    Do Betta fish need a bubbler and air pump? This is a question that many people have and the answer is not always clear.

    In most cases, Betta fish don’t need a bubbler and air pump. Betta fish are very adept at getting oxygen from the surface of the water, so a bubbler is not necessary for them to get oxygen. However, there are some instances where a bubbler may be helpful.

    In this article, we will take a look at what bubblers are, what they do, and whether or not Bettas need them. We will also discuss some of the pros and cons of using a bubbler in your tank. So, if you are curious about whether or not your Betta needs a bubbler, read on!

    Do Betta Fish Need A Bubbler And Air Pump In Their Tank?

    do bettas like air stones

    Betta fish, also known as Siamese fighting fish, are a type of freshwater fish that originates from Southeast Asia.

    Bettas are labyrinth fish, which means they have a specially adapted organ that allows them to breathe air directly from the surface.

    This means that they technically don’t need a bubbler or air pump in their tank, as they can get all the oxygen they need from the surface of the water.

    However, there are some benefits to using this equipment in a Betta tank, so it’s still worth considering.

    Your Betta tank needs a bubbler and air pump if:

    • You have a large tank
    • The water gets dirty fast
    • Your Betta has tank mates
    • The water isn’t well-oxygenated
    • There are no live plants in the tank

    Your Betta tank doesn’t need a bubbler and air pump if:

    • You have a small tank
    • Your Betta lives alone
    • You already have a filter
    • The water is clean and well-oxygenated
    • There are live plants in the tank that provide oxygen

    How Does A Bubbler / Air Pump Work?

    A bubbler is a piece of equipment that pumps air into the water. There are many types of bubblers available on the market right now, such as bubble wands, bubble ornaments, and bubble walls. One of the most popular types is the air stone because it’s small, safe, easy to use, and easy to include in your tank setup.

    Bubblers are connected to an air pump in order to work. As the pump draws air in, it forms bubbles in the water.

    These bubbles float up to the surface, breaking the surface tension of the water and allowing oxygen to be dissolved into the water. This process is known as aeration and it’s very important for the health of your fish.

    Aeration helps circulate the water in your tank, which is important for the overall health of your ecosystem. It also provides your Betta with a source of oxygen, which can be helpful if the tank isn’t well-oxygenated.

    As mentioned above, bubblers come in all shapes and sizes, so you’re sure to find one that is suitable for your tank.

    Benefits Of Using A Bubbler In A Betta Fish Tank

    There are many advantages to using a bubbler and air pump in your Betta tank. Let’s take a look at some of the benefits here.

    Oxygenates The Water

    One of the main benefits of using a bubbler and air pump is that they oxygenate the water and promotes better gas exchange.

    This is the process by which oxygen is dissolved into the water and carbon dioxide is released into the air. This is especially important if you have a large tank or if the water isn’t properly oxygenated.

    Adds Movement

    Another benefit of using bubblers and air pumps is that they add surface movement Betta tanks. This is helpful in preventing stagnant water, which leads to the growth of harmful bacteria.

    Have you ever seen that slimy-looking film that covers the surface of stagnant water? That’s called a biofilm, and it’s made up of bacteria, algae, and other microorganisms. These organisms can be harmful to your fish, so it’s important to avoid stagnant water.

    Stagnant water can lead to the growth of harmful bacteria, so it’s important to keep the water moving.

    Circulates The Water

    Since air bubblers create movement, they also help with water circulation.

    You can even attach your air pump to a sponge filter or a box filter to better help with this. As the aquarium bubbler pushes the air into the water, it also pulls water through the filter, which cleans it and removes waste that may be in it.

    This is a great way to keep your water clean and your fish healthy. It’s especially important in larger tanks where water quality can deteriorate quickly.

    Entertains Your Fish

    Last but not the least, bubblers can provide entertainment for your fish. Betta fish are known to be curious creatures, so they may enjoy watching the air bubbles floating around in their tank. Some Bettas even enjoy riding the bubbles and chasing them around.

    How To Oxygenate A Betta Tank Without A Bubbler Or Air Pump

    If you don’t have a bubbler or an air pump, there are still ways that you can oxygenate your Betta tanks. We actually talked about this previously in previous blog post, but we’ll cover the basics here. If you need more detailed information, simply refer to that blog post.

    Use Live Plants

    One of the best ways to oxygenate your tank is to use live plants. Plants produce oxygen as a by-product of photosynthesis, so they can help increase the amount of dissolved oxygen in your water.

    Not only do they provide a source of oxygen, but they also help keep your water clean and clear. They absorb nutrients from the water that would otherwise lead to algae growth.

    Change The Water Regularly

    Another way to ensure that your Betta has enough dissolved oxygen is to clean the tank and change the water regularly. When you do a water change, you’re essentially adding fresh, oxygen-rich water to the tank.

    This is especially important if you have a small tank or if your fish produces a lot of waste. A good rule of thumb is to do a water change every week, but you may need to do it more often if your tank is on the smaller side.

    Use A Wider But Shallower Tank

    Obviously, this doesn’t apply if you already have your tank, but one way to get away with not having a bubbler or air pump in your aquarium is if you didn’t need it in the first place.

    A larger surface area means more oxygen exchange. That’s why it’s generally recommended that you use a wider but shallower tank for labyrinth organ fishes, such as Bettas. Remember, labyrinth fishes need to frequently surface to breathe air, so a wider but shallower tank will allow them to do this better.

    After all, not only will it give your labyrinth breather more room to swim, but it will also help ensure that there’s enough dissolved oxygen in the water.

    How To Tell If A Fish Tank Doesn’t Have Enough Oxygen

    should I use an air pump with a betta

    If you’re not sure if your tank has enough oxygen, there are a few signs to look for.

    • Your fish are gasping at the water’s surface: This is a sure sign that your fish are not getting enough oxygen from the tank water. If they’re spending more time at the surface, it’s because they’re trying to get breathe gaseous air to absorb oxygen.
    • Your fish are gulping air. Gulping air is different from gasping. When a fish gulps air, they open its mouth and take a quick breath in. They usually do this when they’re feeling stressed or if the water has a low oxygen level.
    • Your fish are listless and lethargic: If your fish are listless and uninterested in their surroundings, it could be a sign that they’re not getting enough oxygen.
    • Your fish are gathered around the bubbler: If you have a bubbler in your tank, you may notice that your fish are gathered around it. This is because they’re trying to get as much oxygen from the bubbles as possible.
    • Your fish are dying: This is the most extreme and serious sign that your tank is lacking oxygen. If you’re noticing a high mortality rate, it’s time to take action.

    Can Bettas Live Without A Bubbler?

    Bubblers are a great way to oxygenate your water and keep your fish healthy, but Bettas can definitely live without one. In fact, if you can’t afford one or if you don’t want to use one, you can simply opt not to add them to your tank.

    Additionally, there are other options available if you really want to add a bubbler but can’t afford one.

    For instance, we mentioned live plants and regular water changes above. These are two foolproof, absolutely cheap ways to keep your tank oxygenated.

    At the end of the day, it’s up to you whether or not you want to use a bubbler in your Betta tanks. If you decide not to, you can still do other things to keep the tank properly oxygenated.


    Betta fish are beautiful, vibrant creatures that make wonderful pets. They are relatively easy to care for and can be kept in a small tank, making them ideal for those who live in apartments or have limited space.

    While Bettas can live without a bubbler, we recommend using one if possible. Bubblers help to oxygenate the water and keep your fish healthy. They also help to keep the water clean and clear.

    If you can’t afford a bubbler or don’t want to use one, there are still plenty of other options available, like using live plants and making sure that you regularly change the water.
