varieties can reach the size of 12 inches or so and for such varieties the 10G rule does not apply. The 10G rule applies to fully grown fancy varieties such as Lion head, Oranda etc.. Smaller fishes can be stocked a bit more but they usually grow very fast and need to be shifted to bigger tanks or other tanks to reduce the population. Common gold fish, Comet and Shubunkin are larger fishes and can reach easily 6 to 12 inches depending on the variety. They do better in an outdoor pond where they can have larger swimming space.

Answer 2

Your typical goldfish can grow up to a foot long, and there have even been reports of much larger fish.

Most people don't realize that a goldfish can easily live 20-30 years if properly cared for.

Answer 3

For fancy, globoid-bodied goldfish, a seven to eight inch (20cm) body length is very large. Most top out at five to six inches. Wild-type fish like Comets and Shubunkins can get larger: body lengths over one foot (30cm) are not uncommon. I saw a common goldfish caught from a lake that I swear (I didn't catch it, so I have some credibility here....) must have been close to eighteen inches in length.

Answer 4

depending on the type of goldfish-some, if given a large amount of water to live can get very large. The common feeder goldfish is actually a carp and have been known to get over 5 pounds and over 2' long

Answer 5

Even fancies can get pretty large, here is link to an article about Bruce the giant goldfish

Most don't get that big but if taken care of properly and given enough space they can get around 8-12 inches. Single tailed goldfish can grow even bigger up to 12-18 inches but these should really be kept in ponds.

Answer 6

Dear Emily
Comets ( common goldfish) can get to over a foot, where your fancier gold fish ( like orandas,ryukans,fantails etc) can get around 6 to 8 inches. Kio ( these are carp not goldfish) can get up to 3 feet.

Answer 7

goldfish can really grow to a very large size I once had one to grow to a very large size and I had a fifty gallon tank everybody use to tell me that I gave that fish something to make it that big,but I did nothing special to make it grow that big.
