Before, it was widely believed that Bettas could survive quite well without a heater or filter in a tiny bowl. Although there are very few instances in which a Betta does not require heating or a filtration system, it will require a lot more effort on your side. Do Bettas, then, require a filter? Definitely!
Betta fish do not require a filter since they naturally inhabit muddy water. However, muddy water does not always equate to unclean water. It is best to cycle the tank and maintain it clean, doing a regular 10% water change, just like you would with any other fish tank. If not, they will get fin, tail, and mouth rot.
However, if you continue reading, you will learn about the many kinds of filters and what they are used for. You will learn the major justifications for filters’ significance, what to do in the absence of a filter, and the consequences of choosing not to employ a filtration system in your tank.
Requirements For Betta Fish
Bowls are a common home for Betta fish. No filtration system and no heater, thus. The majority of the time, Betta fish thrive even when kept in tiny aquariums with no filtration or hot water.
Unfortunately, these very same Betta owners eventually find themselves puzzling about why their fish seems to be constantly stressed out or has a condition like fin rot. In bowls of still water, Betta may live, but it does not imply they are prospering.
Stress can be brought on by cold temperatures and unclean water, which increases the likelihood that your Betta will pass away too soon. However, this does not exclude you from keeping your fish in an unheated, unfiltered aquarium. It simply means that before choosing if it is the best course of action, you must completely comprehend the needs of your Betta fish.
Additionally, it implies that you must be prepared to put in more effort to maintain a fish tank that is unheated and unfiltered in prime condition.
Do Bettas Require Filters?
Betta fish thrive in aquariums with a filter. A Betta can be kept in a bowl, although I detest seeing it. You must actually keep up with weekly water changes, watch out for overfeeding, and maintain crystal-clear water. Additionally, you must maintain a room temperature suitable for tropical fishes, which is in the mid-70s.
When food spoils in a tiny dish, it happens quickly. Poor water quality can cause infections, fin degeneration, and, eventually, untimely death for your fish. Because of this, I strongly advise choosing a tank rather than a bowl if you are unsure.
Like other fish, Betta fish require clean water to survive. Filtered fish tanks have the ability to develop into small ecosystems, albeit these ecosystems do require some assistance from you.
Microorganism colonies grow in the aquarium and the filter, where they help to break down the waste of the fish and its leftover food produced.
In an aquarium with a filter, you do not need to, and you shouldn’t, perform a thorough water change because doing so will kill those beneficial bacteria. It is sufficient to vacuum the gravel and remove any algae in addition to a weekly water change of around 30 percent.
Simply said, filtration-equipped tanks require less maintenance. Additionally, the system is simpler to maintain the larger the tank. It is significantly simpler to maintain a 55-gallon tank than a 1-gallon fish tank. The oxygenation of the water is aided by the filter’s operations. Bettas like low-flow filtration because high-output filters frequently knock them about. For oxygenation, even just a low-flow filtration system will be helpful.
Why Are Filters Used?
Filters are meant to keep your aquarium free of any detritus, including rotting food, chemicals, bacteria, and decomposing stuff. As you can see, your tank has a lot of dangerous elements that must be eliminated for the benefit of your Betta.
Your filter draws water into itself, then filters it by using a variety of media and sponges to eliminate these harmful elements. Once everything has been processed, the water will be hygienic and suitable for your Betta.
Even while a filter is still required, you will not need to replace the water as frequently, which is undoubtedly a pleasant plus.
Motives For Filtering Your Betta Tank
You need filtration for your Betta aquarium for a variety of reasons. Here are some of the more significant ones.
Getting Rid Of Nitrates, Nitrites, And Ammonia
The primary objective of a filter in a Betta tank is to prevent the accumulation of ammonium, nitrites, and nitrates. Your Betta will suffer if any of these pile up in your tank to an unhealthy level. Your Betta’s immune system will deteriorate and be stressed out in particular by ammonia. Ammonia will actually kill your Betta if left unchecked for too long. (Also referred to as ammonia toxicity.)
The great news is that your filter’s sponges will include beneficial bacteria that consume nitrates, nitrites, and ammonia. And the ratios of all three will stay within safe ranges as soon as there are sufficient beneficial bacteria. The bacteria will continue to flourish in your filter even if it can also be detected in your aquarium.
Water Is Moved About.
Without movement, water will rapidly become stagnant. Water absorbs carbon dioxide from the air when it is left to stand for too long. This carbon dioxide will not only harm your Betta but also change the pH of your aquarium. While an air stone may be used to get around this, using a filter is still much more practical.
Oxidize Your Tank
Not only would utilizing a filter prevent water from becoming stagnant, but it will also provide other advantages. Additionally, the movement will oxygenate your tank. For Bettas with a labyrinth organ, this is less significant (an organ that allows them to breathe from the surface of the water). However, the plants and any other species you have in their aquarium depend on it.
Will You Need To Change The Water Less Frequently ?
As was already noted, you will not need to do water changes as frequently if your tank has a filter. The primary benefit of changing your water is that it aids in getting rid of any dangerous germs and chemicals while also diluting any that may already be in your tank. This implies that you will not need to replace the water as frequently because filtration also does this.
It still has to be changed, though. None of the essential nutrients and minerals that your Betta requires will be restored if you do not change the water often. Over time, your Betta will suffer if the water is not changed.
Without An Aquarium Filter, What Happens To Your Betta Tank?
Your Bettas will be capable of surviving without a tank filter for a while. Additionally, you may prolong this duration even further by doing regular water changes. However, if you decide without installing a filtration system in your tank, you should expect a significant reduction in your Betta’s lifespan.
First off, the water will never be as clean without a filter. Additionally, your Betta would become stressed out by the frequent water changes required to maintain the environment as clean as possible. In addition, it would greatly increase the number of instabilities in your aquarium.

What Are The Various Filtration Techniques?
Your filter uses three primary filtration techniques to keep your water pure. These three types of filtration include mechanical, biological, and chemical. Mechanical filtration clears out any dirt and debris that could accumulate in your aquarium, biological filtration gets rid of any hazardous bacteria, and chemical filtration gets rid of any dangerous chemicals. Here is more information on the various approaches.
Biological Filter
By processing and converting fish waste into less harmful chemicals, microorganisms and other microorganisms carry out biological filtering. Ammonia is transformed into nitrates, and these nitrates are then transformed into nitrites.
The only option to guarantee tolerable water conditions without biological filtration is to do frequent water changes, often twice daily (depending on the size of the aquarium and the bio load). When your tank is “cycled,” biological filtration begins to work. A tank that has been let to rest for 2-4 weeks so that nitrifying bacteria can colonize it is referred to as a “cycled tank.”
For detoxifying bacteria to colonize, aquarium filters’ physical areas and surfaces are ideal habitats. To promote bacterial growth, aquarists frequently include “filter media” inside the filter.
Mechanical
By forcing water through “filter media,” which functions as a strainer, mechanical filtration is accomplished. The filter medium, which the aquarist may then clean, traps larger, free-floating particles.
Filter floss, disposable filter pads, sponges, and gravel are a few examples of filter media (under gravel filters). The purity of the water in your aquarium will depend on the size and concentration of the filter media.
A sponge with wide pores, for instance, will filter out large particles, but a sponge with small holes will nearly entirely filter out the trash. Denser sponges require more frequent cleanings, but they also clog more quickly.
Chemical
In order to remove certain poisons or pharmaceuticals from the water, chemical filtration entails adding carbon or biochemical resins to a filter.
Filters frequently include activated carbon, which efficiently eliminates various metals and chemicals from the water. To maintain its effectiveness, activated carbon must be replaced on a regular basis (at minimum once every 60 days).
Activated carbon cannot take the position of biological filtration since it cannot remove ammonium, nitrate, or nitrites. A cycled tank is still necessary for the best fish health.
Can Betta Fish Thrive Without A Filter?
Yes.
But consider this. A fish in a dish is comparable to a driver who is unable to pull down his windows. Eventually, the air in the automobile becomes quite stale, particularly if emissions are leaking in. Without a filter, ammonia quickly accumulates in tiny bowls or tanks, necessitating more frequent water changes than in a tank with a cycling sponge filter. Aquarium filters move the water while giving the nitrifying bacteria in the filter media a place to live. These bacteria lessen the need for frequent water changes by breaking down harmful ammonia. The optimal Betta fish aquarium has a filter as opposed to one without.
However, use caution while purchasing any old filter.
Strong currents are not a good fit for a Betta fish’s long, flowing fins. Your Betta can weaken and perhaps pass away if he is continually fighting against a current.
Can Betta Live In A Bowl Without A Filter?
Even though most bowls cannot fit an ordinary aquarium filter, Betta fish can still be effectively kept in fishbowls.
Therefore, a Betta fish may really survive in a bowl without a filter.
A little dish with an aquarium filter running through it will also result in more harm than good. Given that your fishes are not the finest swimmers, the current may certainly stress and toss your fish about.
Proper maintenance is essential for your pet to live in such a setting. So much so that many novice fish keepers believe that bowls require less maintenance and are less pricey, which causes Betta fish to be neglected, resulting in diseases and a shorter lifetime.
Without A Pump, How Can I Supply Oxygen To My Water?
Options For Fish Tank Oxygenation Without A Pump
- Include actual aquarium plants.
- Use a powerful filter with a flow rate you can control.
- Stir up the water’s surface more.
- Increase the area of the water.
- Keep fish that can move across the tank’s various levels.
- Water changes and cup technique (for emergency situations)
Can The Filter Current Be Too Powerful For A Betta?
A Betta quickly becomes exhausted and upset if the intensity of the filter current is more than it can manage. With its big fins, the Betta would thus find it exceedingly difficult to swim and may be forced to hide or hopelessly lay at the bottom. Betta’s fins might potentially be harmed by the strong water movement.
The Betta can quickly drown if its fins are improper. Therefore, even though a powerful filter will not always kill Betta fish, it might hasten their demise via tiredness.
The Best Aquarium Filters For Bettas
Filters should be less strong in smaller Betta aquariums. But how can you choose the right filtration system for your specific aquarium?
According to the number of gallons in the fish tank, these are the leading water filters for Bettas:
Betta Fish Tank Filtration For A 3 Gallon Tank
The XINYOU XY-2835 Fish Aquarium Mini Cylinder is a good choice for a 3-gallon fish tank with a Betta because it does not create a lot of currents. It provides your Betta with quiet and clean water in that little area. The Betta fishes will always appear radiant and energetic in water that is consistently clean.
Most of the 3/4-inch filter is made of a sponge. However, the sponge is too soft to damage Betta’s delicate fins, and there is no discernible filter current. It is very simple to clean the device; all you have to do is squeeze out a portion of the old water and clean the absorption tube.
Once more, it is simple to set out and is ideal for a beginning. To prevent killing the helpful bacteria that are present in the filter, remember to wash it with dechlorinated water.
5 Gallon Betta Fish Tank Filtration Unit
You should still choose the XINYOU XY-2835 Fish Aquarium Mini Cylinder for a 5- or 5.5-gallon tank.
It is also quieter yet just as efficient at purifying the water in a fish aquarium this size. The Betta may take pleasure in swimming back and forth among the soft bubbles since it maintains the water perfectly pure. This water filter, not just for Betta fish, is, in my opinion, the finest for the majority of species housed in tiny aquariums.
To maintain the unit on the tank bottom, some weight is placed on the bottom of the device. Squeezing the filter while it is immersed will solve the issue, albeit if it appears as though it could float.
10 Gallon Betta Fish Tank Filtration Unit
The Marina S10 Power Filter would be a suitable filtration system option for a 10-gallon tank with a Betta.
Citing this item is the ideal option because of its relatively small, compact, and exquisite design, which not only makes sure it takes up less room but also enhances the appearance of your aquarium. It is simple to set up and much simpler to add customized material too.
The cool variable flow frequency that it offers is the nicest piece of news for your Betta. Once its engine has submerged in the tank water, it functions silently. The Betta can swim across the light stream without worry. Just in case, there’s a sponge covering the intake to keep your Betta’s fins from being sucked in.
20-gallon Betta Fish Tank Filtration System
One filtration system that effectively operates for a 20-gallon tank with a Betta is the AquaClear 30 Powerful Filter.
The first benefit of a Betta is its customizable flow rate. Second, compared to other similar filters, its filtering volume may increase to seven times that much. This is because of its multi-stage filtration technology, which effectively combines chemical and biological filtration.
This makes this filter one of the greatest options for a Betta tank of this size since it guarantees the water is always incredibly clean. Additionally, none of these procedures create turbulence, which is good for Betta’s fins. In addition, the AquaClear 30 creates a symbiotic interaction between the fish and the helpful bacteria that reside on the filter bed.
It is very simple to clean, and doing so does not require taking the entire device out of the tank.
FAQ
Will My Betta Be Alright For A Day Without A Filter?
Your Betta will indeed be able to cope without a tank filtration system for a while. Additionally, you may prolong this duration even further by doing regular water changes. However, if you decide without installing filtration in your aquarium, you should expect a significant reduction in your Betta’s lifespan.
Can A Betta Fish Without An Air Pump Survive?
Need Betta fish to breathe? In contrast to most aquarium fish, Bettas have a unique breathing system called a labyrinth in conjunction with their gills, which allows them to thrive without an air pump. They can breathe very little air outside of the labyrinth. Bettas can thus be housed in bowls without the need for an associated air supply.
Are Filters Or Heaters Required For Betta Fish?
Bettas must have heaters to stay warm as they often live in tropical environments year-round. Bettas are far more resistant to cold than other tropical fish because of how fast the temperature may vary in the small canals and ponds where they reside.
What Kind Of Filter Is Most Suitable For Bettas?
A high-throughput filtering solution for Betta aquariums of almost any size is canister filters. A pressurized canister and a spillway or spraying bar are used to return the water to the tank after it has been pumped out of the tank by this kind of filter. Canister filters may now offer the highest water flow rates as a result.
Conclusion
After all of this, the field is now in your favor. It appears that filters are necessary for Betta fish for a variety of reasons, including a long healthy life. For the sake of both you and your pet, it is definitely preferable to give them one.
Bettas have a more attractive appearance when they reside in a healthy habitat since that encourages a more vivid coloring. Even if they may experience adversity, it will eventually have an impact on their well-being.
