trout pellets, they make the goldfish grow larger, faster, just a couple a day
Oscars eat goldfish. Therefore, does it really matter if Oscars are faster?
because your goldfish has a tomber(cancer)
no because, a baby goldfish takes 1 year to grow.
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 commonly grow to over 10 inches given proper care and conditions.
Yes, they will grow almost to half the size of their tank.

It doesn't !
Goldfish have the potential to grow very large if given the necessary amount of space from the very beginning. This means that if you put one goldfish in the recommended 20 gallons on it's own, it could potentially grow quite large.
Yes.
No it will not. It will be runted by the lack of room. In order for goldfish to grow to full size they should be housed in ponds or very large aquaria.
