Once your betta tank is setup, one of the next things you start to wonder is whether or not your betta needs an air pump.

Typically, bettas don’t need an air pump since they have a labyrinth that allows them to breathe air from the water surface. However, having a gentle air pump to maintain the proper oxygen concentration in the tank is recommended.

An air pump bubbles air through your tank and helps to maintain adequate oxygen concentration.

So a gentle air pump is not going to do any kind of harm to your betta.

In one of our home betta tank, we have an air pump setup that is connected with the sponge filter. And our betta is fine in that setup.

Generally, betta fish don’t prefer very fast flowing water. They thrive well in a tank that has gentle and calm water current – and a sponge filter just helps in providing such environment.

Air pumps are connected to air stones that produce beautiful bubbles. Now your betta might have fun playing with bubbles and moving around them.

Do Bettas Like Air Pumps?

Bettas don’t like fast-flowing waters. So if an air stone that is connected to the air pump creates a lot of bubbles and disturbance in the tank then the betta might not like it. However, some bettas may also enjoy playing with bubbles, so choosing the right setup is important.

In the wild, bettas generally live in standing water, in places like rice paddies, floodplains, or canals.

Although some of the bettas may like to play with bubbles and can be a great entertainment tool for your betta.

But fast-flowing bubbles that generate a lot of disturbance in the water might not be helpful and may even lead your betta to stress.

So just choose an air pump setup that generates gentle flow and circulation in the tank.

Sponge filter is beneficial for fish species such as betta which do not thrive in strong currents.
