Do Bettas Need Air Pumps?

Air pumps or air bubblers are a piece of equipment that many tanks have. However, a betta tank isn’t like other tanks, and you may be wondering “Do bettas need air pumps?”

Keep reading to have all your questions answered!

Spoiler alert bettas DON’T need air pumps. However, that doesn’t mean you shouldn’t have one in your tank!

What Do Air Pumps Do?

The main reason people have air pumps in their tanks isn’t for aesthetic purposes! In fact, air pumps are used to oxygenate the water. It does this by moving oxygenated water to the bottom of the tank, and pushing water from the bottom of the tank (which normally contains carbon dioxide) back to the top, oxygenating it!

However, don’t be mistaken. The bubbles passing through the water aren’t what oxygenate it. In fact, it’s the surface movement caused by the bubbles! When there’s a lot of surface movement, the gas exchange between your tank water and the air increases, causing your bettas water to become more oxygenated!

What’s The Difference Between An Aquarium Filter And An Air Pump?

You may notice that your filter agitates the water surface of your tank. But is there any difference?

Well, the biggest one is that your air bubbler isn’t going to clean your tank. When water goes through your filter, it passes through many different media including sponge, biological and chemical. Once it passes through all of these media (and in many cases more) it is clean again.

However, an air pump doesn’t have these media. Even though it’s moving water in the same way as a filter, it’s definitely not cleaning it! While your tank can do just fine without a bubbler, it certainly can’t without a filter.

Are Air Pumps Necessary For Betta Tanks?

Air pumps aren’t essential for betta tanks, and in general aren’t essential for any tank. If your filter is agitating the surface of the water enough, then that’s going to be enough for a high rate of gas exchange to occur.

On top of this, if your bettas water is shifting and moving too much, then they’re going to become stressed and agitated. So if you do plan on using an air pump, then you should go for one that is more gentle.

The main reason air pumps aren’t necessary for betta tanks is because of a bettas labyrinth organ. The labyrinth organ means that bettas don’t have to breathe through gills. Instead, they can go to the surface of the water to breathe oxygen as well.

However, there are times when an air pump can be beneficial.

When Should You Use An Air Pump

If your housing your betta with other fish or even by themselves, there are times when you should use an air pump for the safety of all your fish.

If You’re Using Medication

If your betta is sick and you’re using medication then you should use an air pump. A lot of medications remove oxygen from the tank as a side effect. So without an air pump, your betta will begin to suffocate.

And you’re probably thinking that if he has a labyrinth organ why does it matter?

In some cases, such as with swim bladder disease, your betta may not be able to swim to the surface of the water. So an air pump is essential.

As A Precaution

Another reason to get an air pump is as a precaution. If there’s a power cut in your area or your filter stops working then the water in your tank won’t be aerated. Buying a battery powered air pump will fix this problem. While you’ll still have to perform water changes more regularly until your filter is fixed, at least you won’t have to worry about your betta suffocating!

Do Bettas Like Air Pumps?

You don’t really need an air pump, but what does your betta think?

Just because they’re not necessary doesn’t mean your betta won’t like them. For example, a lot of bettas like to play with the bubbles that come out of an air pump. This form of entertainment will stop them being bored and can be used as a great toy.

However, on the other hand, bettas don’t like strong moving water. So if your air pump is disturbing the water too much it’s going to stress him out.

So Do Bettas Need Air Pumps?

There are a lot of great reasons for getting an air pump. You can use them in an emergency, for your quarantine tank and to keep your betta entertained! But even with all these reasons, it’s still not a piece of equipment your tank can’t go without.

Personally, I’d buy an air pump just because they’re so cheap, and if your betta doesn’t like it, at least you can use it in your quarantine tank.

But the choice is up to you, and with or without one your betta is going to be just fine!
