This linguistic confusion is why Americans call the Pennsylvania Dutch Dutch even though they're Germans. To review: this country is the Netherlands, its people are Dutch, they speak Dutch. There is no country called Holland, but there are provinces of North and South Holland.
In clean, uncrowded conditions in tanks or ponds, goldfish grow fast. They can grow to a few inches (1 to 4 inches) within the first year. It really depends on their genetics and living situation. It may take a year or two before they change color from brown to gold or whatever color their parents were.
âFeed fish as much as much as they can consume in a 2-3 minute period several times daily.â Or thisâ¦ âFeed no more than your fish will consume in 5 minutes twice a day.â #facepalm. Those instructions will take your goldfish to bad health faster than a greased pig on roller skates in the average aquarium.
