Does Betta Fish Need an Air Pump? (Bubbler Benefits and Drawbacks)

As a fish owner, you must know if your betta fish need an air pump to live happily in your tank. While bettas are known to survive in low-oxygen habitats, it is far from optimal or ideal!

If you want your betta to be happy, you should learn more about betta fish care. In this article, we’ll dive (pun intended) into the ins and outs and everything you need to know about whether betta fish need a bubbler and explore the necessities for your favorite pet fish.

What is an Air Pump and How Does it Benefit Betta Fish?

If you want to act smart and impress your friends the next time you hang out, tell them that a fish tank’s air pump is also known as an aerator. That will, undoubtedly, make you the #1 biggest nerd they know. The air pump pumps air into an aquarium (or pond, if you have one of those) to increase the water’s oxygen levels.

You may wonder why oxygen is essential for a fish, but fish are like humans because they need oxygen to survive. Fish don’t have lungs to breathe but instead extract oxygen through water using their gills.

A fun fact about bettas: they are part of the labyrinth fish family and can breathe air through a unique organ called “a labyrinth,” but they also have gills. Please don’t ask me why. Evolution is weird sometimes.

An aquarium pump, or bubbler, keeps the water well-oxygenated, which benefits your finned friends in many ways: better digestion, improved blood flow, and keeps your betta healthy. A healthy fish is a happy fish that looks good swimming around your fish tank. Without a bubbler, the worst-case scenario is that your bettas are left gasping for air bubbles at the bottom of the tank. Don’t let your betta fish live without an air pump.

Alternatives to Using an Air Pump for a Betta Fish Tank

Pumps help regulate oxygen levels in a betta tank, but alternatives are available. If you’re considering alternatives to using an air pump in your aquarium, here are a few options:

  • Live plants can help to produce oxygen in the water naturally. The plants absorb carbon dioxide and release oxygen, creating a healthy ecosystem for your fish. Pick plants that are good for your betta fish, as some plants may be toxic, worsen the water quality or require special care.
  • Regular water changes can help to keep the oxygen levels up. Bettas need frequent water changes. It also helps remove any chemicals or contaminants that may harm your fish, such as chlorine.
  • Using an oxygenating filter. Some water filters help maintain oxygen levels in the water. Research to ensure your filter is designed explicitly for Siamese fighting fish.

Alternatives to getting an air pump may maintain proper oxygen levels for some fish species and may not be compatible with your betta fish tank. There are also air stones and dissolved oxygen emitters which work great. If you are still deciding, you can always consult a fish care expert or veterinarian about your aquarium setup.

Do you feel that an air pump is right for you? Ultimately, the decision depends on your setup and needs.

Factors to Consider When Deciding Whether to Use an Aquarium Pump for a Betta Tank

Here are a few key factors to consider before you decide whether your betta needs air pumps. These include:

  • Size and type of tank. A smaller tank requires less oxygen than a larger one.
  • Number of betta fish and other tank inhabitants. Tanks with lots of fish and sea animals need more oxygen than tanks with fewer fish. The tank may require a bubbler to keep your fish healthy if you have many.
  • Water temperature and pH levels can also affect oxygen levels. If the water is too warm or acidic, your betta fish may struggle to absorb the oxygen they need. A bubbler can help by increasing oxygen to compensate.
