It can't be done. Goldies get huge unless they are the facy kind. Try a pond or get five in a thirty gallon.

No!!! You can keep a maximum of 2 goldfish in that tank. I know they seem small now, but they grow up to be 6 inches long!

Can an oranda goldfish live in same tank with regular goldfish?

Yes, but your tank size needs to support it. If you mean that a regular goldfish is a long single-tail goldfish, then you need at least a 40 gallon tank just for the 2 fish due to the size potential of the common goldfish. If you mean a regular goldfish as in a round bodied fantail, or perhaps a ryukin, then you need at least a 30 gallon tank for the 2 fish.


How does a goldfish grow as a size of a foot when in seawater and still the same size when in a bowl?

Goldfish release growth-inhibiting hormones into the water they live in: the more goldfish in a smaller space, the less likely they are to grow. For instance, if I have a common goldfish in a 5 gallon tank, it will grow to about the same size if I had 6 of the same fish in a 30 gallon tank. But leave that fish alone in a 30 gallon tank, and it will grow larger. This is why pond goldfish grow bigger. But goldfish won't grow at all in seawater; they aren't saltwater fish.

Goldfish grow extremely large; fancies will become fatter, and singletails grow quite long. You should only have 2 fancies in a 30 gallon, or one singletail for proper health and growth.
