There is a proverb that betta can live in a tiny bowl or tank without having any filter. This is completely true and fine. Their labyrinth organ lets them survive by breathing atmospheric air.
The case is very rare that your betta doesn’t need any filter. The answer isn’t simply yes or no. But I personally hate to see it in a bowl. Bowl water is contaminated so quickly that it can cause fin damage, infection, and death. I encourage you to go for a fish tank.
So, do betta fish need a filter? Definitely mate! Soon you will learn all the important facts, keep digging.
Using a filter in a small tank can be a bad idea rather than a good one. This can create more than enough current, which will make them feel stressed. Betta fish do not like hard waves in the water when filtered in a small tank.
Otherwise, if you don’t add a filter, uneaten food and feces soon produce ammonia, nitrate, and nitrites in the water. Continuing this for a long time causes fin and tail rot. If you think about constantly changing the water, the betta may endure more stress. So go for at least a 5-gallon tank with a filter to start.
Well, you need to add a filter as it prevents increasing ammonia, nitrite, and nitrate. When they build up too much, you will notice the water is dull and cloudy. Don’t be happy if you see this. Because they can infect your betta very badly – failing the immune system and increasing stress. If this goes on for long, your betta will die from ammonia poisoning.

However, the use of a filter helps the bacteria growth, which regulates these three in water levels.
If the water stays stagnant for a long time, it will increase the carbon dioxide in the tank. Excessive carbon dioxide increases the pH level and causes your fish to die. An air stone can solve this problem but using a filter is more effective.
A filter not only stops stagnation it also helps increase the potential levels of oxygen in your tank. Though this is not very important for betta (because they have labyrinth organs), it also keeps other fish and plants well.
Betta fish love a tank with a filter, it helps them to maintain their immune system and keep them free from stress and diseases. Let’s see the quick shoutout benefits of filters.
Do betta fish need a filter? It depends on different circumstances. If you don’t have enough time for maintenance, I personally recommend it with a large tank. This will make it much easier for your betta to maintain a healthy ecosystem and balance.
