Best Betta Tank: A Buyer’s Guide to Help You Pick the Best Fish Tank

best betta tank

So you're thinking of buying a betta, or maybe you already own one of these colorful beauties and are looking to upgrade your tank. Bettas are extremely popular because, not only are they beautiful fish, but once they have the right equipment, they are very easy to take care of. When purchasing a tank for a betta, it is important to remember that bettas prefer to live alone. They become easily irritated by other fish. However, this does not mean that they will be happy in small tanks; bettas thrive when they have plenty of space to swim. Read on for a complete guide to buying the very best betta tank.

Frequently Asked Questions

1. What Makes a Betta Tank the "Best Betta Tank?"

We've already mentioned that bettas prefer roomy tanks; around five gallons is a good minimum size. The bigger the tank, the more room the fish will have to swim and the easier it will be for you to keep the water conditions stable. Small tanks are prone to ammonia spikes, which can be harmful to the fish. Bettas also need highly oxygenated water, so a tank with a filter is highly recommended.

Finally, bettas are native to places like Cambodia and Thailand, where the water temperature stays warm all year round. For a betta to thrive, its tank water must be kept above 76 degrees Fahrenheit and ideally between 78 and 80 degrees. Therefore, unless you live in a very warm climate, your fish's tank will probably need a heater and a thermometer.

2. Where Can You Buy the Best Betta Tanks?

Betta tanks can be purchased through pet supply stores or online through Amazon.

Back to the Roots Water Garden,Regular
  • Bring the garden inside with the Back to the Roots Water Garden. This mini aquaponic tank is a closed-loop ecosystem — the betta fish waste fertilizes the plants on top, and the plants filter and clean the water for your fish — not your average betta fish bowl!
  • Aquaponics is the combination of aquaculture, or fish farming, and hydroponics, or growing plants in nutrient-rich water. The fish excrete ammonia that would become toxic to the fish in a regular fish bowl. In the Water Garden, the ammonia-rich waste is pumped up to the grow bed and absorbed by the plants, helping them grow twice as fast as in traditional farming! The clean water is then filtered back to the tank, creating a low-maintenance, self-cleaning cycle to foster a healthy fish and herb garden.
  • The Water Garden aquaponic kit comes with everything you need to get started including: 3-gallon fish tank, organic wheatgrass and radish sprout seeds, a coupon for your betta fish, fish food, natural fertilizer, a silent, submersible water pump, gravel, and growstones.
  • Learn more about the science inside your fish tank — download the Water Garden curriculum at backtotheroots.com for lessons on the history of aquaponics, how it works, and the benefits of home and commerical aquaponics.
  • Grow One, Give One! Submit a photo of your growing Water Garden for a chance to win one for a classroom of your choice through Back to the Roots’ monthly giveaway. Upload your photo at backtotheroots.com/giveone.

Features

Like the last tank, the Back to the Roots Water Garden is also a closed loop aquaponics system.

It comes with several bonuses including organic wheatgrass and radish sprout seeds, a coupon for your betta fish, fish food, natural fertilizer, a submersible water pump, gravel, and grow stones.

By purchasing this tank, you also enjoy the right to participate in the Grow One, Give One contest. Just submit a photo of your tank for a chance to win another tank for a classroom of your choice.
