The best way to make sure you give your Betta a happy home is to think about its natural habitat. Bettas live in warm, somewhat shallow water.
In this environment, the substrate would be silt with plant roots shooting through.
There would also be bits of plants that have started to break down.
Bettas love this kind of environment.
It allows them access to the surface and gives them plenty of places to hide and find some shade.
Is it possible to recreate this environment in a home tank?
Not exactly. You can’t have plants rotting in the bottom of a small tank without causing a lot of problems with the water.
But keeping plants, whether real or artificial, in your tank is one way to make your Betta feel more at home.
Before you can add plants, you have to make sure you’re using the best substrate for Betta tank that can support them.

What Kind of Substrate for Betta?
There are a lot of things that determine what the best substrate is for your Betta. One of the most important ones it the size of your tank.
If you have a small tank are using a bowl without a filter, you will have to swap out the water fairly frequently. For bowls and 1 to 2-gallon aquariums, the water will have to be completely changed out pretty regularly. So, what does this have to do with substrate?
Think about it, if you’re regularly draining the water from your fish’s aquarium, a gravel style substrate is better than a sand based one. With sand, a little more disappears every time you empty it. You also have to wait awhile for everything to settle before you can put your fish back in his home.
Gravel substrate is great with larger tanks that don’t require 100% water changes. It allows everything to stay anchored without disturbing your fish’s habitat too much. Be wary of using large river rocks. Anything around ½ inch or so is fine but something larger could cause problems because it can more easily trap waste and uneaten food.
Another thing to consider is whether or not you’re going to use live plants. Live plants do better in gravel substrate for various reasons. In fact, there are good things and bad about both gravel and sand substrates.
Sand or Gravel for my Betta Tank: Which One would be Better?
Sand and gravel are definitely the 2 most popular choices when it comes to Betta substrate. Which one is better depends on how you’re setting up your tank and how much work you want to put into maintaining it. Let’s take a closer look at the pros and cons of each.
First, let’s talk about sand. If you’re going to use a sand substrate, make sure you get some from a trusted brand. A lot of sand used for this purpose is basically just what they couldn’t use for other things, like pay sand or construction materials.
That’s why it’s always best to go with a brand that specifically makes materials and supplies for aquariums. Don’t dig up your own sand or bring a bucketful back from the beach and think it’s okay to use in your tank, either. You always have to be careful about what you introduce into the water.
Some people really love the look of sand and it come in a range of colors. Whether you want a natural or funky look, you’ll be able to find the perfect color for you. It’s also smooth and easy to tuck plants and other decorations into and you can contrast it to your Betta to really make the colors pop.
In general, sand is a really clean choice. Because the particles are so small and get packed in so close together, it’s hard for uneaten food or waste to penetrate it. You might find some on the surface but that’s generally easy to clean up. Sand is also a great place for beneficial, natural bacteria to thrive.
What are the downsides to using sand?
For one thing, it’s really easily stirred up in the water when you’re cleaning and needs replacing pretty often. Also, pockets can develop where anaerobic bacteria can grow and cause severe issues with water quality.
This is easy enough to prevent, you just have to mix up the sand so that you keep air circulating through it. This eliminates the environment where this kind of bacteria can live just be introducing air to it.
Sand isn’t always the best choice for live plants, either. It’s dense and most plants aren’t easily able to force their roots through it.
Now, what about gravel?
Pebble or “pea” gravel is best. The substrates we chose in our reviews are all a good size. They’re somewhat small and rounded without any sharp edges and basically uniform in size.
This kind of gravel doesn’t clump together are easily as sand does so you avoid the pockets of anaerobic bacteria altogether. Plant roots can pretty easily push their way through gravel and it holds artificial plants and decorations better because it has more weight than sand.
Gravel is heavier than sand so it’s more difficult for your fish to stir up. It’s also easier to clean because it’s generally stays in one place, even if you have to change out all the water. Gravel is also available in many sizes, styles, and colors so you’re bound to find the perfect one for your Betta. It’s even a great home for colonies of beneficial bacteria to grow to help keep the pH of your water where it needs to be.
What are the downsides?
If you get gravel that’s too small, an enthusiastic Betta might mistake it for food and cause severe medical problems. One more thing, if you choose to feed your Betta live food, it’s really easy for it to get away and hide among the gravel. If you don’t keep a close eye on this, it could end up causing a big problem with water purity down this.
One thing we should mention, no matter what kind of substrate you use, it should be rinsed well before being introduced to your tank.
How Much Substrate for Betta Tank?
The actual amount that you need depends on the size of your tank. Generally, though, what you’re aiming for is for the substrate to be a certain height along the bottom of the tank.
If you’re planning to have live plants, you should have about 2 inches of substrate. For artificial plants, 1 inch is enough. But remember, that means 1 to 2 inches across the bottom of the whole aquarium, from corner to corner and front to back. You can also build up varied terrain if you want to make it a little more interesting for you fish. Add a pile here, a mound there to make it feel more natural.
It’s tempting to want to avoid substrate. After all, it makes cleaning the tank a lot easier and makes less work for you. That said, it’s important to think about the well-being of your pet. For one thing, a bare-bottom tank doesn’t give you anywhere for beneficial bacteria to grow. This kind of bacteria is so important to the balance of the water, especially if you’re using a bowl or tank that doesn’t have a filter.
Bettas naturally thrive in areas where there is abundant plant life and love to swim around to find shade and to explore. Without substrate, you don’t have anywhere to add plants of your own. Bettas can get stressed out by their own reflection and no substrate means they will be able to see themselves no matter where they are swimming. Plus, it just looks unnatural.
The only way to keep your Betta happy and healthy is to give them a good home. Choosing the right substrate is the best foundation for your tank, literally and figuratively. It fosters bacteria growth, supports both real and artificial plant life, and gives your Betta a true habitat to explore. The ideal home for your Betta truly starts at the bottom. Of your aquarium, that is.
