Do guppies need oxygen from an air pump?

Topic: I'm setting up a guppy tank and was wondering if I need an air pump for them? Do they need those oxygen bubbles? I see a lot of fish aquariums with these “aeration” devices setup. What does it do for the fish.. does it add oxygen? Is it a waste of time and money? read more

An air pump does more then add oxygen (which you don't have to worry about with only a few fish), it also help with the circulation in the tank and maintaining the water pH. You should check the temperature of the tanks at various locations to make sure that there is enough circulation. read more

Despite the stories of guppies surviving without air pumps, the average fish owner should ensure that a guppy tank is fitted with an appropriate pump. When living in a tank, guppies swim freely, excrete waste and use a lot of oxygen. An air pump helps force oxygen back into the water continuously, pushing tiny air bubbles into it. read more

The air pump doesn’t directly supply oxygen, but it stirs the water surface, making the oxygen exchange happen. If you have a filter with the output stream close to the surface, or with an output that breaks the water surface, an air pump is not needed. read more

Posted by Megan V: Having an air pump in your aquarium is a great idea. The bubbles that float to the surface create “surface agitation” and that is what creates oxygen for the fish. What a lot of people don’t know is that there are filters that run from air. read more

You don't need an air pump. The only thing the air pump is for, is to cause a disturbance at the surface so the water can be airrated. The filter should cause enough of a disturbance. read more
