A fish tank bigger than the size of goldfish bowl needs a fish tank pump. The pump circulates water through a filter, and pumps air into the water to keep it oxygenated, so your fish can breathe.


You need a quality fish tank pump appropriate for the size of your aquarium. Usually, aquariums come with built-in pumps, but you may need to replace yours if it breaks down, or should you want one of higher quality.
