A fancy goldfish needs 20 gallons on it's own, plus 10 gallons each per additional fish (2 goldfish for 30 gallons, 3 in 40 gallons etc).
Fancy goldfish can grow quite large, and they are very high waste producers; anything less can shorten their lifespan and cause them harm from the toxins in the water.
an average goldfish needs 7 or 8 litres.But mine can live in 4 liters but there was 2 but 1 died .so dont buy the gold and white ones. because my sister had one the same and he died too
If you use an old rule of thumb guide you will not go far wrong, that is :- 1 inch of fish to 1 gal of water. That's 10 off 5inch fish or any way you like to permutate it.
The size of the tank matters. You multiply the length by the width by the depth in cms then divide by 1000. And that's how much liters you will need. :D
You cannot put any goldfish in a 2 gallon tank.One fancy goldfish needs at minimum a 20 gallon tank on it's own. This is not just because of their adult size potential, but also because they are very messy fish and produce a high amount of waste.
You may want to add a liner to be on the safe side, but you could have 2 fancy goldfish, one one common or single tailed goldfish. (goldfish grow big and fast)
Since an oranda is classified as a fancy variety, you can put 4 Orandas on a 55 gallon tank.
If it is goldfish: 7 can fit. if it is mos other fish (besides koi) you can fit 14
I would personally say none, not for their entire lives anyway. You may get away with 2 Fancy Goldfish juveniles for a couple of months, but really Fancy Goldfish need a minimum of 20 gallons each and Common/Comet Goldfish a minimum of 55 gallons each for their entire lives! They get very big, are very messy and need a lot of water volume!
If they are fancy goldfish (the plump looking ones) then 6 or so would do well in an 80 gallon when fully grown if they are common goldfish, then 2 maybe 3 when full grown would be ok as they reach a whole foot long! This may seem like its not many fish for a large tank however goldfish are real poo machines and good filtration is a must.
it lays about 10,000 eggs at once
Two: There's commons and comets (Comets have longer fins). These are generally excluded from the "fancy" category. If you see a sign in your pet store labelling a non-fancy goldfish as "shubunkin", that's just the coloration. It's either a common goldfish, or a comet-tailed one.
It depends how big your bowl is if it is below 5 gallons then you should put one. But if it is 1 or 2 gallons then you will have to move it into a 5 gallon tank or bowl at the least.
7....But you should keep an good watch on them.
20 gallons for one fish and 10 gallon for each addition goldfish. See the related link for further information.
None. Goldfish should have a minimum of ten gallons of water per fish if you wish for them to live out their full lifespan of ~20 years.
