Buyer’s Guide: How to Choose Your Betta Fish Tank

There are several things you’ll want to keep in mind when shopping for the perfect home for your Betta.

1. Tank Size

There is a lot of misinformation on the internet that suggests that Bettas can live comfortably in small bowls or tiny, one-gallon tanks. This is not true, and the minimum size you should consider for your Betta is a five-gallon tank.

Like all fish, Bettas need space to swim and explore. Small tanks also make maintaining healthy water quality significantly harder, so aquariums under five gallons can quickly lead to unhealthy or fatal spikes in ammonia, nitrites, and nitrates.

You can opt for a tank larger than five gallons. Bigger aquariums will give your Betta more room to move, and they may be able to support additional fish, shrimp, or snails, making your tank more exciting and enjoyable. Ten- and fifteen-gallon tanks should include some plants and decorations, as wide open spaces can cause Bettas to get stressed.

2. Filtration

Contrary to popular belief, Betta tanks should always have adequate filtration. All fish species create waste and leave food particles behind, which can break down in your water and leave harmful chemicals like ammonia behind.

Many beginner tanks and aquarium kits include filtration systems, so you’ll only have to purchase a filter separately if yours doesn’t. Some Betta tanks are self-cleaning so this could be an option if you’re looking for the lowest maintenance option.

Rear-hanging filters are often visible in your tank and can detract from the natural beauty. They can be a bit noisy, but they take up limited tank space. Submerged canister filters are silent, but they take up a lot of room within your aquarium. Canister filters are usually better for tanks that are at least 10 or 15 gallons, but it is mostly personal preference.

3. LED Lighting

Bettas thrive in areas where there is sunlight during the day and darkness at night. Your climate or living space may not allow for this, so an LED light is an excellent addition to a Betta tank.

Many beginner kits include LED lights that can simulate natural sunlight. This keeps your Betta happy and healthy.

4. Tank Heater

Bettas thrive in temperatures in the mid- to high-70s. For most aquarists, this means a water heater is a necessity.

Some beginner aquarium kits include a heater, but most don’t. You’ll want to purchase one separately and make sure it can handle your tank’s volume.

5. Style

Some tanks are plain and rectangular, while others have dramatic, curved edges and bowed panels. The style won’t affect your Betta much, but you should choose a tank that appeals to you and makes sense with the room in which you plan to keep it.

6. Budget and Reviews

Lastly, you should consider the total cost and the reviews a tank has online.

When considering the tank’s price, make sure to pay attention to what is included and what pieces of equipment you’ll need to purchase separately. If your tank doesn’t come with a heater, filter, lid, and LED light, those necessities can quickly bump your total cost over your budget.

The reviews a tank receives online can be a great source of information. Pay close attention to flaws and shortcomings other customers have found before you make your purchase.

Why Using Bottles, Bowls, and Vases for Betta Tanks is Not Ok

Many people have been told that Bettas can live and thrive in tiny environments. This is false. You should, above all else, avoid housing your Betta in a bowl, bottle, or other small container or tank. All fish need room to move around, exercise, and explore, and Bettas are no exception.

Additionally, small tanks – even those that are 1-2 gallons – are prone to dangerous spikes of ammonia, nitrites, and nitrates from Betta excrement and leftover food. Small tanks and containers are not suitable for Bettas and can quickly kill them.

What to Know About Betta Fish When Planning Your Betta Tank

Betta fish are relatively straightforward to keep and are suitable for beginner aquarists. However, there are some important things to keep in mind when planning your first Betta tank.

1. Males with Other Bettas

You may have heard that you can’t keep multiple Betta fish in a single tank. This is partially true, primarily because male Betta fish are very aggressive toward other Bettas and will often fight to the death to maintain control of their territory.

You should avoid keeping a male with any other Bettas.

2. Female Betta Fish Sorority Tank

Unlike males, multiple female Bettas can live together. Five to ten females in one tank make up what’s called a “female Betta fish sorority tank.” The fish may take some time to get used to living together and form a pecking order, but they often work well together in time.

Keeping females together is possible for beginners, but you’ll want to make sure your tank is large enough to support the added fish load.

What Do Betta Fish Need to Be Happy in Their Tank?

Betta fish need few things to thrive in their environment. The most important things are:

  • Proper water temperature between 74 and 79 degrees
  • Good filtration to remove water pollutants and harmful chemicals
  • Plenty of room to swim, explore, and exercise

A five-gallon tank with a reliable water heater and filter should help your Betta thrive.

Besides these necessities, Bettas feel happiest when they receive plenty of natural or simulated daylight during the day and darkness at night. A powerful LED light should do the trick. They also need regular feeding, and they seem to enjoy some human interaction as well. If you’re planning to go on vacation, consider purchasing an automatic fish feeder to make sure your Betta stays well-fed.

Betta Tank FAQs

How Do You Clean a Betta Fish Tank?

In addition to constant filtration, Betta tanks need regular cleaning just like any other aquarium. We recommend using a good aquarium vacuum to clean the substrate and vacuum the sides of the tank.

How Often Should You Clean a Betta Fish Tank?

You should plan to clean the substrate in your Betta tank every other week with an aquarium vacuum and clean your filter on the opposite weeks. Plan to do a 25-50% water change once a month.

How Big Should a Betta Fish Tank Be?

Betta tanks should be at least five gallons. Smaller tanks and bowls should be strictly avoided, and larger tanks should contain ample decor or plant life to provide a sense of security.

How Long Do You Have to Wait to Put a Betta Fish in the Tank?

You should cycle your Betta tank for six to eight weeks before introducing any fish. Once cycled, submerge the closed bag with your Betta inside in the water for about 45-60 minutes to allow for a smooth temperature transition before releasing your fish.

Do Bettas Like Tall or Long Tanks?

Long tanks are generally better for Bettas, as they more closely resemble their natural habitat. However, they will be happy in most tanks that are an appropriate volume.

Will a Betta Be Happy in a 5 Gallon Tank?

Five gallons is the minimum recommended tank size for a single Betta. They will usually thrive in this environment and shouldn’t be placed in anything smaller.

Is It Cruel to Keep Betta Fish in Small Tanks?

Not only is keeping your Betta in a bowl or small tank cruel, but it’s likely to cause them illness, sadness, or even kill them. Avoid tanks smaller than five gallons for your Betta at all costs.

How Do You Know a Betta Fish is Happy?

Happy and healthy Bettas will be very active in their tanks, and they’ll have a hearty appetite. Some – but not all – Bettas will exhibit a bright color when tank conditions are optimal for health and happiness.

Do Bettas Like Light?

Bettas naturally live in sunny areas of Asia in shallow streams and ponds, so they’re used to heavy sunlight during the day. As such, your Betta will be happiest if they get ample light during the day and darkness at night.

Conclusion – What is the Best Betta Tank for Me?

The best Betta tank will be one that is suitable for your fish and your home. It should be at least five gallons and should include an LED light, a heater, and a filtration system that can keep up with cleaning your water.

Our favorite Betta tank is the Fluval Edge 2.0 Black Aquarium Kit. It’s a gorgeous tank that is large enough to help your Betta thrive. It includes a bright light and excellent filtration system to provide the best water conditions for your Betta fish.
