We can all agree Betta fish are often sold as easy-to-care-for, low-maintenance pets. And while they are generally hardy fish, they still produce waste like any other fish, and their tanks will eventually need to be cleaned.
The waste your Betta generates decomposes and turns into ammonia, which is toxic to your fish. Cleaning your Betta’s tank regularly will help eliminate harmful waste and clear ammonia and other toxins out of the water reducing the chances of your *betta getting sick. And the cleaning process is relatively easy.
It can even be fun to keep your Betta’s home looking neat!

Before we begin, you’ll need a few things to clean a tank correctly.
1. Gather Everything You Need
Before you start, you should take the time to get all the equipment you’ll need to clean the tank.
Below is a list of some of the things you’ll need to complete the steps below.
2. Prepare Your Water Ahead of Time
When you clean your Betta tank, you’ll want to perform some water changes. Whether you’re changing 10%, 20%, or 50%, you should have your water already prepared before you start the cleaning process.
Like all fish, Bettas can’t survive in unconditioned tap water. So if you’re using tap water, put the amount you need in a container and use a water conditioner to neutralize chlorine and other chemicals harmful to your fish.
You can also leave tap water out for 24-48 hours, and the chemicals evaporate naturally.
No matter what kind of water you’re using, you’ll want to bring it as close to your tank temperature as possible, either by letting it sit out for a few hours to get to room temperature or by using a heater.
Remember: When cleaning the tank, always wash your hands with warm or hot water to be safe. This will help remove and kill harmful bacteria and chemicals left on your hand or arms, keeping your pet healthy.
3. Washing Hands And Putting On Gloves
Before you even think of putting your hands into the take, make sure you wash them. Oh, and don’t use soap.
Wash your hands and arms (up to your elbows) with warm water for about three minutes.
This will help remove oils, perfumes, or dirt on your hands and arms.
4. Remove Betta Fish From Tank
Before cleaning, you’ll want to remove your Betta fish from the tank and put him somewhere calm and safe.
Fill a bowl or cup with tank water, and use a small fishnet or sterile container to scoop your fish out of the tank gently. Put him in the tank of water you’ve set aside, and he’ll have a place to swim around while you clean his living space.
Make sure you place a cover on top of this container. Betta fish are fantastic jumpers.
5. Remove Decorations
Next, remove all the tank’s decorations, accessories, plants, and hiding places. Taking these out will make cleaning the rest of the tank more straightforward, and many items will need to be cleaned.
Set aside everything in a large bowl to keep them together and to make cleaning easier.
6. Turning Everything Off
7. Remove Tank Water to Save
Start a siphon, remove a portion of the tank water, and set it aside. Suppose you’re doing a 50% water change; set aside half the water in the tank. Suppose you’re doing a 10% water change; set aside 90% of the water in the tank. You’ll be adding this back in when you’re done with the cleaning.
When *changing water, so you should always keep some original tank water to add back.
Your tank water has built up beneficial bacteria over time, and it’s the environment that your Betta is used to. So a sudden, drastic change to that environment could send him into shock.
8. Pour Out Remaining Water
Once you’ve scooped out the water you’re going to save, the rest of it can be dumped. Slowly pour the water out, ensuring your gravel doesn’t fall out.
You can also pour the water over a sieve or strainer to catch anything that falls out while dumping it. Finally, pour your gravel into the bowl holding your tank decorations.
9. Clean Decorations
Run warm water over the decorations and accessories from your tank. Then, use a soft scrubber or brush to scrub off any slime and dirt stuck to the surface.
Do not use soap on the decorations or anything else in your tank. Even if you rinse it off well, soap residue can remain and harm your fish.
Once you have finished rinsing your decorations, set them aside on a clean paper towel.
10. Clean and Scrub Tank
The next thing to clean is the tank itself. First, put the tank in your sink and run warm water into it. Next, scrub the bottom and sides of the tank with a soft brush to loosen any accumulated dirt, *algae, and slime.
Make sure you give the corners a good scrub.
Again, do not use any soap on your Betta tank. Once you’ve scrubbed everything, dump the water and give the tank a final rinse.
When removing algae, it’s best to scrape the glass before you start to vacuum the substrate; this is because as you start the siphon, you’ll also remove some of the algae particles that are now floating in the water.
To remove algae, use a scrub pad or razor for stubborn algae, or you can try an old credit card for an inexpensive method.
Wash hard-to-reach places
Do your best to get right into the corners of the tank and other hard-to-reach places where algae and debris may accumulate.
11. Vacuum the substrate.
A lot of the waste and debris in your Betta tank accumulates in the gravel, which can be the dirtiest part of your tank.
Run warm water over the gravel while gradually rubbing your hands through it to loosen slime and dirt. Once you have given the gravel a good rinse, drain the dirty water from the bowl. You can also place the gravel in a sieve or strainer so that water drains while you rinse it.
Repeat as many times as necessary until your gravel is completely clean.
12. Cleaning The Filter
Cleaning your filter is a simple process.
Remove the filter media and wash it with old tank water. Then you can reuse the media or replace it as needed.
While the filter media is out, ensure to clean out the filter box as well as the input/output tubes.
This will help improve the overall water flow of your filter.
13. Put Gravel and Decorations Back in Tank
Now that you’ve cleaned your tank, gravel, and decorations, you’re ready to put everything back together.
First, pour the gravel back into the bottom of the tank and arrange it, so it’s evenly spread out.
Next, put in your decorations and accessories and arrange them how you want. For some cool setup ideas.

Finally, reattach any heaters, filters, thermometers, and anything else you removed before cleaning.
14. Refill The Tank
Slowly pour the old tank water you set aside back into the tank, so you don’t disturb your gravel and decorations. Then, fill the rest of the tank with the freshwater you prepared earlier.
Give everything a stir to mix the water, reposition any decorations that may have fallen over, and test your *temperature and pH to ensure it’s ready for your fish. You’ll want the pH and temperature to be close to what your fish is used to.
15. Put Your Betta Fish Back In
Now that you’ve got everything clean and backed where they belong, it’s time to reintroduce your Betta fish to his home.
To do this, take the container he’s in and place it in the tank. Then, slowly tilt the container until your Betta can swim out on his own.
Be careful when doing this so he doesn’t damage his fins. Your Betta should be happily swimming around his newly cleaned tank.

Frequently Asked Questions
How Often To Clean Your Betta Fish Tank
How often you need to clean your Betta’s tank depends on the tank size. Smaller tanks accumulate toxic levels of waste more quickly and need much more frequent cleanings and water changes. For example, you may change out 30-50% of the water every few days and clean the tank once or twice a week.
Larger tanks with filters need less frequent water changes and even fewer cleanings. It’s a good idea to change out 10-15% of the water every week or two, and your tank can go several weeks without a complete cleaning.
Thoroughly cleaning your Betta’s tank may initially seem intimidating, but it’s pretty simple. Here are the supplies you’ll need:
- Containers for fish, water, and gravel/decorations
