We’ve shared some of our favorites here to give you a variety of options for the best betta fish tank on the market. You will notice that the majority of these come as a kit. This is pretty common when it comes to choosing a tank but you can also find them without a kit as well if that is your preference.

We shared a variety of sizes, shapes, styles, and even features so be sure to browse and find what really appeals to you or will work best for your setup. We hope something here works as a solution for your needs!

If you’re still not sure just what you want or need, we have some tips and pointers that just might be helpful for you. In this section, we’ve put together a buyer’s guide to offer you some helpful information to consider while you peruse your options.

None of these will tell you exactly what to get but they provide reasonable suggestions and points to consider that just might help you narrow down your options more and really choose the best for you!

Best Aquarium Guide: Choosing the Best Tank

Size Options

One of the first things that you will want to consider is the size of the aquarium or tanks. It’s not just about how much water the aquarium can hold but also about how much room your betta has to move around. Bettas do like a lot of room so choosing an aquarium that gives them plenty of room to move around in the water really does make a significant difference.

At the same time, we don’t all have the room ourselves for an enormous 20 gallon aquarium with all of the works. If this IS what you want for your tanks then that is totally awesome but it isn’t for everyone. Before you choose your aquarium, consider how much water you need or want to deal with and where you are going to place it.

Do you want to grow plant life with your betta in the aquarium or do you just want something simple for a betta? Tanks come in all sorts of shapes and sizes from around 2 gallons up to giant tanks that are 100 gallons. You don’t need those extra large aquarium sizes for a betta but they are an option.

For a betta, the recommended aquarium size is around 5 gallons. A 2 gallon is suitable and a 10 gallon works fine also but 5 is the most common and recommended size for a betta. We really don’t recommend that you go higher than 10 for a single fish as it simply can be just too much water and area. It won’t hurt the fish but it is excessive for aquarium and water care when you think about the big picture and all of the details.

Let There Be Light!

Your betta needs light, just like most fish do. The light and the filters work to regulate the temps of the water and to help the plant life and the fish thrive in the environment. Light is not just to provide light within the tank. There are other purposes.

You should plan to have plants in your aquarium and all of the contents will benefit from a light. We recommend LED as this is the most efficient and effective light source for an aquarium. They work well with water.

LED lights offer nutrients and actually promote the health of your aquarium contents. In our aquarium choices, you will notice that the majority of them include a lighting option. You can always upgrade or change it out but it’s nice to be able to choose a kit that comes with all of the things so you don’t have to purchase piece by piece.

Lights are essential and if your aquarium includes them as part of the lid that is even better because they just tend to be more aesthetically pleasing when they are incorporated in that manner instead.

Budget

Purchasing an aquarium or a tank or a kit for your betta fish can get pretty pricy. If you just buy the aquarium, you have to buy all of the things to go with it and that can add up quickly.

You can find quite a variety of prices and price ranges and they all have something unique or interesting to offer. When you are ready to get an aquarium for your betta fish, keep the best budget range for yourself in mind.

You can purchase affordable options that are truly the best for you and they will still be a great aquarium choice. You don’t necessarily have to buy the best premium aquarium to have the best available.

There may be times that you notice a difference in quality for the cost. You want to choose the best for your budget but you also want the aquarium to be a good value for the money that you spend. For every aquarium here, they are all great – even the budget friendly options are among the best out there!

Fish Bowl Vs. Aquarium

A lot of people think that a simple glass fish bowl will be suitable for a betta but that really isn’t the case. Your betta really does need an aquarium. It needs a decent amount of room to move around in and it needs the filtration and air that an aquarium system would provide.

A bowl doesn’t offer any of that. No filtration, no room, and no lighting really is not a healthy place for your betta to thrive. Sure, they might stay alive for a few months but ultimately, if you want to treat your betta right, you actually need a fish aquarium with all of the things.

It might seem silly because bowl have been used for years and they seem effective but they really are not the best solution for a betta. Spend a little extra money and just go with an aquarium. If you’re not sure where you can place it, you can choose a smaller option and set it in the same spot you might have set the fish bowl.

Your betta will be happier and healthier and you have more room for things like plants. Plus, you have that filtration device that really saves a lot of water and effort for you as well. It’s a win-win!

Features

Finally, consider the features. You will see a lot of different features overall with your choices and they all will be unique in some way.

For example, you saw the Flex aquarium as our best overall option and it’s great! It has a unique style, which is one of the features. Then, you saw the Aqueon neon option with neon features. It’s also one of the best.

The features tend to be a matter of preference but we want you to be aware of them so you can choose any features that you specifically want or need or just really like while you make a decision.
