Yes, like all animals, goldfish need oxygen. They get it through their gills from the water they swim in .
Air should be provided to an aquarium via a small pump. This helps to remove gasses from the water that might build up and provides oxygen that will dissolve into the water. It also helps keep the tank clean.
yes they do
