Betta fish are some of the most brightly colored aquarium fish, also known for their long, flowing fins. These fish remain fairly small and they do not require a significant amount of care, but they do need one thing – a betta fish tank that is appropriately sized. Do not fall for the misconception that bettas can be kept in small fishbowls. All aquarium fish require space to swim and grow, including your betta.

In this article, we’ll talk about tips for caring for betta fish and provide some tips for choosing the best betta tank. You’ll also see our top 10 picks for the best betta tanks.

What To Look For In A Betta Fish Tank?

Your betta fish will spend its entire life in its tank, so you need to choose wisely. Choose a betta tank that provides ample space for your betta fish to swim while also saving enough room for decorations.

Here are some important things to look for in a fish tank for bettas:

  • Durable materials. The last thing you want is to accidentally crack your betta tank during cleaning, so make sure you purchase one that is made from high-quality materials.
  • Appropriately sized. Betta fish can technically survive in fish tanks as small as one gallon, but five gallons is a much more appropriate size. Look for anything in the 3 to 5-gallon range.
  • Integrated equipment. Many betta fish tanks come with an integrated lighting or filtration system – sometimes both! When shopping for a betta tank, check to see what equipment it comes with and whether it is of high quality or not.
  • Additional accessories. Some betta tanks come with nothing more than the tank itself, but many are sold as complete kits that come with equipment such as lighting, heating, and filtration.

Tips For Keeping A Betta Fish

Betta fish are fairly easy to keep because they are small, adaptable, and don’t require a lot of space. As is true for any aquarium fish, however, your betta has certain needs that must be met. A safe and appropriately sized tank is the biggest requirement, but you also need to think about maintaining the proper tank temperature, keeping the tank water clean, and feeding your betta a healthy diet.

Here are some simple tips for caring for your betta fish:

  • Place your betta tank in a location where it will be easy to access and where you can enjoy it, but not in a high-traffic area where it might get knocked over.
  • Be sure to treat your tap water with a water conditioner to remove chlorine and heavy metals before adding your betta to the tank.
  • Install a tank light to illuminate the tank during the day – an LED light is perfect because they come in small sizes, are energy-efficient, and don’t produce heat.
  • Choose a high-quality filter for your betta tank to help keep the water clean and clear – it should provide both mechanical and chemical filtration, at least.
  • Keep the temperature in your betta tank at least 74°F – this may require you to install a tank heater if you don’t live in a naturally warm climate.
  • Feed your betta small amounts of a high-quality betta food twice a day – offer only as much as your betta can eat in 2 to 3 minutes.
  • Top off your betta fish tank as water evaporates every few days and perform water changes at least every two weeks to dilute waste products and keep the water clean.

Now that you have a better understanding of how to care for a betta fish, you’re ready to start tank shopping! Take what you’ve learned here to find the best betta tank within your budget.

Final Remarks

Choosing a betta fish tank doesn’t need to be a difficult decision. There are many wonderful options out there and most would be perfectly fine for your new betta. Consider what you’ve learned here about caring for a betta fish to help guide your decision. If you’re still not sure where to start in looking for a betta tank, try out one of the top 10 best aquariums for betta fish we’ve reviewed above. Good luck!

    my husband has just bought a Fluval Spec V for my betta and I'm quite satisfied with it. The pump is fully adjustable, down to 35 mph, and the size is perfect for a betta fish. However, it does not include a heater so that I had to buy it separately. Anyway, everything works well.

      Thanks for the feedback, Bella. Glad to hear you like it!

    Thank You! I'm looking for a small tank for my daughter. Could you give me some advice? Thanks!

    • Kate Barrington

      Hi Bella! It depends what type of fish you're planning to keep, but if it is a betta fish we recommend a minimum of two gallons but ideally 5 to 10 gallons. If you don't have a lot of space, one of the MarineLand tanks that has more vertical than horizontal space may work well. My betta likes to move from the top to the bottom of the tank, but doesn't spend a lot of time swimming from one side to the other, so it works well for me. Good luck!
