Do Betta Fish Need A Filtered Tank in 2024? Whether betta fish require filters or not is dependent on many factors such as the size of the tank, the degree of care, tank mates, and many more. There isn’t a straightforward “yes or no” answer, as they can live and succeed in both cases provided they are treated with care.
Problems are caused by misinformation and the assumption of novices that an empty bowl or another small tank will require more work-friendly and less costly.
This isn’t true at all and could lead to an unwell betta or even worse. Before you decide on filtration, be sure that you have read and understood the advantages and disadvantages of each.
Let’s begin by understanding the habitat of bettas which is rice paddies and shallow bodies of water. In times of drought, wild bettas could even be stranded in a muddy Puddle for a short period of time, with limited oxygen.
Betta fish can endure these conditions via evolution, thanks to their unique ability to take oxygen out of the atmosphere (at the surface of the water) in lieu of depending on their gills. This is due to their labyrinth organ. It classifies these fish in the category of Anabantoidei (also known as labyrinth fish).
Due to their endurance in water with low oxygen levels, They are highly desired and are recommended for those who are new to the sport. They are less difficult to handle as compared to other fish species that require smaller equipment, but misconceptions are all over the place.
The claim is that they prefer smaller habitats and live from the roots of a plant vase. These assertions are not true and could result in your betta just being able to survive. You want your beta to be able to enjoy a lengthy, well-balanced life with no pain is that right?
Do Betta Fish Need A Filtered Tank To Survive?

Betta fish prefer tanks that are filtered to rid the water of any waste such as particles, decayed or uncooked food, feces, or dangerous particles. Another advantage of filters is that they improve the water’s quality by cycling the water which helps oxygenate it and keep the pH level stable.
But, it will require lots of work from your side. You’ll have to keep up with regular water changes and introduce beneficial bacteria that feed on the waste of your fish. Additionally, you’ll need to use an air stone in order to stir the water in a gentle manner. In any case, it’s better for the fish to make use of a water purifier.
What Happens to an Unfiltered Tank?
Tanks that weigh 2.5 Gallons or less aren’t required to have a filter since they could cause much more damage than benefit. Filters in small tanks can cause powerful currents that can throw betta fish about and strain them out.
If you keep your Betta fish in a small tank with no filters, the fish can’t have a long and healthy existence unless you change the water regularly. Even when you do the right thing, your fish could end up dying suddenly if the water gets too polluted at certain points.
In fact, bettas take in air by using their labyrinth organs however, they aren’t able to depend solely on it therefore the tank water needs to have oxygen.
You are able to do without the use of a filter for a time If you’re willing to regularly change your water. However, this can have an effect on the easily-aggravated Betta fish, particularly due to the unstable water that frequent changes in the environment create.
After a while, massive amounts of stress can be harmful to your fish betta. When coupled with waste from fish this can cause death.
Bettas are not the most powerful swimmers, and their fins that are long could make mobility difficult when there is a strong current. Betta prefers calm or slow-moving water. This is the reason why some caretakers opt for non-filtered tanks for their bettas, resembling their natural habitat.
However, the quality of water is rapidly deteriorating in low-volume, unfiltered tanks. The bigger the tank the greater the volume, the less the decline in water quality, and the more simple it will be to keep it in good condition.
Feces and food that are not properly cleaned cause ammonia, nitrogen, and nitrites to accumulate. If they are in large quantities, they could create stress and cause your betta to become sick.
The most frequent issues in smaller tanks that are not filtered are fin and tail rot. There are beneficial bacteria that are naturally present inside the aquarium.
The constant water changes can deplete beneficial microorganisms, and cause stress in the process.
The minimum tank size required for the beta fish is 2.5 Gallons, with the suggested size of 5 gallons or greater. The care of a beta fish without a filter can be a lot of work. Tanks that are not filtered require 2 to 3 water cycles with a water volume of about 25 percent and then an all-water change each week (depending on the water’s quality). In contrast, the 5-gallon tank that is not filtered will require only one water cycle each week at approximately 25%-35 percent of the total volume, and a 100 percent water change every month.
It is also recommended to make use of test strips to evaluate your water’s parameters in real time. To assist with tanks that are not filtered clean out food particles and poop prior to it settling and degrading.
(pro tip: Use an aquarium turkey baster that is designed to effortlessly suck the debris out from the aquarium).
If you read the article below you’ll soon understand the reasons why tanks that are filtered can be beneficial to Betta fish and are easier to keep clean.
