Do goldfish grow to size of tank?
Goldfish will not stop growing when properly cared for. indeterminate growers are what most fishes are known for. Poor water quality and a lack of proper care stunts a fish’s growth. Goldfish are not the only fish that will grow to a certain size, but they are by far the most common.
In fact, it is estimated that over 90% of all fish in the United States will reach adulthood by the time they reach the age of 5 years old. The reason for this is that most fish are born with a set of genes that determine their growth rate.
These genes are passed down from parent to offspring, and they determine the size of the fish as well as the amount of food they need to survive. For example, some fish have a genetic mutation that causes them to grow at a much faster rate than the rest of their species. When this happens, these fish can grow much larger than their normal size.

If you do not have access to a large freshwater tank, you may want to consider adding a small amount of aquarium salt to the aquarium. This will help to reduce the ammonia and nitrite levels in the water.
