Do betta fish need air pump?

No, betta fish do not need an air pump. Betta fish are labyrinth fish, which means they have a special organ that allows them to breathe air from the surface of the water. In fact, an air pump can actually be harmful to betta fish, as it can create too much turbulence in the water and stress them out.

However, if you have a heavily planted tank, an air pump can be beneficial in providing circulation and oxygenation to the water. Just make sure to place the air pump in a way that it does not create too much current.

Here are some additional tips for keeping betta fish healthy:

* Provide them with a tank that is at least 2.5 gallons in size.

* Keep the water temperature between 75 and 82 degrees Fahrenheit.

* Provide them with a variety of foods, such as live or frozen brine shrimp, daphnia, and bloodworms.

* Change the water in their tank once a week.

* Avoid overcrowding the tank with other fish.
